The symptoms of Computer Vision Syndrome fall into three broad categories. visual, ocular and general. The visual category includes blurred or double vision, changes in perception of color, glare and flickering sensations. The ocular category includes irritated or tired eyes, burning or itching eyes, excessive tears, dry eyes, excessive blinking, squinting, sore eyes, discomfort in contact lenses, sensitivity to light, etc. Finally the general category includes, neck and shoulder pain or tension, pain in the back or arms, headache, drowsiness or excessive fatigue, prone to making errors, nervousness and irritability.
