Nearsightedness (myopia) is a common type of refractive error 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.
Nearsightedness may develop gradually or rapidly, often worsening during childhood and adolescence. Nearsightedness tends to run in families.
WHAT CAUSES MYOPIA?
The structure of your eye is the most likely the factor. When your eyeball is too long or the cornea — the protective outer layer of your eye — is too curved, the light that enters your eye won’t focus correctly. Images focus in front of the retina, the light-sensitive part of your eye, instead of directly on the retina.
Nearsightedness symptoms may include:
Blurry vision when looking at distant objects
The need to squint or partially close the eyelids to see clearly
Headaches caused by eyestrain
Difficulty seeing while driving a vehicle, especially at night (night myopia)
An eye exam can show you if you’re myopic. Glasses, contacts, or refractive surgery can usually correct the problem.
