Amblyopia is characterized by decreased vision in an anatomically healthy eye that fails to send correct visual signals to the brain.
This is because the eye and brain do not work well together during early development. The eye is, as it were, “switched off” by the brain, which prefers the other, better-seeing eye.
Amblyopia is preventable or correctable in most cases, provided the underlying cause is treated before the age of six. Early detection and treatment are therefore essential for good visual development.
