Lazy Eye

Lazy eye, or amblyopia, occurs when one eye does not develop normal vision, usually due to the brain relying more on the stronger eye. It can lead to reduced vision in the weaker eye if not treated early.

What is lazy eye?

Lazy eye, also known as amblyopia, is a condition where one eye does not see as well as the other. This can happen because the brain favours one eye over the other.
