What Could've Caused my Uneven Eyes?

Orbital dystopia refers to a difference in the set of the eyeball within the bony frame. We all have it if you look closely. Sometimes the bulgier eye tends to droop more quickly because of the unremitting pressure of the larger globe-like structure (the eyeball) on a weak lower eyelid.
In older patients (not you, you don;t need surgery for many years), we can perform a USIC(TM) (ultrashort incision cheeklift) to correct eye shape. There are three nice examples in the paper referenced below on how we can correct eye shape due to prominent eyeballs, prior surgery, or natural downgoing canthus (corner of the eye), none of which you currently have.
Don't let an aggressive unscrupulous surgeon prey on your insecurities and leave you with an altered appearance. I have seen it often enough.

Asymmetry between the two eyes can have various causes. Some of these causes include:
difference in upper eyelid positiondroopy eyelid (eyelid ptosis), eyelid retraction, etc. difference in lower eyelid positionreverse eyelid ptosis, eyelid retraction, etc. difference in eyeball positionsunken eye (enophthalmos, hypoglobus), bulging eye (proptosis, exophthalmos), etc. orbital asymmetryfacial asymmetryetc. 
The treatment  depends on what is causing your issues. You should see an Oculoplastic surgeon and Ophthalmologist for a complete evaluation. 

Facial asymmetries, especially around the eyes, are extremely common. Everyone has asymmetries to some extent. The main thing that is visible in the provided photos is some brow asymmetry. First of all, there is nothing that needs to be done about this unless the patient is very bothered by it. The brows can be lifted in order to improve symmetry, or Botox can be used to even out the brows, which is very quick and simple. Keep in mind that even with treatment, some degree of asymmetry is likely to persist and would be considered normal.
Be sure to see an expert.
All the best,

Examination of your photograph does indeed reveal that you have some minor asymmetry of your eyebrows, the periorbital soft tissues, as well as of the orbits themselves, although, in you, this asymmetry is significantly less than what we typically see in our preoperative patients.  Part of this fact can be attributed to your youth, and it is frequently the case that these asymmetries become more pronounced with aging, as increased sun exposure, changes in weight, decreases in skin elasticity, stretching and weakening of facial ligaments, and gradual resorption of the facial skeleton with age all contribute to exaggerating pre-existent facial asymmetries.In severe cases of asymmetry of the bony skeleton, craniofacial surgery can achieve significant correction.  Other less invasive surgeries, from endoscopic brow lifts to upper and lower blepharoplasties (eyelid surgery), to facial implants, to fat transfer can also be employed to diminish, although never completely eliminate, facial asymmetries.  In your case the degree of asymmetry you have noticed does not rise to the level of requiring any correction.  If one were to try to treat what you see in any way, a fraction of a unit or of botox applied above the lateral tail of one eyebrow and beneath the tail of the other would probably the most intervention that could be justified.  Finally, to address your last point, most people can only cock a single eyebrow, but many can learn to alternately cock one side and then the other, with sufficient training and practice.

You appear to have a very mild asymmetry from the photo, which is well within normal limits. There are several potential causes of ocular asymmetry, but without a close personal exam it is difficult to tell what (if anything) is going on here. I suggest you consult a PS with an interest in oculoplastic surgery if it is something that is worrying you. Good luck!

As surgeons we do a lot of facial analysis. If you do a split face analysis on any person with close inspection they will ALL have symmetries. It is part of life. These asymmetries increase with age.You are exactly right that part of the reason is difference in muscle tone and strength. Some of this is causes by environmental issues such the left side of the face receives more sun when we drive. I had a patient that was a truck driver and it was marked how different his facial aging was because he constantly had more sun on the left side of his face because as a driver in the US that is where the window is. Photography can also be very deceiving. Even the smallest angle of the chin can make a marked difference in the way light and shadows are displayed in the face. So make sure you use a good camera and have the proper angles if you are going to be critical. Chronic contact use has been shown to weaken and lengthen the muscles of the eyelids. This is most notable as a cause of lid ptosis. You would need a physical exam to determine this as it is a dynamic process to be tested.Overall you are an attractive young man and I would recommend embracing your good characteristics (great skin, full hair and good bone structure) and accepting these minor asymmetries. Hope this helps,Best of luck.DrC
