What Is the Long-Term Impact of Virtual Learning on Children’s Eyes?

Kids, like adults, are spending more time online. At some point during the COVID-19 pandemic, many children attended school via Zoom and completed assignments online. The trend toward more screen time — whether playing games or being in touch with friends — is likely to continue even after everyone returns to the classroom.

We already know that prolonged screen time can cause digital eye strain as well as dry eye symptoms, among other problems in children and adults. There is some indication that extended exposure to blue light may impact the development of retinal cells. However, studies on actual subjects still need to be done to establish a clear connection.

Dry Eyes

Spending a long time in front of screens can impact how quickly our tears evaporate, because we blink around 66% less when using a computer compared to other daily activities. When tears evaporate too quickly and aren’t replenished with blinking our eyes start to feel dry and gritty. So remember to blink every few seconds to prevent your eyes from drying out!

Blue Light Exposure

Screens, such as those that appear on computers, phones and tablets emit blue light. Recent studies have shown that overexposure to blue light can damage the retinal cells at the back of your eyes. This may increase the risk of vision issues such as age-related macular degeneration which eventually leads to permanent loss of vision.

Excess blue light has also been shown to disrupt the circadian rhythms that regulate our sleep patterns, as it tricks your internal clock into thinking that it is the middle of the day. This may lead to difficulty in falling asleep, insomnia, and daytime fatigue.

Digital Eye Strain

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain — also called computer vision syndrome. Symptoms of eye strain include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes.

Taking frequent breaks from your screen can help reduce eye strain and neck, back and shoulder pain during your workday.

It is recommended to take at least one 10-minute break every hour. During these breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to relieve tension and muscle aches.

Also, look away from your computer at least every 20 minutes and gaze at a distant object at least 20 feet away for at least 20 seconds. This relaxes the focusing lens inside the eye to prevent fatigue.

How to Make Virtual Learning Safer For Your Child

The following tips can lessen the impact of screens on your child’s eyes:

  • Reduce overall screen time
  • Encourage frequent breaks
  • Use accessories that filter blue light (for example, blue light glasses)
  • Schedule regular eye exams

Make Sure Your Child Gets Routine Eye Exams

Children need comprehensive eye exams to assess the health of their eyes, correct their vision and spot potential problems which can affect learning and behavior.

If you are concerned about the effect of virtual learning and screen time on your child’s eyes, or if you’re due for a checkup, schedule an eye doctor‘s appointment at Dr. Terry Tsang Optometry, Inc. in Irvine.

Q&A

What are blue light glasses?

Blue light glasses, also known as computer glasses, effectively block the transmission of blue light emitted from devices and computer screens. They often include a coating to reduce glare to further reduce eye strain. These glasses can be purchased with or without a prescription.

What’s the 20-20-20 rule?

If you find yourself gazing at screens all day, whether your computer, smartphone, iPad or television, you’re at risk of experiencing eye strain. So make sure you schedule frequent breaks from your screen and follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. And while you’re at it, use this time to get up, walk around, and stretch.

7 Tips to Keep Your Vision Healthy and Clear

Most of the information we receive from our surroundings comes through our eyes, so let’s do our best to protect them. Follow these 7 tips to give your eyes and vision the boost they need to stay healthy.

Eye Health Habits & Tips

1. Eat a Well Balanced Diet

Consuming a healthy and balanced diet filled with lots of vitamins and nutrients can help keep your eyes healthy and strong. Vitamins A, E and C, along with zinc, lutein, and omega-3 fatty acids have all been shown to support eye health and function — and reduce the risk of sight-threatening eye diseases.

2. Exercise

Exercising for at least 20 minutes each day not only gets your body moving, but also improves blood circulation in the eyes. A regular exercise routine can also help you maintain a healthy weight and lower your risk of obesity — a risk factor for several diseases that cause vision loss in adults.

3. Control Your Blood Pressure

Keeping your blood pressure within normal limits is not only important for your overall health, but for your eye health as well. High blood pressure can damage the tiny and fragile blood vessels that feed the retina, the light-sensitive tissue in the back of the eye, and result in blurred vision and vision loss. Maintaining a healthy, active lifestyle and taking the right medication, if prescribed, can help to reduce your blood pressure and your risk of vision loss.

