Summary Introduction

To determine:

The effect of vitamin A deficiency in the vision.

Concept introduction:

Vitamin A is essential in synthesizing the visual pigments in the eyes, which helps in differentiating among the colors. Vitamin A is also called as retinol. The body stores reserve of the vitamin A so that the retina is replenished with discs of visual pigments as soon as it exhausts.
