We’re all independent matures who work in front of a computer all day long, and entertain ourselves using gadgets when time allows. High-power spectacles are no surprise. But you’re lucky if you still haven’t got prescribed spectacles.

However, things don’t always remain the same. One of the most promising benefits reaped from Vitamin A is its significance in preserving good vision. It is necessary for optimal retinal function and the generation of vision pigments. In the eyes, a type of vitamin A known as retinal combines with a protein known as opsin to generate rhodopsin, a light-absorbing molecule required for color vision and seeing in low light. A deficiency in vitamin A leads to increased peril of severe infections, numerous health issues and pathological conditions, including eye disorders, such as night blindness, corneal drying, keratomalacia, and other age-linked vision health issues.

Even though your body has its own army, you must keep it strong. Apart from treating impaired vision, Vitamin A plays an important role in immune system support and its deficiency can lead to an impaired response to infection.

Recent multidisciplinary investigations have improved our understanding of the link in the middle of vitamin A and the immune system. Studies have found that it aids in the production of white blood cells which in turn acts as a shield and protects our body from any invasion of infections or germs. Furthermore, vitamin A is essential for the formation and function of white blood cells, which improves the body’s ability to action infections.

Cell growth and development:

One form of Vitamin A, retinoic acid, is a key hormone-like growth factor for various cells in the body. It affects gene expression and influences cell specialisation, particularly in skin and epithelial linings. As a result, it is required for appropriate development during pregnancy and childhood.

As an antioxidant, vitamin A aids in the protection of your cells against the effects of free radicals — molecules produced when your body breaks down food or is exposed to tobacco smoke and radiation. Free radicals can cause cell damage as well as contribute to ageing and health issue. Research shows that Vitamin A promotes overall health and may help avoid chronic health issues by countering oxidative stress.
