My eyes are uneven, why is that? Is this normal? (Photo)

Yes, facial asymmetries can be corrected.  In most cases, obvious asymmetry between the sides of the face is due to differences in the facial skeleton. A bit of facial asymmetry is completely normal. Facial fillers or facial implants can be used to correct this type of asymmetry. I recommend you seek a professional consultation with a Facial Plastic Surgeon to see what your options may be. 

An ophthalmology or oculoplastics consultation would help you. In this photograph the left eye appears to be looking downward slightly (left hypophoria or hypotropia). An ophthalmologist or oculoplastic surgeon will check your vision, ocular movement, ocular alignment, as well as eyelid and orbital measurements. Many individuals have a phoria, a tendency of one eye or the other to "drift" when not fusing. The eyes may drift outward (exophoria), inward (esophoria), upward or downward (hyperphoria/ hypophoria). This drifting may not cause clinical problems and may be considered within normal range. If a misalignment ("strabismus") is associated with double vision, it can be treated or repaired. The most accurate advice will come from an in-person evaluation. Best wishes.
