Aniseikonia is a condition in which each eye perceives a different image size or shape, creating distortion or discomfort. This mismatch disrupts binocular vision and can make objects appear stretched or unequal. Causes include unequal refractive errors, retinal disease, or post-surgical changes. People may experience headaches or depth-related strain. Proper measurement helps guide treatment.

Surgery that changes the eye's optical power may also introduce distortions. Some people develop aniseikonia after retinal repair. Identifying the source helps determine whether correction is possible.
People may notice objects appearing larger or smaller in one eye. Straight lines may look bent or uneven. Reading can become tiring due to constant adjustment. Headaches or dizziness may appear during binocular tasks. Depth perception may feel unreliable.
Testing involves comparing perceived image size between eyes. Specialized charts help quantify the difference. Retinal imaging identifies any structural causes. A refraction checks for unequal optical power. Combining these results helps build a treatment plan.
Treatment may involve optical adjustments such as size-matching lenses. Contact lenses sometimes reduce the mismatch better than glasses. Addressing retinal swelling helps when the cause is structural. Patients often improve with customized correction. Follow-up confirms comfort and binocular stability.
It depends on the cause. Some cases improve with correction.
Special lens designs can reduce image-size differences.
Yes. Many people experience strain during binocular tasks.
Seek care if distortion makes reading or depth judgment difficult.
