Computer Vision Syndrome9:05 PM
Yes, Computer Vision Syndrome is a real diagnosis, and if you work on the computer for greater than 3 hours at one sitting, you likely suffer from it! Extended computer use has been well documented to cause eye strain and fatigue, watering, burning, redness, dryness, blurry vision, and headaches. Why is using the computer so detrimental to your eyes? It is a really unnatural setting for our ocular system.
- The computer is typically 2-3 feet in front of us, forcing our eye muscles to constantly "accommodate" or strain to focus
- We blink about 50% less at the computer screen because our brain signals our eyes to stay open longer to process more information. Basically you are staring. For hours. Without a break.
- Not only is the screen unnaturally close and you are staring at it, there's also light coming from it, casting a constant glare that obscures vision
- Make sure your computer screen is not too close or too far away from you. About an arm's length is correct.
- Make sure your computer screen is positioned about 15 degrees below eye level. If the screen is above your eye level, your eyes have to stay wide open longer, causing them to dry out with time. If your screen is below eye level, your top eyelids can hang down, protecting your eyes from drying out
- Take breaks about every 20 minutes to look at a distant point across the room and blink. Allowing your eye muscles to rest from their constant focusing action at the computer can preserve their strength. If your vision is blurry in the distance when you look away, and then takes a few minutes to clear, your eyes were working WAY too hard at the computer!
