Nearsightedness

When a person cannot see something from a far away distance, it is because their eyes focus incorrectly which causes the blurred vision. The clinical term for this is myopia, or nearsightedness. When light enters the eye it does not focus on the retina, but rather in front of it. This is what causes far away objects to be blurry. There are many corrections to this problem such as contact lenses, glasses, and corrective laser surgery to change the shape of the eye.
