VITAMIN A Physiological Role. As previously mentioned, vitamin A is essential to vision. Within the photoreceptor cells of the retina are the rods, which detect small amounts of light and are specialized for motion detection and vision in dim light, and the cones that are specialized for color vision in bright light (11).

Vitamin A Vitamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Retinol, the form of vitamin A absorbed when eating animal food sources, is a yellow, fat-soluble substance. 2  Since the pure alcohol form is unstable, the vitamin is found in tissues in a form of retinyl ester. 3  It is also commercially produced and administered as esters such as retinyl acetate or palmitate.

Vitamin D and Its Effects on Eyesight Vitamin D and Its Effects on Eyesight. An eye doctor trying glasses on a patient. It has been estimated that the complex system that enables eyesight requires about 30 percent of a person’s oxygen intake and 25 percent of their nutritional intake. Thus, healthy eyesight depends on essential nutrients, such as vitamins. Vitamins A, C and E are antioxidants that have been well-established as preserving eyesight and promoting healthy eyes, but evidence suggests vitamin D is associated with reduced risks of macular degeneration.

The Mechanism for Vitamin A Improvements in Night Vision Next, light must travel through ten layers of the neural retina to get to the rods and cones.1 The rods and cones are made up of an inner segment that contains the nucleus and an outer segment that is made up of discs that contain light-absorbing photopigments.1 When comparing the two photoreceptors, the rods are useful for night vision and the cones are useful for day vision. Vitamin A is one of the required precursors for the formation of rhodopsin, the photopigment found in rods.

vitamin A deficiency Definition. Vitamin A deficiency exists when the chronic failure to eat sufficient amounts of vitamin A or beta-carotene results in levels of blood-serum vitamin A that are below a defined range. Beta-carotene is a form of pre-vitamin A, which is readily converted to vitamin A in the body.Night blindness is the first symptom of vitamin A deficiency. Prolonged and severe vitamin A deficiency can produce total and irreversible blindness.eta-carotene is a form of pre-vitamin A, which is readily converted to vitamin A in the body.
