There are many things you can do to keep your eyes healthy. In addition to regular eye tests and wearing sunglasses outdoors, eating a good diet can be a factor.
You would have heard that carrots benefit eye health, but you might not know why. Carrots contain a class of compounds called carotenoids, in particular beta-carotene. Beta-carotene can be converted by your body into vitamin A, which is particularly important for maintaining healthy vision.
Getting vitamin A in the form of carotenoids has advantages over taking preformed vitamin A (retinol). Excess preformed vitamin A (retinol) can have significant toxicity; however consuming large amounts of carotenoids found in vegetables is not associated with adverse health effects.
Zinc and riboflavin also help in maintaining healthy vision.
If you’re cooking with frozen vegetables, don’t defrost them first as this will reduce the amount of vitamins available to you.
