Lutein and structurally related carotenoids are known to accumulate in the eye, where they can buffer light and protect underlying retinal cells from oxidative stress. Lutein helps in suppressing inflammation and defending against free radicals. It enhances the sharpness, reduces glare impairment and improves your eye health. It prevents age-related macular disease which is the leading cause of blindness and vision impairment. Zeaxanthin shields to protect the eye cells from the harmful effects of certain light sources, such as the sun, UV etc. It also protects the eyes from dangerous free radicals that form over time from oxidation and reduce cell loss and death related to eye disease. Astaxanthin prevents dry eyes, reduce eye strain, eye fatigue and increases blood flow to eye tissues which improves focus.
