Nearsightedness is a common visual condition where nearby objects can be seen clearly, but distant objects are blurred. They occur when the shape of the eye causes the light rays to bend (refract) incorrectly, the eye comes together when the rays bend incorrectly (refract), and the eye comes together when they bend (refract). the bending of light rays (refraction). Nearsightedness can develop gradually or rapidly, and it often gets worse during childhood and illness. Nearsightedness generally runs in families.

A basic eye exam can confirm myopia. Blurred vision can be compensated by the use of glasses, contact lenses, or surgery.
