It's normal to have asymmetrical eyes, i.e., eyes that aren't the same level, size, or shape as each other. It often happens due to normal facial asymmetry and aging. However, in rare cases, asymmetrical eyes may be a symptom of an underlying medical condition. See an ophthalmologist if you're having vision problems or other symptoms such as eye pain, swelling, or a throbbing sensation in one eye. If the anomaly is associated with trauma involving the head or face, seek emergency care.
