Vitamin A is one of the most important vitamins we can take to maintain eye health and to benefit our vision. It has two main functions; assisting the normal function of the retina so we are able to detect light and helping the eye create tears. In fact recently developed eye ointments and drops include Vitamin A. Research is underway to determine whether it can also improve degenerative eye conditions. Sustained vitamin A deficiency which is more often a problem in developing countries, ultimately leads to Xerophthalmia which is when the eye is devastatingly dry due to low or no tear production. This can ultimately result in scarring on the eye and total blindness.
Did you know that Vitamin A absorption into the body is improved when combined with sources of Vitamin C, D or E, Zinc, Vitamins B2, B3 and B12, or Iodine. By boosting your daily intake of Vitamin A with foods such as: Cod liver oil, butter, whole milk, egg yolks, chicken livers and kidneys, you can guarantee you and your eyes will benefit.
