What Is Amblyopia?
Strabismus: When the eyes are not directed to an object at the same time.
Anisometropia: (an-i’-so-me-tro’-pe-a): A difference in the need for glasses between the two eyes.
Astigmatism: Unequal focusing of light rays as they enter the eye, causing a blurring of objects.
Media opacity: An object that prevents light from entering the back of the eye.
