How Do Contact Lenses Correct Myopia and Alter Near Point Vision?

In summary, myopia, also known as nearsightedness, is a refractive error caused by the eyeball being too long or the cornea being too curved. It is believed to be a combination of genetic and environmental factors. Myopia can be diagnosed during a routine eye exam and managed through wearing glasses, contact lenses, or undergoing refractive surgery. If left uncorrected, myopia can increase the risk of developing other eye problems.
