Computer Vision Syndrome

Computer Vision Syndrome (CVS) is a real condition that optometrists have been familiar with for many years, yet most folks don't know what it is or that they may be it's unsuspecting victim. I personally see several patients a week who exhibit at least some of the signs and symptoms of this little known anomaly.



The American Optometric Association (AOA) defines computer vision syndrome as "the complex of eye and vision problems related to near work that are experienced during or related to computer use." While the full study of CVS is beyond the scope of this blog, suffice it to say that the age of computers, which is here to stay, has brought about a whole new set of problems, many of them vision related. As you can imagine, computers force us to stare at a screen for long periods of time, causing postural problems in addition to myriad vision issues including:



1) Dry eyes due to reduced blinking.

2) Headaches and focusing problems due to eye fatigue/ breakdown of our internal focusing system.

3) Eyestrain due to screen glare and/or poor character resolution. LCD screens are superior to others because they reduce flicker, which can tire the eyes.



Healthy computer use includes maintaining a 20- 26 inch (approximately arms length) distance between your eyes and your computer screen, a postural angle at the hips of 90 degrees, a straight back, and your feet flat on the floor. Keeping a slightly downward line of sight toward the screen tends to relieve neck strain, and taking frequent 10-20 minute breaks from the computer helps to keep the eyes' focusing system flexible. Lastly, remember to blink frequently, use artificial tears as needed (NOT VISINE), and visit your family optometrist to see if a good pair of computer glasses may be of benefit.



Have a great weekend!
