Which condition involves the brain not fully acknowledging images from one eye?

• A. Lazy Eye
• B. Pterygium
• C. Black Eye
• D. Diabetic Retinopathy

Answer: (A)

Amblyopia, commonly called lazy eye, is when the brain doesn’t fully process images from one eye. This happens because the two eyes don’t send equal signals to the brain—often due to the eye being misaligned (strabismus) or having a different refractive error than the other eye. To avoid confusion or double vision, the brain may start ignoring input from the weaker eye, so that eye develops poorer vision even though the eye itself is healthy. The result is reduced visual acuity in that eye, which often doesn’t fully improve with glasses alone and needs treatment to encourage use of the weaker eye. Treatment focuses on forcing the brain to use that eye again—commonly with patching the stronger eye or using penalization—along with correcting any refractive error and addressing misalignment if present, ideally started during childhood. Pterygium is a growth on the conjunctiva, a black eye is more about trauma, and diabetic retinopathy is damage to retinal blood vessels from diabetes, not a brain suppression of input from one eye.
