Similar to a camera lens, beams of light hit the eyes and become focused to help us see images. When this happens correctly, the images are transmitted to the brain to provide a clear and focused vision. When there is interference, problems with vision can arise such as nearsightedness.
In medical terms, nearsightedness is called myopia, and it affects 30 percent of the United States population. Here’s a look at the symptoms, risk factors and treatment methods available for myopia.
Myopia is the inability to see objects clearly when they’re too far away. People with myopia can often read or see items within a few feet of their face, but distant objects appear blurred.

There are several treatment options for myopia:
