Carrots contain large amounts of carotene, a precursor of vitamin A. Can eating carrots help improve blurred vision from myopia or hyperopia? Explain. Also, explain how eating carrots may influence scotopic (night) vision.

Solution

Answer: Myopia is mainly due to vitamin-A deficiency. Carrots contain large amounts of carotene, a precursor of vitamin A. Yes, eating carrots can help improve blurred vision from myopia or hyperopia. Carotene improve the synthesis of Vitamin A is a fat- soluble vitamin by promoting retinal synthesis from beta-ionone rings so that it is possible to generate pro-vitamin A that brings retina to function properly by avoiding retinal detachment. Eating carrots may influence scotopic (night) vision by promoting synthesis of retinal pigments and retinoic acid. Therefore, it is possible. Therefore, the collected signals from the rods, and cones of each eye with \"retina associate with retinoid acid\" and finally transmit those signals to retinal layer of eyes where ganglionic cells are located. These ganglionic cells often transmit signals to visual cortex. There are two types of cells such as on-center cells and off-center cells. Normally ganglionic retinal cells receive visual information form rods & cones through bipolar cells & amacrine cells finally transmit to thalamus, hypothalamus and visual centers.

We find two types of vitamin A in our foods namely retinoids and pro-vitamin A. Retinoids (retinol, retinal and retinoic acid) are present in food sources of animal’s origin and it is the active form. Beta- carotene (a type of pro-vitamin A) is commonly present in vegetable and plant food sources.
