The difference in magnification can also be eliminated by a combination of contact lenses and glasses (creating a weak telescope system). The optimum design solution will depend on different parameters like cost, cosmetic implications, and if the patient can tolerate wearing a contact lens.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

When the image disparity is astigmatic (cylindrical) and not uniform, images can appear wider, taller, or diagonally different. When the disparity appears to vary across the visual field (field-dependent aniseikonia), as may be the case with an <a href="/wiki/Epiretinal_membrane" title="Epiretinal membrane">epiretinal membrane</a> or <a href="/wiki/Retinal_detachment" title="Retinal detachment">retinal detachment</a>, the aniseikonia cannot fully be corrected with traditional optical techniques like standard corrective lenses.
