What do the terms nearsighted and farsighted mean?
A nearsighted person (myopia) has better vision generally up close without glasses or contacts compared to far away vision. The eye is longer than normal causing light to be focused in front of the retina causing blurry vision far away. A farsighted person (hyperopia) may see better far away without glasses or contacts compared to near vision without lenses. The eye is shorter than normal causing light to be focused behind the retina, causing blurry vision worse at near than far. A person that is very nearsighted or farsighted may not see well near or far without correction.
