dry eyesA condition in which the eyes feel dry or have a burning or stinging sensation due to an insufficient amount of tears. Dry eyes can be caused by the lack of blinking, which often occurs when users stare at a computer screen. It is also caused by aging, smoking, a dry environment as well as cold and allergy medicines. Prevention from computer-caused dry eyes is to consciously make an effort to blink a few times per minute. See medical conditions.
