An isometropia and Aniseikonia

Aniseikonia is the difference in image size perceived between the eyes from unstable magnification. The two most common causes are anisometropia and retinal pathology. Symptoms of presbyopia include diplopia, headache, dizziness, disorientation, and devilish eye strain. Aniseikonia is associated with anisometropia, as both anisometropia itself and the optical correction for anisometropia can beget presbyopia. In the terrain of anisometropia, presbyopia can affect from anatomical axial length differences, differences in photoreceptor distance between eyes or cortical acclimatizations, and can also be optically induced by spectacle or contact lens corrections for anisometropia.
