Contact lens wearers need to remember to blink while they work at their computer. Computer use results in a decrease of blinking to almost one third of normal, while the straight-ahead gaze needed to look at a screen exposes more of the eye to the air. Combined, this causes the eye to dry out and become itchy much faster than usual, especially when a contact lens is resting on the cornea. If frequent blinking is not enough to eliminate the dryness and itching, an ophthalmologist can prescribe eye drops made especially for contact lenses.