4. Wear Sunglasses

Wearing 100% UV protective sunglasses can protect your eyes from the sun’s harmful UV rays and reduce your risk of cataracts, age-related macular degeneration and other sight-threatening eye conditions.

5. Rest Your Eyes

Spending hours each day in front of a computer screen or other digital device can lead to eye strain, fatigue and dry eye symptoms. Practice the 20-20-20 rule to give your eyes their much needed break — every 20 minutes, tear your eyes away from the screen and look at something at least 20 feet away for at least 20 seconds.

6. Quit Smoking

Smoking is hazardous to your health and affects nearly all the organs in your body, including your eyes. Cigarette smoke in particular contains toxins that have been shown to cause cerebral lesions in the visual processing area of the brain.

Smoking tobacco has also been linked to higher risks of sight-threatening eye diseases including age-related macular degeneration, cataracts and diabetic retinopathy.

7. Schedule Regular Eye Exams

Regular eye exams are a crucial part of maintaining eye health and vision. Comprehensive eye exams can detect early signs of eye disease, even before symptoms appear — facilitating earlier treatment and lowering your risk of permanent vision loss.

If you’re due for a routine checkup, you’ve noticed any changes in your vision, or you’d like to learn more about protecting your ocular health, contact Dr. Terry Tsang Optometry, Inc. in Irvine to schedule an eye exam today!

Do You Get Blurred Vision After Eating?

Have you ever gotten up from the table after enjoying a meal and noticed that things appeared fuzzy or blurry? If so, you may have experienced a temporary spike in blood sugar that affected your eyes.

If your vision is often blurred after meals, you should schedule a visit to your optometrist and general practitioner to rule out diabetes and other conditions.

The Link Between Blood Sugar and Vision

Diabetes is characterized by excessively high blood sugar levels. In some people it causes food to be digested faster than usual, leading to rapid spikes in blood sugar. Elevated blood sugar can lead to fluid to build up in the eyes, resulting in blurry vision.

The eye’s natural crystalline lens and cornea are responsible for focusing light onto the retina for clear vision. The lens changes its shape to accommodate focusing on near or far objects. In some cases, when the eye swells due to excess fluid resulting from the high blood sugar, it temporarily doesn’t focus light with the same accuracy.

Foods that are high in sugar and other carbohydrates are most likely to cause blood sugar to spike. Some examples include:

  • White rice and pasta
  • Most breakfast cereals
  • Potatoes in all forms
  • Sugary sodas and beverages
  • Candies and baked goods
  • Fruit juice

Other Possible Causes of Temporary Blurred Vision

Temporary eyesight changes don’t always mean diabetes. Intermittent blurred vision can be caused by other problems or conditions, including:

  • Carotid stenosis
  • Migraines
  • Certain medications
  • Eye strain
  • Pink eye (conjunctivitis)
  • Keratitis
  • Glaucoma
  • Macular degeneration

Many of these conditions will also present with symptoms other than blurred vision, so be sure to be open with your optometrist if you experience any unusual visual symptoms.

If you notice blurred vision only following a high-carb meal, it may be worth tracking your meals and symptoms to try and find a pattern. This information will be valuable for your optometrist and other health care professionals.

Q&A

How often do I need an eye exam?

The American Optometric Association recommends that adults have their eyes checked by an optometrist every 1-2 years. For high risk patients, patients who wear glasses or contact lenses, or those over the age of 65, annual eye exams are recommended. Certain conditions like diabetes may make it necessary to visit your optometrist more often.

Does being diabetic make a person more likely to experience vision loss?

Diabetes can negatively impact your eyes in more ways than one, but preventing vision loss and blindness is becoming easier with new technology and treatments. Having undiagnosed diabetic retinopathy puts a person at a much greater risk of going blind. If you or a loved one has been diagnosed with diabetes, be sure to schedule regular diabetic eye exams including retinal scans, to significantly reduce the chances of experiencing permanent vision loss.

What To Do if a Mosquito Bites Your Eyelid

Many of us spend the warm weather outdoors, barbecuing, camping, hiking, swimming. Although the itchy mosquito bites are typically associated with summer, mosquitos can be relentless and be a major pest, in the spring and even into the fall.

