Eye expert discusses dry eye resulting from computer usage.

Irish Health (9/24, Hunter) reported that "people who work for long periods at a computer screen" should take "precautions to prevent the risk of developing eye conditions."

Prof. Moore emphasized the importance of adjusting the both the chair and the computer screen "to the correct height to help position one's upper lid to reduce the amount of tear evaporation," thereby controlling "dry-eye symptoms without the need for medication." In addition, "Prof. Moore said it is equally important to keep well hydrated in an air-conditioned environment."
