Vitamin A is otherwise known as retinol, which is an intermediary to retinal. or beta carotene. When it is in the form of retinal, this metabolite will act as a light absorbing molecule.

Vitamin A is also an essential component of retanoic acid which is a crucial signalling molecule especially during Early Organogenesis.

It is necessary for low light and colour vision, as it is found in the retina of the eye. Vitamin A is used in the treatment of Rhodopsin-related diseases. 

A defficiency of Vitamin A is known to cause night blindness due to its essential role in the ocular system of the body [1][2][3].

Deficiency is more common within developing countries pariculary during infancy when they are not getting sufficient amounts in breast milk. Common symptoms include xerophthalmia, anaemia and increased susceptibility of infection[4].
