Is this ptosis? I've had uneven eyelids my whole life; the extra skin can feel irritating and makes my face asymmetrical (photo)

Best to have personal consultation. Your eye asymmetry is likely due to multiple factors and there are several options available, including nonsurgical and surgical.

It doesn't look like you have a ptosis in these pictures.  You do have some asymmetry which appears to be some extra skin on the right side.  There are some excellent oculoplastic surgeons in your area who can evaluate your lids and determine what would be best to help you. 

Hello emefh7,
While your upper eyelids do appear to be asymmetric, it does not appear that ptosis is the major culprit. One way to diagnose ptosis, which is an abnormally low lid, is to measure the distance between your upper lid margin and the light reflex point on your eye when you are looking at a fixed point. This is called the MRD-1. You should see a plastic surgeon in consultation to have a thorough eye and eyelid exam to determine this measurement as well as other measurements of upper lid function.
Your asymmetry appears to be related to at least two factors: dermatochalasis, which is excess skin of the lid, and asymmetric supratarsal folds. These can be addressed with blepharoplasty surgery.
