Functions and Applications
What does lutein do for your eyes?
The antioxidant abilities of lutein help fight free radical damage caused by blue light or sun exposure, a poor diet, and other factors that increase the risk of developing age-related vision loss or disorders. These include problems like macular degeneration and cataracts.
In the process, antioxidants like lutein protect healthy cells while halting the growth of malignant cells.
Within the eyes, one of the most important functions of the lens is to collect and focus light on the retina. That is exactly why the lens needs to remain “clear” and free from the cloudiness that is indicative of cataracts. The major reason the lens becomes cloudy is damage due to oxidation. This is why we need antioxidants to help neutralize free radicals.
Even in people who have existing eye damage, including plenty of lutein in their diets can help stop the condition from progressing and further damaging vision.
This eye vitamin isn’t just beneficial for older adults — taking preventative measures is the real key to preserving your vision and eye health. Both older and younger people should consume plenty of lutein in order to reduce the risk of oxidative damage that can lead to disorders down the road.
Although carotenoids are extremely important for vision and your eyes, their benefits don’t stop there. Aside from protecting eyes, lutein uses also include helping prevent skin disorders, several types of cancer including colon or breast cancer, type 2 diabetes, and risk factors associated with coronary heart disease.
