Which vitamin is essential for good eyesight?

Answer 1

I don't know how vitamin A improves eyesight, but lack of vitamin A is the main cause (70%) of childhood blindness throughout the world, with 500,000 going blind every year due to lack of vitamin A. The amount of vitamin A required to prevent blindness is small.

Answer 2

None, really.

Vitamin A is chemically related to a pigment involved in eyesight, and is used in the body to make that pigment, but it's not so much "vitamin A makes your eyes work better" as "vitamin A keeps your eyes from not working at all."

If your diet is so deficient in vitamin A that your eyesight is failing because of it (note: we're talking actual night blindness here, not "I have trouble seeing tiny things a long way away"), taking vitamin A could result in some improvement. If your eyesight is more or less normal with respect to night vision, then vitamin A is not going to make it "better."

In particular, vitamin A has nothing to do with whether you need glasses or not. That's a purely physical matter having to do with the lens, and vitamin A is involved in the biochemistry of the retina.