Why do Mosquitoes Bite?

Mosquitoes are small flying insects, but they don’t actually “bite”. They pierce the skin to reach a person’s blood vessels to access a source of protein for the female’s eggs. Male mosquitoes do not consume blood.

While most mosquitoes are harmless, others may carry dangerous diseases, such as malaria, in certain parts of the world. In rare cases, mosquito bites can cause other complications.

What does a mosquito bite on the eyelid look like?

A mosquito bite on the eyelid typically causes redness and inflammation of the eyelid and the surrounding area.

Since the tissue around the eye is loose, fluid accumulation and inflammation following an insect bite is common. In severe cases, it can even inhibit the eye from opening, especially after lying down, as the fluid gravitates to that area.

The skin around the eye is sensitive, so the itching and discomfort from a bite on the eyelid may feel particularly intense. Rest assured that most of the time the itchiness lasts only a few days, but try to avoid rubbing your eyes as it can exacerbate the swelling and irritation.

Are Mosquito Bites on the Eyelid Dangerous?

Usually not, but they can cause severe itching and swelling.

Young children are at a higher risk for acute swelling from a mosquito bite, as they tend to have a stronger immune response than adults do. While your child’s eye may look concerning, the inflammation should naturally subside within a few days.

Signs of an infected mosquito bite

Although uncommon, there are instances when a mosquito bite can become infected and require medical attention. Here are some signs to look out for:

  • An eyelid that develops a deep red appearance
  • An eyelid that is hot and hard to the touch
  • Discharge from the eye
  • Intense pain around the eye
  • Swelling doesn’t subside after 2-3 days

Sometimes, if the bite becomes infected, the infection will spread to the second eye and symptoms will likely be apparent in both eyelids.

If you’re experiencing any of these symptoms or if your vision is affected by your swollen eyelid, contact us for an eye exam and to determine the best course of treatment. If the eyelid isn’t infected, the following home remedies may help.

Home Remedies to Reduce Eyelid Discomfort and Swelling

Try these tips to help relieve your discomfort and promote healing.

  1. Cold Compresses. Place a cold, wet compress on your eye for around 20 minutes, 2-3 times per day to reduce the swelling and numb the itchiness. Be sure that the compress is not too cold as it can damage the skin around your eye.
  2. Allergy Medicine. Take an antihistamine, either in liquid or tablet form, to reduce itching and inflammation. Be sure to read the directions on the bottle for proper dosage information.
  3. Eye Drops. Eye drops can help further reduce inflammation and provide additional relief, especially if your vision is being affected. Vasoconstrictor eye drops are generally recommended to reduce the swelling of the blood vessels in the eyes. These drops should be used sparingly as they can cause a rebound effect – making the eyes red once they heal. It’s best to consult with your eye doctor before using any eye drops, just to be sure.

Most mosquito bites will heal on their own without any need for additional treatment. However, the eyelid is a sensitive area and may require special care to speed up the healing process.

Experiencing symptoms of an infected mosquito bite on the eye? Have any questions or concerns about your eye health or vision? We’re here to help! Simply contact Dr. Terry Tsang Optometry, Inc. in Irvine and one of our professional eye care professionals will be happy to assist.

Q&A

What is an eye infection?

An eye infection is a condition in which viruses, bacteria or other microbial agents attack the eye, causing itchy and red eyes. The infection can also affect the eyelid, cornea, and conjunctiva (the thin area that covers the inside of the eyelids and outer part of the eye).

​​What are the typical symptoms of an eye infection?

Usually people with an eye infection experience at least one of the following:

Eye pain, persistent itching, grittiness, sensitivity to light, watery eyes, fluid discharge, blurred vision, irritation, swelling and dryness. These symptoms can often be confounded with dry eye disease. To determine the source of the issue and receive optimal treatment, contact Dr. Terry Tsang Optometry, Inc. today.

6 Ways To Maintain Eye Health If You’re Over 50

Aging and certain lifestyle choices can affect your vision, especially if you’re in your 50’s and up. While it’s normal for your eyes and vision to change, there are certain actions you can take to protect your sight.

