Omega-3s May Help Reduce Symptoms of Computer-Related Dry Eye
Computers have become a part of most people’s daily lives, but they can pose certain health risks such as dry eye. A recent study suggests that omega-3 supplements may help improve symptoms of dry eye associated with prolonged exposure to computer screens.
Dry eye is a disorder of the tear film due to tear deficiency or excessive tear evaporation, which causes damage to the interpalpebral ocular surface.
Participants in the study included 478 people with dry eye who were using computers for at least three hours per day for a minimum of one year. They were given either daily omega-3 supplements that included 360 mg EPA and 240 mg DHA or a placebo in the form of olive oil daily for three months.
The researchers recorded dry eye symptoms, the Nelson grade, Schirmer test, tear breakup time (TBUT), and conjunctival impression cytology. The Nelson grade measures the severity of dry eye, and the Schirmer test is used to determine if the eye is producing enough tears to keep it moist.
At the conclusion of the study, the omega-3 group had significant improvements in dry eye symptoms, the Nelson grade, the Schirmer test, and TBUT scores. The researchers pointed out that this suggests that omega-3s may help with inherent tear film stability, rather than merely increasing tear volume and production.
Researchers from the Laser Eye Clinic in Noida conducted the study. It was published online ahead of print on February 16, 2015, in the journal Contact Lens and Anterior Eye.
Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.
Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s.
