This condition is commonly called “lazy eye” and occurs when one eye develops differently than the other eye. This causes one eye to be weaker than the other. Often times the two eyes cannot function together because of one being too weak. Most times the patient with Amblyopia causes one eye to do most of the work in seeing. Other times, the eyes are misaligned, causing one eye to totally “shut down” to avoid double vision issues. Regardless of the cause, the result is a weakened eye.
