The human eye contains high levels of DHA (docosahexaenoic acid), and its role sitting at the very foundations of cell membranes within the eye. In fact, Omega-3 fatty acids are high in density around the eye and brain, due to the accumulation in infancy. It’s understood that the role of DHA is to regulate membrane-bound proteins, which are responsible for the care of cellular capacity. It may also order the receptors and kinetics of membrane carrier methods within the body.
Age-associated vision loss, such as Macular Degeneration, is a form that is related to damage to the macula, or centre of the eye. This damage can be a result of smoking, high blood pressure, exposure to UV radiation and a nutrient diet. Studies have shown that natural treatments for macular degeneration are omega-3 fatty acid capsules that carry DHA because it helps relieve fluid pressure within the eye.

Of course, if you’re worried about fish sources, try a vegetarian Omega 3 supplement instead, from algal oil.
Solve Dry-Eye Irritation from Computer Use with Omega-3
The researchers concluded that orally administered omega-3 fatty acid supplements can prevent 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.
