An eye condition where images seen by each eye are noticeably different in size, making comfortable binocular vision difficult.
From Greek 'anisos' (unequal) + 'eikon' (image) + '-ia' (condition). This ophthalmological term was formalized in the 20th century.
Anisoiconia is a visual puzzle your brain struggles to solve: if one eye sees a bigger version of reality than the other, your depth perception gets confused and you might experience dizziness!
