What is "lazy eye"?

Robert K. Maloney (Ophthalmologist) gives expert video advice on: Are my frequent headaches due to vision problems?; What can cause temporary blindness?; What should I do if I lose my vision suddenly? and more...

If the eyes are misaligned or if one's turned in or turned down, the brain learns to ignore the eye that's pointing the wrong way because it's giving a confusing image. The brain actually disconnects the nerves that connect that eye. That condition leads to what we call lazy eye; the medical term is amblyopia. It esentially means that that eye doesn't see well. And unfortunately, that loss of vision is usually permanent because the brain just learns to ignore it.
