Taking daily omega-3 fatty acid supplements could help relieve your dry eyes associated with computer use, according to a study.

The study participants were 456 computer users in India who complained of dry eyes and who used a computer for more than three hours a day for at least one year.
Subjects in one group (220) were given two capsules of omega-3 fatty acids, each containing 180mg EPA and 120mg DHA, to supplement their daily diet; subjects in the other group (236) were given two capsules of a placebo containing olive oil for daily use. Each group took the daily supplements for three months.
At the end of the three-month trial, a survey of the participants revealed dry eye symptoms diminished after dietary intervention with omega-3 fatty acids, and use of the omega-3 supplements also reduced abnormal tear evaporation. The omega-3 supplements also increased the density of conjunctival goblet cells on the surface of the eye. These cells secrete substances that lubricate the eye during blinks, stabilize the tear film and reduce dryness.
The study authors concluded that orally administered omega-3 fatty acid supplements can alleviate dry eye symptoms, slow tear evaporation, and improve signs of a healthy eye surface in patients suffering from dry eyes related to computer vision syndrome.
