Health Tip: Reasons for Crossed Eyes

(HealthDay News) -- Strabismus, or crossed eyes, occurs when one eye is turned too far in one direction. Symptoms often are evident at birth, and are usually corrected if treated by about the age of 5 months.

The University of Illinois Eye Center lists these common causes of strabismus:

• Heredity.
• High degree of farsightedness.
• Vision loss in one eye, usually a result of disease.
• Nerve damage to muscles in the eye.
