They do contain Vitamin A and beta carotene, but you would have to eat a large, large amount of carrots to gain these benefits.

Carrots being helpful to vision is actually an urban legend started by the British RAF in WWII, they wanted to cover up their development of air radar. So, they attributed their amazing efficiency at spotting enemy planes to their pilots eating carrots.

Answer 3

For one thing, the vitamin A in carrots, prevents night blindness. If the vitamin A deficiency causing night blindness isn’t corrected, it can lead to xerophthalmia, with dryness in the eyes, corneal ulcers and swollen eyelids. Untreated, xerophthalmia can lead to blindness. In fact, vitamin A deficiency is the leading preventable cause of blindness in developing countries.

Vitamin A also prevents cataracts from forming and may have a role in preventing blindness from macular degeneration.

How much vitamin A do you need? The U.S. RDA (recommended daily allowance) for males age 11+ is 1,000 Retinol Equivalents (RE); the RDA for females age 11+ is 800 RE. Vitamin A is also measured in International Units (IU): 1 RE = 10 IU for plant products and 1 RE = 3.3 IU for animal products. If you smoke or drink, plan on taking in extra vitamin A, because tobacco keeps your body from absorbing it and drinking depletes what you already have in your body.

You can get vitamin A from two types of food sources: animal products that contain vitamin A (such as liver or butter) or plant products that contain carotene (you’ve probably heard of beta-carotene), which your body converts into vitamin A. Foods containing carotene are usually yellow/orange or leafy and green.

Answer 4

Of course carrots are still good for you (especially cooked carrots, since raw ones are mostly indigestible and just act as roughage).
carrots are rich in Vitamin A,which is used in the production of rhodopsin, the visual pigment used in low light levels. They contain beta carotene which is good for the eyesight. It improves the function of your rods and cones which are the part of the eye that perceives color. So actually your color acuity is enhanced.
carrots only enable gullible people to see in the dark.
