Amblyopia is the medical term for poor vision in one, or sometimes both eyes. Children are born with poor vision. As they develop the eyes send the message of what they see to the brain and the visual brain cells “learn” how to interpret these images. Over time the brain learns how to fine-tune the images it is receiving and the vision improves. If the image that is being sent to the brain is blurry then the brain will never learn how to see clearly from that eye. The important piece in this problem is that the brain cannot “learn” how to see clearly after a certain age (that age is not known for certain). We do know that the younger the patient is when he/she is treated the better the outcome will be. So, Amblyopia should be treated as early as possible.
