Omega-3 Fatty Acids (2015) & Computer Eye Syndrome
Learn about managing computer eye strain.
This study recommended 1,000mg-2,000mg per day dosage for omega-3 in treating dry eye syndrome (one of the symptoms of computer eyestrain).2
In order to evaluate the efficacy of omega-3 fatty acids in treating computer eye syndrome, researchers used standard measures of dry eye symptoms - the Schirmer test, the time it takes the tear film to degrade, and conjunctival impression cytology, which is a test to evaluate the surface cells of the surface of the eye. 1
Almost 500 patients who had been using computer for at least 3 hours a day for at least a year were randomly divided into a test group and a control group. The control group was given capsules containing olive oil. The test group were given capsules containing 180mg EPA and 120mg DHA.
After 3 months there was a distinct difference in the test scores demonstrating that oral omega-3s are helpful for dry eye symptoms that result from computer eye strain.1
Another study with older women showed reduced risk of dry eye syndrome with a high dietary intake of omega-3 fatty acids.3
