A big part of being able to research characters well is being able to break up the different parts so you know what you're looking for.

I'm going to use Kadia as an example and go back to the discussion on eyes and such we were having.

One thing you would want to look to do is justify any abnormalities in their appearance. Hers being the eye. There are a few things that can cause differently colored eyes. Fewer that would cause such a drastic difference. Since you've been specific about the albinism, you'd want to look into the different types there are to get a proper feel for what you should do, and what is just stereotyping. You could start looking into Wiki for information, but really your end goal should be to find articles made for people dealing with the topic at hand, and not just research purposes.

My character with the same idea, as I've said before, is a tetragametic chimera (link) so obviously my research for him went quite a bit into that, as well as the subjects you should be covering.

Articles detailing the vision problems faced by many albino people (such as this one) could be very useful to you, but a drawback with what you're going for is the complexity. It would only apply to the one eye, so further research should be done into the effects of diminished sight on one side. I went over some of the basic things before, but it would be worth poking around articles and maybe forums for more information.

Start with overviews for whatever it is you're researching, but by the end, you should be looking at articles/forums made for the people that deal with it (whenever possible), and NOT pages for awareness or for general lessons.

Realistically, she shouldn't have a pink eye at all, and the closer you get to that, the worse her problems with it should be. But. Artistic licence with characters is fine, so long as you can find a way to justify anything that has a purely aesthetic purpose.
