Vitamin A is essential for healthy vision because it maintains the integrity of cells in mucous membranes, including those in the eye. It is also needed for the synthesis of rhodopsin and other light receptor pigments in the eye. Without these, a number of vision problems occur, including poor dark adaptation (night blindness), xeropthalmia (abnormal dryness of the eye), keratomalacia (softening and necrosis of the cornea) and Bitot’s spots (foamy gray, triangular spots of keratinized epithelium on the conjunctiva).
