Computers and eyestrain.

Computer video display terminals have revolutionized the home and office work habits of millions of people. Although no verifiable organic ocular diseases have been shown to derive from computer monitors, symptoms related to eyestrain are very common. Some 10% to 15% of patients presenting for routine eye exams complain of computer-related headache and eyestrain. Comprehensive ocular examination including distance, intermediate and near refraction, as well as uncovering evidence of ergonomic and lighting inadequacy, often is clinically quite helpful. A careful eye exam with particular attention to middle and near range refraction, oculomotor balance, the workstation, lighting, and seating comfort will assist measurably in alleviating eyestrain.
