Lazy eye, also known as amblyopia, can be treated by wearing an adhesive patch over the stronger eye for months or weeks to stimulate vision in the weaker eye, according to the National Eye Institute. Wearing patches also helps develop parts of the brain associated with vision.
Prescription eye drop medication, such as atropine, can be placed in the stronger eye to blur the vision of the stronger eye and force the weaker eye to focus on objects, explains the National Eye Institute. Treatment for lazy eye in adults does not always produce a cure since the vision system develops primarily during the first seven to 10 years of a person's life.
Lazy eye, or amblyopia, is commonly caused by the eye's inability to focus as good as the other eye, states the National Eye Institute. The condition is more prominent in individuals who are more farsighted, more nearsighted or have an astigmatism. Lazy eye is also caused by cataracts or clouding that occurs at the front part of the eye. Lazy eye occurs when vision in one eye is reduced and fails to work properly with the brain. The eye typically looks normal, but the brain favors the other eye.
