I am not sure what these two words "farsighted" and "nearsighted" exactly mean. Is that right to use "farsighted" and "nearsighted" to describe hyperopia and myopia? Thank you for your answers.

Actually, this can be confusing especially if you are not a science student. I would give this code; hyper-more. That just the clue. The first response was correct.

I was confused about that before too, but now i'm not.. FArsighted people see things clearer if they are far away.. which is why they hold books many inches away when they are reading them.. While nearsighted people are the opposite, they see things clearly if the objects are near.. Both pretty bad conditions.

I think it's quite the right term to describe it This is the quote from everydayhealth.com : nearsighted have a condition called myopia, meaning the eye is longer than normal or the cornea curves too much, so light rays entering the eye hit the retina incorrectly. Nearsighted people can see close-by objects or print clearly, but objects that are far away appear blurred. farsighted have a condition called hyperopia, have eyes that are shorter than normal or their corneas curve too little. This means that light from close objects doesn't focus correctly on the retina, causing those objects to appear blurred, while objects farther away are seen clearly.
