Answer 1

Answer:

Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry. It occurs when the shape of your eye causes light rays to bend (refract) incorrectly, focusing images in front of your retina instead of on your retina.

Answer 2

Answer:

Nearsightedness, the ability to see close objects more clearly than distant objects. Myopia can be caused by a longer-than-normal eyeball or by any condition that prevents light rays from focusing on the retina.
