which words to use to describe the sight problems in our eyes? When we don't see and we need glasses to see

Question

also the others? Please, do help me out. Also when a person has crossed eyes. Is that ok to say so?

Answer 1

If you can't see things that are far away, you can say " I'm short-sighted for British English and near-sighted for American English"

If you can't see things that are near to you, you can say " I'm long-sighted (BrE) and far-sighted (AmE)

"Cross-eyed" is an adjective, but the noun is "squint". So a person is cross-eyed, and that person has a squint. I think it's ok to say these two words.

Colour blind is the word you can use if you can't see some or all colours

Answer 2

It depends what kind of eye sight problem you have. There are so many different terms that you can use depending on the problems you have. Here is a website that might help you with the terms http://library.thinkquest.org/C005949/glossary.htm

Answer 3

Emmetropia = normal vision
Myopia = nearsighted, we see things up close but distance is fuzzy
Hyperopia = farsighted, we see things in the distance but close objects are fuzzy
Presbyopia = literally, old vision, where the lens becomes less flexible and we cannot focus as well to read.
Strabismus = deviation of an eye
Exotropia = outward deviation
Esotropia = inward deviation
