What condition denotes poor correctable vision without physical abnormalities?

Amblyopia is a condition characterized by poor vision in one or both eyes that is not due to any physical abnormalities of the eye itself. This condition often arises during childhood when the brain and the eyes are not properly aligned, leading to a lack of visual communication between them. The brain begins to favor one eye over the other, which can result in reduced vision in the weaker eye even though it appears physically normal.

Unlike conditions such as astigmatism, hyperopia, or presbyopia, which involve specific refractive errors or aging changes in vision, amblyopia specifically relates to the brain's processing of visual information rather than any identifiable structural issues. It is important to note that amblyopia can often be treated effectively with early intervention, such as corrective lenses, patching, or vision therapy, to help improve the visual capabilities of the affected eye.
