Computer Vision Syndrome

-back to Patient Education-

Normally, the human eyes are adapted to relax for viewing distant objects and they focus AND CONVERGE to focus on near objects. This focusing is achieved with effort applied by the intra-ocular muscles. When we view a computer screen placed at or near eye level for extended periods of time our visual system is operating in manner that it is not ideally suited for. Imagine carrying a book held straight out from your body versus allowing it to hang down at your sides. This exertion causes strain, and when it effects our eyes we can experience a variety of symptoms collectively called COMPUTER VISION SYNDROME.

Typically, complaints may include:

Blurry vision
Scratch, dry eyes
Eye strain
Headaches
Neck and shoulder aches

The causes are usually a combination of factors:

The monitor itself (the flickering of the image on the screen)
Poor lighting
Viewing distance or Viewing angle
Posture
Uncorrected or Un-diagnosed vision deficiency

Most symptoms can be relieved by taking a few simple steps.

LIGHTING: Soft, even room lighting will reduce or eliminate glare off of the screen surface. An anti-glare screen may help. And eyeglass wearers should have a good ANTI-REFLECTIVE COATING on their lenses to also minimize reflected glare.

COMPUTER LOCATION: Try to position the monitor slightly below eye level and about 24” away. Many people report more comfort if their reference material is positioned in front of them between the keyboard and the monitor to reduce side-to-side head turning.

REST BREAKS: Remember to take a break, even for just 1 minute, every 15 to 20 minutes. Look off in the distance to let your eye muscles relax, and while you’re at it walk around a bit to reduce posture related stress.

BLINK: Sounds silly but remember to blink often to moisturize your eyes and reduce DRY EYE symptoms.

EYE EXAMINATION: Not only should you have your vision checked and corrected but tell your eye doctor that you spend a lot of time on a computer. The eyeglasses that you wear for distance or reading ARE NOT IDEAL for computer use, and you may need a prescription specifically suited for the INTERMEDIATE focus area that computer screens occupy.
