What Has Caused my Eyes to Become Asymmetrical?

There are various causes of asymmetry between the two eyes including difference in upper eyelid position (droopy eyelid, eyelid retraction), lower eyelid position, eyeball position (bulging eye, sunken eye), and bony eye socket (orbit) asymmetry. The treatment depends on the cause. See video below for some examples and more details. See an oculoplastic specialist for evaluation.

        Some amount of asymmetry is the norm, but pictures or an exam would be necessary to evaluate your concerns.                                                                                                                                            Kenneth Hughes, MD                                                                                                            Los Angeles, CA

Slight asymmetries of the eyes are the rule rather than the exception. A photograph would be useful in determining whether or not surgical correction is warranted.

It is not uncommon to have some minor asymmetry between the eyes, and the face in general.  When there is an issue with more obvious asymmetry of the eyes, sometimes it can be due to the height of the eyebrow and sometimes it can be due to the eyelid, or both.  Pictures would help to be able to try and determine the cause in your instance.  I would recommend seeing an ophthalmologist (eye doctor) to have your eyes evaluated, although it's possible that a facial plastic surgeon, plastic surgeon, or oculoplastic surgeon could evaluate you as well.
