Computer Eye Strain Symptoms


By Tom Hanks at 2010-11-11 23:49:47
Twenty years ago most of our reading was done via print, now most of it is via pixel. This requires a different type of focusing from our eyes, which we have yet to become accustomed to. A result of this is constant stress on the eyes and visual system that causes blurred vision, headache, eye strain, dry eyes, difficulty focusing the eyes at various distances, double vision, light sensitivity and neck and backaches.

Computer eye strain normally strikes in the office environment where people are constantly staring at computer monitors day in and day out. However, students who are constantly online researching and writing term papers and anyone who enjoys playing video games or surfing the net can also suffer.

This form of strained eyes can make your days feel longer and harder than they need to be because it causes headaches, sore and tired eyes among other annoying symptoms. Your eye muscles are being worked so hard that they struggle to focus and your eyes can become itchy, dry, watery or blurred. You can lose concentration and this can affect your career.

According to the Vision Council of America, nearly 90 percent of those who use a computer, (and we can replace this with digital device), at least 3 hours a day suffer vision problems associated with computer related eye strain.

Though basically people experience the same Computer eye strains, but you may also experience something very specific. Some of the strains that may show up after a whole day staring at the computer screen are pain in the eye, blurry eyes, dry eyes, headache, false near sight (pseudomyopia).

This is what your eyes go through day in and day out when you are using a laptop or desktop computer. Although you may not realize it, your eyes contain tiny muscles that are being used when you are working on one of these devices. Your eye muscles are in control of focusing on the screen and concentrating on your tasks. When they are overworked, or overtired, strain on our eyes occurs.

Pixels are brightest at the center and diminish in intensity toward their edges which causes the eyes to strain to regain focus on the screen. Digital eyewear, (aka computer glasses, computer eye strain glasses etc), is a relatively simple way to reduce computer eye strain.

Digital interaction happens primarily in the Intermediate vision zone and requires the eyes to remain fixed in focus. Both the use of this vision zone and the requirement to fix focus are new demands for our eyes and as such are experienced as strains.

They are most likely sore and tired from working the muscles. Now, consider how your eye muscles feel when they put in an 8 hour day, 5 days a week? Even though you may not realize it, when you are looking at a screen or monitor for a long time, you are using tiny muscles in your eyes. No wonder they are so sore!
