aniseikonia

A condition where the perceived size and/or shape of images differs between the two eyes. It can be caused by anisometropia (unequal refractive errors), retinal pathology, or optical factors such as anisophoria. Symptoms may include headaches, eye strain, dizziness, and diplopia. Treatment options depend on the underlying cause and may involve corrective lenses, contact lenses, or surgery. Measuring aniseikonia is important for determining the appropriate treatment approach.