6 Tips for 50+ Eye Health

  1. Eat Well

    A well-balanced diet helps maintain a healthy body including healthy eyes, and reduces your odds of developing some very serious eye diseases. Nutrients and nutritious foods, which help prevent vision loss include:

    • Vitamin A: Carrots, spinach, kale, egg yolks, dairy products
    • Vitamin C: Citrus fruits and juices, broccoli, potatoes, green peppers
    • Vitamin E: Whole grains, eggs, sunflower seeds, vegetable oils
    • Fatty Acids: Coldwater fish, such as mackerel, rainbow trout and salmon; corn oil, sunflower oil
    • Lutein: Kale, spinach, broccoli, brussels sprouts, corn
    • Zinc: Poultry, meat, fish, dairy products, whole grains
  1. Quit Smoking

Smoking can significantly increase the chances of developing age-related macular degeneration and cataracts, as well as diabetic retinopathy in diabetics. So if you’re a smoker, the sooner you quit, the better.

  1. Exercise

Exercising for at least 20 minutes a day is great for your whole body, including your eyes, by increasing blood flow to the optic nerve and retina! It isn’t necessary to engage in strenuous exercise—in fact, a brisk walk will suffice.

  1. Protect Your Eyes

Sunglasses

Protecting your eyes from ultraviolet rays with UV-blocking sunglasses can slow down the development of cataracts, prevent sun damage to your retina, and lower the risk of skin cancer near your eyes.

Protective eyewear

Another way to protect your eyes is to wear protective eyewear. If you play sports or work with materials such as wood, glass or metal, protective eyewear can shield your eyes from splinters and shards, as well as fast-moving objects like balls and hockey pucks.

  1. Give Your Eyes a Rest

If you spend a lot of time reading, driving or looking at digital devices, you may develop eye strain and eye fatigue. By implementing the 20-20-20 rule, especially during prolonged computer or smartphone use, you can give your eyes some much-needed rest. All you need to do is this: every 20 minutes look at something 20 feet away for at least 20 seconds.

  1. Have Regular Eye Exams

And finally, a comprehensive eye exam is crucial, as it can detect eye conditions that don’t display any symptoms until vision loss has already occurred.

These conditions include:

    • Age-Related Macular Degeneration
    • Cataracts
    • Glaucoma
    • Diabetic Retinopathy

When detected early, treatment can often prevent permanent vision loss or even blindness. Less serious and more common, presbyopia or age-related farsightedness, develops with age, and simply updating your prescription for glasses or contact lenses at your routine eye checkup can keep you enjoying the arm’s-length activities you love.

Age-related vision changes can be challenging, both emotionally and physically. However, some of these can be mitigated by implementing the tips above. Schedule an eye exam with Dr. Terry Tsang Optometry, Inc. in Irvine to check your eye health today!

 

Q&A

How does aging affect your eyes?

Aging causes changes in every part of your body, including your eyes. As you age, the lens inside your eye begins to harden, which leads to presbyopia (age-related farsightedness). This makes it more difficult for your eyes to focus on near objects and tasks like reading. Other common age-related eye problems include:

  • Age-Related Macular Degeneration
  • Cataracts
  • Glaucoma
  • Diabetic Retinopathy
  • Dry Eyes
  • Floaters
  • Changes to Peripheral Vision

Can I do anything about my chances of vision loss?

It is estimated that half of all visual impairment and blindness can be prevented through early diagnosis and treatment. So make sure you get regular eye exams to ensure that all is in check.

 

Is It Really That Bad to Sleep or Shower In Contact Lenses?

Is it safe to wear contact lenses while showering or sleeping?

No. It’s absolutely not safe to wear contacts while immersed in water or when sleeping (unless you have contacts specifically intended for overnight wear).

Sleeping in your contact lenses can dry out your eyes and potentially harm your vision as a result of infection. Contact lenses should also be kept away from water as it’s a natural breeding ground for bacteria and microorganisms, which can get trapped under the contact lens, putting you at risk of a waterborne eye infection.

Why Does Sleeping in Contacts Increase the Risk of Infection?

To stay healthy, your corneas require hydration and oxygen. Blinking keeps your eyes wet, and the tears you produce allow oxygen to enter your eyes.

