Root Explanation

Aniseikonia is formed from "ani-" (from Greek "anisos", meaning unequal) and "seikonia" (from Greek "seikōn", meaning to have or hold). The term describes a condition where there is an unequal perception of the size of objects, particularly in the context of visual perception.

Memory Tip

Think of 'unequal' ('anisos') to remember that 'aniseikonia' refers to a condition where there is an unequal perception of size.
