DHA (docosahexaenoic acid, omega-3) is a large fatty acid molecule that is found in a high concentration in the retina. The retina's light-sensing cells contain densely packed arrays of rhodopsin, a protein that enables vision in low-light conditions, packed into their cell membranes. Membranes are thin molecular sheets that are typically loaded with enzymes and other active proteins. Every cell is built on membranes, which power cell functions and are the foundation of the body's overall metabolic efficiency.
DHA is indispensable for healthy membrane function, most especially in the highly active cells of the retina and the brain. The optimal functioning of rhodopsin is considered to be supported by the presence of DHA in the retinal membranes. Lutein, zeaxanthin, and meso-zeaxanthin are three carotenoids that belong to the xanthophyll subclass. They endow the retina with potent protection against damage from light energy. These carotenoids are also antioxidants that protect against harmful molecules produced from processes in the body.
Humans cannot make lutein and zeaxanthin so it must be obtained through the diet. The retina can make meso-zeaxanthin which requires lutein. Taurine is found in high concentrations in the retina, but those levels can decline significantly with age. When taurine levels are deficient, a variety of vision problems can occur, indicating its vital role in retinal structural integrity and function. By regulating calcium uptake in retinal tissue, taurine plays an important role in the visual signaling function of the retina.
