What is Strabismus?

Discover what visual aid suits your eye condition best

Strabismus is an eye condition in which the eyes are not aligned properly and point in different directions. One eye may look straight ahead, while the other may turn inward, outward, downward or upward. The manner in which the eye turns may be consistent or it may vary. Which eye is straight and which eye turns may also differ.


Strabismus is most often caused by a disorder of the brain in its ability to coordinate eye movement. It can also be caused by a lack of power or direction of motion in the eye’s muscles.


There are several types of strabismus, depending on the movement of the eyes and the age at which strabismus is acquired. Most cases develop during infancy. If a child’s eyes are not properly aligned from the age of four months, it is recommended to request an eye exam. Your doctor may refer you to an eye care professional.
