Stay Stacked: Eyes Versus Computers

Stay Stacked

Computers are changing the way we see the world — but are they also changing the way we see?

These days, it’s rare to find someone who doesn’t spend hours everyday on a computer, and doctors are seeing more cases of Computer Vision Syndrome (CVS), which is caused by just that. Poker players easily spend more time staring at a computer screen than the average office worker, particularly with extremely focused attention. So, we're going to take a look at some information and strategies for preventing a case of CVS or general eyestrain, which can have quite a negative impact on your mental game.

Dr. S. Singh, an 
ophthalmologist at the Castleman Eye Center in Michigan says, “No study has proven that long-term computer work truly damages the eyes; 
it could however lead to strain, fatigue, headaches and symptoms of dryness 
(gritty sensation, vision starts off clear but blurs with time).”

The most common strategy for preventing these symptoms and the onset of CVS is by following the 20/20/20 Rule. Dr. Singh explains, “While on the computer, every 20 minutes, take a 20
 second break, and look at least 20 feet away, whether it be out the window or down the hall. This, along with the use of some over-the-counter lubricating eye drops three to four 
times a day, will help with the previously mentioned

VSP optometrist, Dr. Leanne Liddicoat, also recommends the 20/20/20 rule, along with the following strategies:

  • Ensure proper lighting: Poor lighting often causes eyestrain, whether it’s irritation from overexposure by lights that are too bright, or strain from lights that are too dim. Ease strain on the eyes by keeping overhead bright lights to a minimum and positioning
 your desk lamp to shine onto your desk, not at you. Position your
 computer screen in a way that reduces reflections and glare from windows 
or lights. 

  • Working distance: The closer your eyes are to the object you are
 looking at, the harder your eyes have to work. A good rule is to apply 
the Harmon Distance (the distance between the elbow and first knuckle) 
as a guide.
  • Eye exams: All adults should have an annual
 eye exam to help detect underlying vision problems. 

Do You Wear Contacts?

If you wear contact lenses, there is even more reason to ensure that you keep your eyes lubricated. Dr. Kurt J. Hofeldt explains that when we try to focus on back-lit products, our eyes don't blink as much. This causes our eyes to dry out quickly. Patients wearing contact lenses need even more moisture and a better tear film to maintain better eye comfort, health, and vision. If a patient's contact lenses dry out, the lens can easily stick to the eye and upon removal from a dry eye can damage the epithelium (top skin layer of cornea), potentially leading to other problems.

How About a Pair of Glasses?

There are many options available for reducing glare from the computer screen for people who already wear glasses, or for those who don't. Lacey Morgan from Media Eye Works Optical in Pennsylvania shares a couple of options:

Chemistrie lenses are a magnetic lens system that fits over your current eyeglasses by simply clipping on or off with tiny magnets. The yellow or rose colored polarized lens helps to reduce the glare from the computer screen and increase comfort during extended use. Of course, all poker players have a beloved pair of sunglasses that they wear at the live poker table, and you can have selected types of sunglasses fitted with this technology also for your online sessions.

If you don't already own glasses, then Gunnar Eyewear (pictured above) is another great option that's specifically designed for gamers. They offer yellow-tinted glasses designed to help reduce eyestrain and glare for extended computer use. These are highly recommended by many optometrists. You can pick up a pair of Gunnar Eyewear at your local Best Buy.

The Liver

It is also believed that the liver nourishes and moistens the eyes. When the liver is deficient in the required nutrients, it can cause problems such as blurry vision, myopia, “floaters” (dark specks, spots, threads or clumps in front of your eyes), color blindness, or dry eyes. When there is a "heat" in the liver, eyes are likely to be bloodshot, often with a painful or burning sensation. If you feel like you need an additional boost to your eye health, then perhaps try the herbal product EyeCare™ by Canfo, which focuses on providing the liver with the nutrients needed for overall liver health and wellness, which could then ensure that your eyes are nice and prepared for when you finally reach that final table.

Test Yourself

While this should never replace a full eye examination by a professional, why not test your eyes now on your iPhone or iPad for a bit of fun? I downloaded Vision Test by 3 Sided Cube Design Ltd, which measures your visual perception, long-distance vision, and color accuracy. According to the app, my lifestyle maybe be affecting my eyesight, hence my motivation to write this article!
