You do look like your are squinting in these photographs.
How about posting photos where you are not squinting? You may have ptosis. It is hard to tell in these photos. I recommend seeing a fellowship trained, aesthetically oriented oculoplastic surgeon for an assessent. The American Society for Ophthalmic Plastic and Reconstructive Surgery maintains a regional directory on their website that will help you find a highly qualified surgeons to assess your concerns in a personal consultation.
Is this ptosis?
Sorry, but your photos are somewhat suboptimal to render an exact opinion. You do have narrow palpebral fissures, so that can be defined by ptosis depending upon racial variants. If it is troubling you then there are surgical procedures that can repair ptosis of the eyelid(s). Generally, oculoplastic surgeons perform the most eyelid ptosis surgeries. Those that are fellows of the American Society of Ophthalmic Plastic Reconstructive Surgery have had extensive post-residency training in eyelid plastic surgery-both cosmetic and reconstructive. Best regards.
Eyelid asymmetry, ptosis?
A more detailed photos and extensive clinical exam is needed to give you relevant opinion about your condition. You should seek a consultation with an experienced oculoplastic or board certified plastic surgeon for detailed evaluation and discuss your options. Good luck.