Sleeping in standard contacts limits the amount of oxygen and hydration that reach your eyes. As a result, your corneas are more dry and susceptible to corneal abrasion, and they have a harder time fighting bacteria, causing your eyes to be more prone to infection.

If, after sleeping in contact lenses, you experience blurred vision, discharge from your eyes, redness or watering, you may have an eye infection. Left untreated, infection can lead to corneal damage, and—in extreme cases—loss of vision.

What are the Risks of Showering While Wearing Contacts?

Contact lens wearers are more likely to develop keratitis, an inflammation of the cornea, if their lenses come into contact with water. Left untreated, keratitis can cause vision loss.

In microbial keratitis, microorganisms invade the cornea and cause an infection of the eye. The microorganisms that cause these infections can be found in a variety of water sources, including rivers, lakes and streams, showers, tap, a pool or jacuzzi. Normally, the antimicrobial properties of tears protect your eyes, but that process is hindered by contact lenses.

Furthermore, contact lenses can stick to your eye when exposed to water, potentially leading to corneal abrasions. These scratches may enable microorganisms found in non-sterile water to penetrate the cornea and cause an infection.

Eye Care Tips for Contact Lens Wearers

  • In order to avoid eye infections, it’s important to follow the tips below. However, do not consider these tips as medical advice. Always speak to your eye doctor for individual advice on wearing and caring for your contact lenses.
  • Avoid water while wearing contacts. Keep your contacts away from water. Make sure to remove your contacts before showering, bathing, or swimming. Don’t rinse or store your contacts in water, and if it does occur, make sure to throw away or disinfect them thoroughly.
  • Don’t sleep in your contacts. Avoid wearing your contacts when sleeping, unless you have special overnight lenses or your eye doctor has told you that it’s safe to do so.
  • Use clean hands. Always wash your hands and dry them thoroughly before touching your contacts.
  • Follow product instructions. Always follow the directions when cleaning or disinfecting your contacts.
  • Store contacts properly. Make sure your contacts are exclusively stored in fresh contact lens solution. Never reuse old solution.
  • Wear contacts for the proper length of time. Avoid wearing your contacts for longer than the recommended time period.

So, remove those lenses before going to bed and showering. If you experience symptoms like eye pain, discharge, or sensitivity to light, immediately remove your lenses and consult Dr. Terry Tsang Optometry, Inc. in Irvine without delay.

Q&A

Who can wear contact lenses?

Almost everyone can wear contact lenses, no matter their age, prescription or lifestyle.

What if I accidentally fall asleep with my contacts?

If you fall asleep with your contacts on, you may wake up with them attached to your eye’s surface. If they don’t come out easily, blink and apply lens drops until the surface of your eye is moist. That should make it easier to remove the lenses.

What Eye Drops Are Best For My Eyes?

Are you suffering from red, irritated and scratchy eyes? Do you feel like you have something stuck in your eyes? These are hallmark symptoms of dry eye syndrome, a condition that occurs when your eyes are not properly lubricated due to insufficient tear production, blocked glands, or unbalanced tear composition.

The symptoms can be so unpleasant that many rush to the nearest pharmacy to find the perfect eye drops that will offer them the relief they need so that they can get back to focusing on other things.

However, seeking the ideal artificial tears to relieve dry eyes can be a daunting process. The eye drops shelf at the drug store offers so many options that it’s hard to know which ones are right for you. What’s more, some can actually make your symptoms worse.

Not all eye drops are created equal—currently, there are 6 main categories of artificial tears available over the counter. Choosing the artificial tears based on your specific needs can help narrow your options.

The 6 Types of Eye Drops / Artificial Tears

Preserved Artificial Tears

Preserved artificial tears contain added preservatives to maintain a very long shelf and keep bacteria at bay once the bottle is opened. Unfortunately, it also causes inflammatory dry eye disease, meibomian gland dysfunction and an allergic reaction in those who are sensitive, leading to redness, irritation and inflammation. While these drops may offer temporary relief, long term they can do more harm than good. Moreover, the preservatives may leave residue on contact lenses.

