Nearsightedness, or myopia, as it is medically termed, is a vision condition in which people can see close objects clearly, but objects farther away appear blurred. Myopia occurs if the eyeball is too long or the cornea (the clear front cover of the eye) is too curved.
Beginning in the early to mid-40s, many adults may start to have problems seeing clearly at close distances, especially when reading and working on the computer. This is among the most common problems adults develop between ages 41 to 60. This normal change in the eyes’ focusing ability, called presbyopia, will continue to progress over time.

The surface of the cornea is shaped more like a football instead of round like a basketball and the eye is unable to focus light rays to a single point.
Crossed eyes, or strabismus, is a condition in which both eyes do not look at the same place at the same time. It usually occurs in people who have poor eye muscle control or are very farsighted. Six muscles attach to each eye to control how it moves. The muscles receive signals from the brain that direct their movements.
Nystagmus is most commonly caused by a neurological problem that is present at birth or develops in early childhood. Acquired nystagmus, which occurs later in life, can be the symptom of another condition or disease, such as stroke, multiple sclerosis or trauma. Other causes of nystagmus include:
