What Is Myopia (Nearsightedness)?
Myopia is a common refractive error of the eye that makes it difficult to focus on far away objects. People who are nearsighted will see objects close to them clearly, while those further away appear blurry.
Myopia is Natural
An overall longer shape of the eye usually causes myopia, so it is a naturally occurring visual problem that cannot be prevented. Nearsightedness tends to run in families, but you don't need to have a myopic parent to develop it. Myopia begins at an early age and worsens in the teenage years, but generally stabilizes in adulthood.
