You mean to tell me they are not?!! I remember reading that carrots have some nutrient necessary for good eye sight, beta-catorene I believe. I don't think it improves your current eye sight so much as it keeps it from going bad from a lack of it.

Yup, actually carrots are good source of beta-carotene / Vitamin A which is necessary for good eye health and vision. Obviously carrots aren't the only source though.

"Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision.[2] Vitamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule[3] necessary for both low-light (scotopic vision) and color vision."

it's got a grain of truth to it, so it's a believable smokescreen

So getting sufficient vitamin A from carrots or other sources is instrumental in keeping your eyes healthy. That's not the same thing as saying that eating additional carrots will give you super-vision.