Preservative-Free Artificial Tears

Preservative-free artificial tears are great for contact lens wearers as they don’t cause any preservative build-up on the lenses. They are also suitable for those with sensitive eyes since they contain fewer ingredients that can cause irritation.

Preservative-free eye drops typically come in a box of 28 to 30 small vials that fit in a pocket or purse.

To use these drops, just pop the top off and insert the drops into your eyes. Some of these vials can be re-capped to allow you to continue to use the vial for up to 24 hours, but not longer. Refrigerate opened vials between uses to prevent any bacterial growth.

Oil-Based Artificial Tears

Oil-based tears come in preserved and preservative-free versions. These are thicker than traditional eye drops, as they contain an oil-based formulation. The oil helps prevent the watery portion of the tears from evaporating too quickly.

If you suffer from moderate or severe dry eye, oil-based artificial tears may be a great option. However, they’re not recommended for contact lens wearers, as the oils may stick to the surface of the lenses, making it difficult to keep them clean.

Eye Drop Spray or Mist

These sprays are preservative-free and are used to relieve dryness and irritation in both the eyes and eyelids. They’re easy to use, especially for those who struggle to insert drops into their eyes.

To use the spray, just close your eyes and spray onto your closed eyelids. Once you blink, the tears will slide into your eyes.

Don’t use the spray if you’re wearing makeup, lotions, or creams on your eyelids, as it can cause the makeup or lotion to enter your eye.

Artificial Tear Gel

Artificial tear gel adds a thick coating of tears and can be used at any time of the day or night. However, the thicker consistency of the gel drop may blur your vision for several minutes.

The gel is applied in the same way as eye drops. It effectively soothes the eyes and provides extended relief for both moderate to severe dry eye.

Most artificial tear gels contain preservatives, so they can only be used up to 4 times a day, and usually they are not safe for contact lens wearers.

Artificial Tear Ointment

Dry eye ointments are thick and coat the front of your eye. They’re usually used 1 to 2 times daily as needed. It may be best to use them at bedtime, as it will blur your vision.

Get Dry Eye Relief Today!

Artificial tears may be a good way to temporarily relieve eye dryness. However, using the wrong type of eye drops can be worse than not using any drops at all. So be sure to consult your eye doctor before you get eye drops.

Keep in mind that eye drops don’t address the root cause of dry eyes; they just provide temporary respite from the uncomfortable dry eye symptoms. Only an eye doctor can examine your eyes to determine the underlying cause of your symptoms and recommend the best treatment for your unique case of dry eye.

Schedule an appointment with Dr. Terry Tsang Optometry, Inc. in Irvine to learn more about dry eye syndrome and to find out which treatment is best for you.

Q&A

What is dry eye syndrome?

Dry eye syndrome is a condition where your eyes either produce low-quality tears or don’t produce enough tears to keep your eyes hydrated. This may be due to certain diseases (like diabetes or other autoimmune diseases), aging, allergies, hormonal changes, smoking, poor air quality, medications and the environment.

What are the symptoms of dry eye syndrome?

Dry eye syndrome can cause a wide range of symptoms including:

  • Itchy eyes
  • A feeling that there is grit or debris in the eye
  • Blurred vision
  • Burning sensation
  • Dryness
  • Irritation
  • Sensitivity to light and glare

 

Why Are Blue Eyes More Sensitive To Light?

Did you know that blue eyes don’t contain any blue pigment? They appear blue due to how the light reacts with the structures of the iris.

In fact, the top layer of a blue iris doesn’t contain any pigment at all. This lack of pigment is the reason that blue-eyed people may be more sensitive to bright light and have a greater need to wear sunglasses than their brown-eyed counterparts.

Why Do Your Eyes Need Sun Protection?

Eyes of all colors need shielding from the sun’s harmful ultraviolet (UV) rays. Exposure to UV light can contribute to the formation of short-term and long-term eye conditions such as corneal sunburn and macular degeneration.

That’s why it’s so important to choose high-quality sunwear with 100% UV blocking lenses, and to throw on a sun hat for an added layer of protection.

UV protection is important for individuals of all ages—especially children—who are more susceptible than adults to the sun’s harmful rays, and tend to spend more time outdoors. It is estimated that up to 80% of a person’s lifetime exposure to UV rays happens before the age of 18.

