2. Causes of Amblyopia

Strabismus makes the eyes unable to align when looking at the same object. The straighter eye tends to become the dominant eye, maintaining a healthy connection to the brain, but this leaves the weaker eye unable to focus, wandering in, out, down, or up. Eventually, the eye that works properly takes over the work of both eyes. Various visual differences in a child’s eyes can contribute to amblyopia. Both eyes may be nearsighted, farsighted, or a combination of both, causing uneven focus. Eyelids that droop can cause amblyopia by blocking vision. A cataract can lead to amblyopia due to blurry vision in the affected eye.
