Blurry vision, which is a change in an individual's vision that makes images appear fuzzy and unclear, is quite common. In fact, millions of individuals around the world suffer from blurry vision. This can come on quite quickly or over time, and it can also be in only one eye or both eyes. Besides the standard factors that typically cause an individual's vision to blur, such as aging or staring at a computer or television screen for extended periods, or even just feeling quite tired, blurry vision may be an indication of a more severe issue requiring prompt medical treatment before serious complications set in.

Nearsightedness, otherwise known as myopia, is one of the most common vision issues in the world. Nearsighted individuals can see the objects close to them, but objects far away become blurry. This condition occurs when the eye's shape causes incorrect refracting of light rays. With normal vision, the rays focus on the retina, the light-sensing portion of the eye. This allows the eye to make out details and focus on objects. But in nearsighted individuals, light rays focus in front of the retina rather than directly on it. Nearsightedness often runs in families. It can develop on a gradual or rapid basis, and it tends to become worse during childhood and the teenage years. Nearsightedness can be confirmed through a basic eye exam. The vision blurriness individuals with this condition experience can be corrected with prescription eyeglasses, refractive surgery, or contact lenses.