Why are Blue Eyes More Sensitive to Light?

Lighter colored eyes like blue, hazel and green have less of a pigment called ‘melanin’ than brown eyes do.

Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.

If you have blue eyes, you may have experienced this first-hand. Bright light may be uncomfortable or you may want to reach for your shades as soon as you leave the house on a sunny day.

That’s why optometrists urge blue-eyed patients to be particularly vigilant about UV protection, so as to mitigate their chances of developing eye disease and other complications.

How We Can Help

Whether you have blue eyes or not, sunglasses are an important part of keeping your eyes healthy for a lifetime.

At Dr. Terry Tsang Optometry, Inc., we’ll be happy to advise on the perfect high-quality and protective pair of sunglasses to suit your needs and personal style.

To learn more about the eye care services we offer or to schedule an eye exam, contact Dr. Terry Tsang Optometry, Inc. in Irvine today!

Q&A:

#1: Should I wear sunglasses even when it’s not sunny outside?

Yes! You should wear your sunglasses whenever outdoors during the day, even on an overcast, winter day. UV light can pass through clouds and reflect off surfaces like car windows and pavement.

#2: What type of sunglasses are the most suitable for blue eyes?

The most protective sunglasses are wraparound sunglasses that protect the eyes from every angle. You can also opt for photochromic lenses, which offer total UV protection but only become tinted when exposed to outdoor sunlight, and turn clear when you come indoors again. Your optometrist can help you choose the best lens and frame options for your needs and lifestyle.

Childhood Myopia Is in Crisis Mode on a Global Scale

When it comes to the prevalence of myopia (nearsightedness), the statistics are staggering. By 2050, nearly half of the world’s population—about 5 billion people—will be myopic. Below are a few useful tips to help you prevent your child from being part of that statistic.

What Is Myopia?

Myopia occurs when the eye elongates, causing light rays to focus in front of the light-sensitive retina rather than directly on it, while looking at something far away. So, people with nearsightedness perceive distant objects as blurred while close-up objects can remain clear.

Myopia tends to develop during childhood, when the eyeballs rapidly grow (along with the rest of the body), mainly between the ages of 8-18. It can worsen slowly or quickly, but it is not simply an inconvenience. People with progressive myopia are more likely to develop serious eye diseases like cataracts, retinal detachment, macular degeneration and glaucoma later in life—conditions which may lead to permanent loss of vision and even blindness.

How To Know Whether Your Child Is Myopic

Below are some telltale signs to watch for:

  • Blurred distance vision – Objects in the distance are blurred; kids may complain that they can’t see the board
  • Headaches – When myopia isn’t corrected, it can cause eye strain and headaches.
  • Head tilting or squinting – If your child squints or tilts his or her head while watching TV, for example, it may be a symptom of myopia.
  • Looking at objects too closely – If you notice your child moving closer to the TV or squinting as they try to see the writing on the board, it may indicate myopia.

What Parents Can Do to Slow Their Child’s Myopia Progression

  • Encourage your child to go outdoors for at least 90 minutes a day, preferably in the sunshine. Studies show that playing outdoors reduces the risk of developing myopia and slows its progression.
  • Limit the amount of time your child spends staring at a screen, reading and doing close work such as homework.
  • When your child uses a digital screen, make sure that it isn’t too close to the face.
  • Teach the 20-20-20 rule: During screen time, take a break every 20 minutes to look at an object across the room or out the window about 20 feet away, for at least 20 seconds.

How We Can Help

Certain eye doctors offer treatment methods known as myopia control or myopia management. These include orthokeratology, bifocal or multifocal contact lenses, and eye drops like low dose atropine. Regular eyeglasses and contact lenses don’t prevent its progression but do correct myopia so the child can see and function normally.

If your child shows signs of myopia, schedule an eye exam with Dr. Terry Tsang Optometry, Inc. in Irvine as soon as possible.

Q&A

How is myopia diagnosed?

Your child’s eye doctor will perform a thorough pediatric eye exam to diagnose myopia, which often includes a visual acuity test, where the eye doctor will use an eye chart made up of letters of varied sizes. If the test results indicate myopia, then the optometrist may shine a light into their eyes and evaluate the reflection off the retina to determine the degree of refractive error for their prescription.

