Beta-carotene is a precursor for Vitamin A, AKA 11-cis-retinol. Our body turns beta-carotene into retinol. Retinol is a precursor for opsin-11-cis-retinal, which you can think of as the molecule that absorbs the energy of a photon in a photoreceptor. When this energy is absorbed it eventually causes an electric signal to go to our visual cortex where we state, "I saw something!". Without vitamin A, or by being vitamin A deficient, this process does not work, and the cells that run this process stop functioning.

The amount of evidence that supports carrots (more specifically the large amounts of vitamin A in carrots) being good for your eyes is, well, overwhelming. Real science supports that statement going back many decades, millions of experiments.

If you have evidence that supports a different theory, that proves all of that evidence as fraudulent, please present it. Outside of that, making such blanket statements without evidence only causes confusion, and you become a source of disinformation, which helps no one.

Not to place blame; we all do it to some extent, but in this case there is substantial evidence that you are incorrect. When making such controversial statements it is best to provide your evidence along with it. At the least it provides context and gives someone something to look up. It also provides a starting point for people to engage their own critical thinking skills in the never-ending quest for truth.

Knew that one! It's probably one if the most successful propaganda campaigns next to "thank you for your service"
