Some experts agree, but say the actual screen may not be what’s causing the damage. “While computers have no known harmful effects on eyesight, computer users do often complain of eye-related symptoms like eye strain, headaches, fatigue and difficulty focusing,” says Surjinder Sahota, president of the British Columbia Doctors Of Optometry. “These symptoms, however, are caused not by the computer screen itself, but rather by the conditions surrounding the computer screen.”
Sahota says poor lighting, improper placement of computer equipment and even computer furniture may all cause our eyes to be irritated after staring at a screen too long.
Our eye muscles function like any other muscle in our body. When muscles become fatigued, the eyes may feel uncomfortable or ache and vision may start to blur,

“Look away from your computer at least every 20 minutes and gaze at a distant object 20 feet away for 20 seconds,” she says.
