What ocular condition might anisometropia lead to if not corrected?

Anisometropia refers to a condition where there is a significant difference in the refractive power between the two eyes, which can result in unequal focus. If left uncorrected, this disparity can cause one eye to work harder than the other. Consequently, the brain struggles to merge the dissimilar visual inputs from both eyes, which can lead to double vision or diplopia.

In cases of untreated anisometropia, the brain may also start to ignore the input from one of the eyes to avoid confusion, which can result in amblyopia, commonly known as "lazy eye." This further emphasizes how critical it is to correct anisometropia to prevent such complications. Anisometropia does not directly lead to conditions like night blindness, color blindness, or glaucoma, making double vision the primary concern when anisometropia is not appropriately addressed.