Can myopia lead to blindness?

High myopia may increase your child’s risk of developing more serious eye conditions later in life, such as cataracts, retinal detachment and glaucoma. Left untreated, high myopia complications can sometimes lead to blindness—which is why routine eye exams are critical.

Is It Normal To Have Long-Lasting Symptoms After A Head Injury?

man in blue and brown plaid dress shirt touching his hair 897817Perhaps you can relate to one of these scenarios:

After sustaining a mild head injury in a car accident, you now have trouble focusing any time you try to read. You can’t concentrate and feel the need to shut or cover your eyes to find some relief.

Or maybe your child fell and took a blow to the head while playing sports and has complained of headaches ever since. Traditional headache remedies just aren’t effective, and your primary care doctor assures you that no obvious brain damage has occurred and that the headaches will resolve shortly — but they persist.

For the estimated 1.5 million Americans who suffer from traumatic brain injuries (TBI) every year, these scenarios are typical of post-TBI struggles. Concussions and other forms of TBI can seriously impact lives by generating long-lasting symptoms. Fortunately, a neuro-optometrist can provide a crucial component to the healing process with neuro-optometric rehabilitation therapy.

If you or a loved one has suffered even a mild TBI, call Dr. Terry Tsang Optometry, Inc. to schedule a functional visual evaluation and determine if you can benefit from neuro-optometric rehabilitation therapy.

What Types of Symptoms Follow a Head Injury?

The brain controls much of what goes on in our bodies, so it’s no surprise that a TBI can produce a wide range of symptoms. Below we’ll discuss the most common symptoms and how we can help treat them.

Visual Difficulties

Approximately 90% of all TBIs result in some degree of visual dysfunction. When the eye-brain connection is disrupted, a decrease in visual ability results. Some visual difficulties that may follow a TBI include:

  • Blurred or double vision
  • Photophobia (sensitivity to light)
  • Convergence insufficiency — the inability of the eyes to focus on a near object
  • Binocular vision disorder — eye turn or lazy eye
  • Problems with eye-tracking or eye-teaming
  • Difficulty reading or often losing your place while reading
  • Color contrast issues
  • Peripheral vision defects
  • Eye strain or tired eyes
  • Decreased visual acuity

Headaches and Migraines

In many cases, headaches, including migraines, can be caused by a visual dysfunction. Following a TBI, the ocular muscles will need to exert extra effort to compensate for trauma to the visual system. This additional effort can lead to eye strain.and cause pain in the temples and forehead similar to —and often mistaken for— a tension headache or migraine. Correcting the visual problem will, in many cases, alleviate the intensity and frequency of headaches, or eliminate them entirely.

Dizziness and Balance Problems

The eyes provide the brain with vital information regarding balance and coordination, so when the eye-brain connection is affected you may feel off-balance. This is especially true when a binocular vision disorder is present. Even the slightest misalignment of the eyes can make you feel dizzy, light-headed, or lose balance. Small degrees of misalignment can often be overlooked during routine eye exams, making it all the more important to see a neuro-optometrist in the presence of symptoms.

Concentration

Another possible after-effect of a concussion or other TBI is difficulty concentrating, especially when reading. It may be challenging to keep your place on the page or smoothly navigate along a sentence without having to stop and close your eyes momentarily for relief. Other potential challenges include problems with comprehension, memory difficulties, or trouble with multitasking.

How A Neuro-Optometrist Can Help

Neuro-optometrists are Doctors of Optometry (OD) who’ve been through postgraduate training to assess and treat visual disorders related to TBI and other similar conditions. The goal of neuro-optometric rehabilitation is to retrain the eyes and brain to work in unison and regain clear and comfortable vision by using specific visual exercises. Just as with any other rehabilitation therapy, the earlier one starts the rehabilitation program following a TBI, the higher the chance of recovering lost visual skills.

Dr. Terry Tsang Optometry, Inc. provides neuro-optometric rehabilitation therapy and other services to patients from Tustin, Lake Forest, Newport Beach, Mission Viejo, and throughout California.
