Vitamin A, also known as retinol, is an important nutrient that is vital to the health of your eyes. It helps produce rodopsin that is necessary for dark adaptation. It helps maintain the natural structural integrity of the cornea, retina and other eye tissues. Vitamin A deficiency may lead to numerous ophthalmological disorders especially xerophthalmia and night blindness.
Xerophthalmia is a serious condition of eye that might lead to blindness. This disease affects the cells of cornea and tear ducts. Night blindness makes it nearly impossible to see in relatively low light. This condition occurs due to inability of retina to respond to the light due to vitamin A deficiency.
The rich dietary sources of vitamin A are fish, fish oils, liver, nuts, fruits, vegetables and dairy products. These food items contain carotenoids which are converted into retinol by your body.
It also makes a good idea to use a dietary supplement that contains vitamin A in its formulation. BioCare One-A-Day Multivitamins & Minerals with Lutein & Bilberry is a popular brand on the market that makes an effective broad spectrum, antioxidant and one-a-day multinutrient tablet. It contains vitamins A, B-complex, C, D, and E, minerals, and additional antioxidant support from beta carotene, lutein and bilberry. Vitamin A helps maintain the health of your eyes and skin. B vitamins help release energy from food and boost your immune system. Vitamins C and E act as antioxidants and help destroy free radicals in your body. Vitamin D strengthens your bones and helps absorb calcium. Take one tablet daily with food.
