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.
Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus at a point in front of the retina, rather than directly on its surface.
Currently, there is no cure for nearsightedness. But there are proven methods that can be prescribed by an eye doctor to slow the progression of myopia during childhood. ... But corrective lenses only work while a person is wearing them and they are not a cure.
