Amblyopia, commonly known as "lazy eye," is a vision disorder that is caused by the eye and brain not working together properly. It results in decreased vision in one or both eyes, caused by the eye and brain not working together properly. Amblyopia is usually treated with vision therapy, glasses, and patching therapy. Vision therapy can help improve eye tracking, eye teaming, and focusing skills. Glasses can help improve vision by correcting refractive errors. Patching therapy is used to cover the stronger eye, forcing the weaker eye to work harder and become stronger.
