The vitamin is needed to convert light that hits your eye into an electrical signal that can be sent to your brain.

In fact, one of the first symptoms of vitamin A deficiency can be night blindness, known as nyctalopia.

Night blindness occurs in people with vitamin A deficiency. As the vitamin is a major component of the pigment rhodopsin.

Rhodopsin is found in the retina of your eye and extremely sensitive to light.

People with this condition can still see normally during the day. But have reduced vision in darkness as their eyes struggle to pick up light at lower levels.

In addition to preventing night blindness, eating adequate amounts of beta-carotene may help slow the decline in eyesight. That some people experience as they age.

Age-related macular degeneration (AMD) is the leading cause of blindness in the developed world. Though its exact cause is unknown. It’s thought to be the result of cellular damage to the retina, attributable to oxidative stress.

The Age-Related Eye Disease Study found that. Giving people over the age of 50 with some eyesight degeneration an antioxidant supplement (including beta-carotene) reduced their risk of developing advanced macular degeneration by 25%.

However, a recent Cochrane review found that beta-carotene supplements alone won’t prevent or delay the decline in eyesight caused by AMD.
