Dry Eye, Contact Lenses & Video Terminals

The use of video terminals by contact lens wearers may very well lead to dry eye according to researchers reporting in the December 2011 American Journal of Ophthalmology. Wearing contact lenses in an office environment and spending more than 4 hours at a visual display terminal may result in lower tear film volume with significant dry eye symptoms. The study determined contact lens wearers and long-term visual display terminal workers had significantly worse tear film than those who did not wear contact lenses or worked for shorter periods on visual display terminals. The type of lenses worn had no real effect on the severity of the dry eye however the presence an air conditioned environment did seem to worsen the symptoms.
