Myopia: What Is It?
Do you have problems seeing objects in the distance, such as highway signs, until you are just a few feet away, but you don’t have any issues reading a book close to you? More than likely, you are nearsighted, also known as myopic. This is a common condition that an eye professional can remedy with eyeglasses, contact lenses, or eye surgery.
What Exactly Causes Myopia?
The culprit is the structure of your eye. If your eyeball is too long or your cornea is too curved, the light that will enter the eye will be unable to properly focus. Images will focus in the front of your retina, which is the light sensitive area of the eye, as opposed to directly on your retina. This can result in blurred vision, which is also called a refractive error.

Your prescription assists the eye focus light on the retina, which helps to clear up the vision.
Eye surgery can boost your vision so much that you may not require glasses or contacts any longer. The two most common procedures for nearsightedness are as follows:
