The myth says: carrots are good for the eyes, so you should eat many. In principle, this is also true: carrots provide beta-carotene, which the body converts to vitamin A. The photoreceptors need this vitamin in the eyes. A vitamin A deficiency would make it difficult to see at night.
The only thing is, in our latitudes, we take in enough vitamin A through food, so eating an overdose of carrots for the eyes is not necessary.
Myth II: Reading in dim light is bad for your eyes
Reading in dim light is harmful to the eyes, says the myth. And it is not right: Neither reading nor watching TV in low light leads to defective vision, and the eye can adapt to different light conditions. But: Due to the bad light, one must naturally exert oneself more when reading, whereby it can come in the drying out of the eyes and headache. So while your eyes don’t get worse, they may hurt.
Myth III: Glasses make the eyes lazy
Although the eye can compensate for farsightedness for a long time, the defective vision will have progressed to the point where glasses are needed. And then you should wear them; there is also no faster deterioration of refractive error – a myth.
