5 Ways to Set Up Your Home Computer to Reduce Eye Strain

Complete Family Eye Care | Computer Glasses in McKinney

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain โ€” also called computer vision syndrome โ€” according to recent data. Since COVID-19 began, the number of hours spent on a computer for tasks like working from home, online schooling, and online shopping has increased dramatically.

Symptoms of computer eye strain include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes.

If your eyes feel dry and tired, your vision is blurry by the end of the day, or your head, neck, and shoulders ache, the way you utilize your computer and other digital devices might be to blame.

How to Reduce Eye Strain

Spending less time in front of your computer is the best way to reduce digital eye strain, but if you’re working from home or you or your children are learning online, that might not be an option.

Here are 5 steps you can take to lower your risk of eye strain:

1. Use proper lighting

Excessively bright light, either from sunlight or from interior lighting, can cause eye strain.

By reducing exterior light (by closing your drapes, shades or blinds), and tweaking the lighting inside your home (using fewer light bulbs or fluorescent tubes, or lower intensity bulbs and tubes) you can lower glare and reflections off the screen.

Also, if possible, position your computer screen so the windows are to the side, instead of in front or behind it.

2. Blink more often

When staring at a screen, people blink one-third less frequently than they normally do. Blinking moistens your eyes to prevent dryness and irritation.

To reduce your risk of dry eye during computer use, every 20 minutes blink 10 times by closing your eyes very slowly. This will lubricate your eyes and help prevent dry eye.

3. Relax your eyes

Constantly staring at a computer screen can lead to focusing fatigue, which causes digital eye strain. To reduce your risk of tiring your eyes, 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.

Some eye doctors call this the “20-20-20 rule.” Looking far away relaxes the focusing lens inside the eye to reduce fatigue.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery โ€“ now or in the future? Our McKinney eye doctor has prepared the following answers to your questions about eye disease.

4. Take frequent breaks

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 reduce tension and muscle aches.

5. Modify your workstation

Poor posture also contributes to digital eye strain. Adjust your workstation and chair to the correct height so your monitor is not too close to, or too far from your eyes, or in a position that causes you to crane your neck.

Position your computer screen so it’s 20 to 24 inches from your eyes. The center of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck. With this adjustment, you will not only reduce neck, back, and shoulder pain, but reduce eye strain as well.

People experience different levels of digital eye strain, so if after you have shut down your computer the symptoms persist, then you may have a visual problem that requires attention from your eye doctor. If these symptoms are ignored and nothing is done to alleviate the eye strain the problem will only worsen.

Having a yearly checkup can help you preserve your eye health. Contact Complete Family Eye Care to learn more about how to keep your eyes healthy and reduce eye strain when working on computers.

The Best Foods for Your Eyes

We all know that eating nutrient-rich foods, drinking plenty of water, and exercising can boost our health. So it’s no surprise that these same activities also support eye health. Research has shown that regularly consuming certain vitamins and nutrients can actually prevent or delay sight-threatening eye conditions and diseases such as macular degeneration, cataracts, and glaucoma. 

Here’s a list of the best vitamins, minerals, and nutrients that can help keep your eyes healthy for a lifetime. 

We invite you to consult with our eye doctor, Dr. Kenneth Garza, to discuss which nutrients are most suited to your specific eye health and needs. 

Vitamins and Nutrients That Support Eye Health

*Always best to speak with your primary care doctor before taking any vitamins or supplements, and to ensure you consume the correct dosage for your body.

Vitamin A

Vitamin A deficiency can cause a host of eye health issues, including dry eyes and night blindness. In fact, vitamin A deficiency is a leading cause of blindness worldwide.

Vitamins A and A1, which are essential for supporting the eye’s photoreceptors (the light-sensing cells) in the retina, can be found in foods like carrots, leafy greens, egg yolks, liver, and fish. 

Omega-3 Fatty Acids

Eating Omega-3 rich foods like fatty fish can support eye health in a few ways. DHA and EPA, 2 different types of Omega-3 fatty acids, have been shown to improve retinal function and visual development.  

Omega-3 supplements can also ease dry eye symptoms. A randomized controlled study found that people who consumed Omega-3 supplements experienced improved tear quality, which resulted in reduced tear evaporation and increased eye comfort.  

Lutein and Zeaxanthin

Lutein and zeaxanthin are antioxidants that accumulate in the lens and retina and help filter out damaging UV rays and blue light. One study showed that individuals who had the highest levels of these nutrients in their diets had a 43% lower chance of developing macular degeneration than those who had consumed the least amount.  

Spinach, egg yolks, sweet corn, and red grapes are some of the foods that contain high levels of lutein and zeaxanthin. 

Vitamin C 

High amounts of vitamin C can be found in the aqueous humor of the eye, the liquid that fills the eye’s anterior chamber and supports corneal integrity. This has prompted scientists to consider this vitamin’s role in protecting eye health. 

Research suggests that regularly taking vitamin C (along with other essential vitamins and minerals) can lower the risk of developing cataracts, and slow the progression of age-related macular degeneration and visual acuity loss.

