What is lutein?
Lutein, an oxygenated carotenoid, is a natural pigment widely found in vegetables, flowers, fruits and some algae. Because lutein has eight isomers and is structurally asymmetric, it is difficult to synthesize it chemically, and so far it can only be extracted from natural plants.
What is the role of lutein in the eye?
Lutein is primarily concentrated in the macular area of the retina of the eye. Electronic devices such as smartphones, tablets, and computer monitors, as well as sunlight, emit blue light, which can cause damage to the eyes with prolonged exposure. Lutein helps to absorb and dissipate this harmful blue light energy, reducing the risk of oxidative damage to retinal cells caused by the light.
Benefits Of eye health
1. Lutein supplementation may slow the progression of age-related macular degeneration. Age-related macular degeneration is the leading cause of vision loss in older adults. Over time, the macula degenerates, and the antioxidant and light-filtering properties of lutein help protect the macula from further damage.
2. Cataract prevention: Lutein may also play a role in reducing the risk of cataracts. Cataracts occur when the lens of the eye becomes cloudy. The antioxidant activity of lutein helps prevent oxidation of lens proteins, a key factor in cataract formation.
Limitations
However, if the eye has suffered severe structural damage, such as retinal detachment or severe optic nerve damage associated with glaucoma, lutein alone will not be able to repair this anatomical and physiological damage. Lutein is more of a prophylactic and supportive nutrient to maintain eye health and function rather than a medication to treat existing serious eye disease or damage.
