Detailed explanation-1: -Vitamin A supports functioning of the conjunctival membranes and cornea. 2 mg/day zeaxanthin Lutein and zeaxanthin, carotenoids, help neutralize oxidative damage as well as filter high-energy blue light reaching the eye, in turn reducing the risk of AMD and cataracts.

Detailed explanation-2: -Vitamin A is required for the maintenance of normal vision. A deficiency in vitamin A can lead to visual disturbances. In the eyes, a form of vitamin A called retinal is combined with a protein called opsin to give rhodopsin, an essential light absorbing molecule needed for color vision and seeing in dim light.

Detailed explanation-3: -Retinol that is circulating in the blood is taken up by cells in the retina, where it is converted to retinal and is used as part of the pigment rhodopsin, which is involved in the eye’s ability to see under low light conditions.