While vitamin C appears to support eye health in a variety of ways, it’s still unclear whether taking this supplement benefits those who aren’t deficient. Vitamin C can be found in various fruits and vegetables, like bell peppers, tomatoes, citrus fruits, broccoli, and kale. 

Vitamin E

Vitamin E is an antioxidant that helps protect fatty acids from becoming oxidized. Because the retina has a high concentration of fatty acids, sufficient vitamin E intake is crucial for optimal ocular health. 

Vitamin E can be found in almonds, flaxseed oil, and sunflower seeds. 

Zinc

Healthy eyes naturally contain high levels of zinc. A zinc deficiency can cause night blindness, and thus increasing zinc intake can improve night vision. Zinc also helps absorb Vitamin A, an essential antioxidant. 

Make sure to avoid taking high doses of zinc (beyond 100 mg daily) without first consulting your eye doctor. Higher doses of zinc have been associated with side effects such as reduced immune function. You can increase your zinc intake naturally by consuming more oysters, meat, and peanuts. 

Phytochemical Antioxidants

Phytochemical antioxidants are chemicals produced by plants that contain several health benefits. Some studies show that these plant-based chemicals may enhance vision and eye health as well as prevent age-related eye diseases and complications by alleviating ocular oxidative stress. Oxidative stress within the eyes contributes to several eye conditions, including  dry eye syndrome. Consuming more produce with these antioxidants can help balance the anti-oxidant and pro-oxidant system, resulting in healthier eyes. 

Personalized Eye Nutrition 

If you or someone you know is looking for ways to boost or maintain eye health, speak with an optometrist near you about what supplements and vitamins are best for you. For an eye doctor in McKinney, give us a call at 972-525-7029.

 

Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness: 

  • Age-related macular degeneration (AMD)
  • Cataracts
  • Glaucoma
  • Diabetic retinopathy

The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list. 

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss. 

The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair! 

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases. 

We Can Help Keep Your Eyes Healthy in McKinney

While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. Kenneth Garza can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.

How Smoking Impacts Vision

Smoking harms nearly every system in your body — including your eyes. 

Though we are all aware of the health effects associated with smoking, such as lung cancer, heart disease, and bad teeth, few know about the negative impact it can have on our vision. 

Smoking and Eye Disease 

Smoking, especially 20 cigarettes or more daily over a long period of time, can adversely impact your vision. Cigarette smoke is made up of compounds that can damage health and have been shown to cause cerebral lesions which affect the area of the brain that processes vision.

More specifically, tobacco addiction increases the risk of developing vision-robbing diseases such as macular degeneration (AMD), cataracts, glaucoma, diabetic retinopathy. Moreover, smoke is an irritant that can cause or exacerbate dry eye syndrome. Below we’ll delve a little further into each of these conditions. 

Age-Related Macular Degeneration 

Smokers run a high risk of developing AMD, a condition that severely impairs central vision, making it difficult or impossible to read, drive, recognize faces and colors, and leads to permanent vision loss in those aged 65 or older. Fortunately, the risk can be dramatically diminished by putting an end to tobacco smoking — even if later in life. 

Cataracts

Heavy smokers double their risk of developing cataracts, the leading cause of blindness. Cataracts are characterized by clouded, blurred or double vision, photophobia, and reduced night vision. However, cataract surgery is common and replaces the clouded lens with an artificial intraocular lens. 

Uveitis

Uveitis, the inflammation of the eye’s central layer, is an ocular disease that can lead to blindness. This condition damages important structures of the eye, notably the iris and retina, and can lead to cataracts, glaucoma and retinal detachment. Smokers have a 2.2 times higher risk of developing uveitis than non-smokers. 

Diabetic Retinopathy

Smoking raises one’s risk of developing diabetes by up to 40 percent thereby increasing the risk of retinopathy as well. Diabetes damages the blood vessels in the retina, causing them to leak blood into the eye, which — in severe cases — can deprive the retina of oxygen and result in blindness.

Dry Eyes

Dry eye syndrome is a common eye condition characterized by insufficient tears to keep your eye lubricated, or the tears are not composed of the correct balance of water, lipids, and mucous to maintain proper lubrication. Common symptoms include red, itchy, and gritty eyes.

Heavy smokers, and those exposed to secondhand smoke, not only double their risk of developing dry eye but also exacerbate an existing condition, especially among the contact lens wearers.

Secondhand Smoke and Eye Disease 

Secondhand smoke— which includes the smoke that emanates from the end of a cigarette as well as the smoke exhaled— is nearly as harmful to health and vision. Second-hand smoke places others’ eyesight in danger, particularly in young children and infants. Furthermore, studies indicate that women who smoke during pregnancy put the newborn baby at risk of being born with eye disease or visual impairment that could affect his or her ability to learn.

Stop Smoking to Save Your Vision

The good news is that giving up smoking can have an immediate effect on your health — and it’s never too late to quit! Once the habit is broken, your body will begin to repair itself to prevent vision loss. It can be challenging to quit, as it requires dedication, support, and advanced planning. Dr. Kenneth Garza and the rest of the staff at Complete Family Eye Care in McKinney care about your health and will be happy to provide any assistance or resources to help you quit smoking and improve your eye health. Keep in mind that if you smoke, quitting smoking is the most important step you can take to protect your health and vision.
