This question is directed to both people with albinism and anyone who knows people with albinism (Or a doctor, I guess). As far as I can gather, albinos, for the most part, have poor eyesight, which comes both from improper eye development and lack of pigmentation. Question is, is this a 100% inevitable symptom of albinism? I've thought of a secondary villain for my novel, and his main shtik is that he's a deadeye marksman, but if albinism always means bad eyesight, then it wouldn't make sense for him to be albino.
He could, in theory, have replaced his eyes. That's a thing that can happen. Dunno what your setting is, though.
Just spotted that there's also what's called leucism, which doesn't affect the eyes. Problem is, I can't confirm humans can have that condition. Fantasy human leucism? Technically, I can make up whatever I want, I'm just trying to be accurate, and I really really want to have someone nicknamed Whitey.
Could be interesting if the villain simultaneously had bad eyesight, but nonetheless managed to train himself as an expert marksman. I imagine there are plenty of other factors that contribute to good marksmanship other than eyesight. Steadiness of aim, speed, understanding of how the wind will carry the missile, etc. (are we talking bows or guns here?) Would take research as to whether that's possible but if it is, that could make an interesting dimension.
It's a fantasy setting inspired by the early 18th century, so he'll be using a rifled musket. At the distances that he'll be shooting, blurry vision would make it almost impossible to know what or who he's shooting at. I'll go with leucism; it's got all I need to make the character stand out (And justify the nickname), and at the same time it doesn't affect his eyesight. And if someone says "but leucism is extremely rare in humans" or "it doesn't affect humans", I'll have the excuse of "it does in this world".
Ive known two people with this issue and both had glasses for very poor eyesight, one so much so that he was registered blind.
