Do I have upper eye lid exposure? I think I have monolid, but there seems to be a high line on my upper lid

There is no substitute for a personal assessment. Do your homework and see surgeons who understand the Asian male eyelid.  If you have surgery, it is critical to have a crystal clear understanding of what is being proposed so their are no surprises.

Dear hungc1Thank you for your question and photos!  It is very difficult to tell the shape of your eyelids. If you could post a more detailed photo- that would help.With Warm RegardsTrevor M Born MD

As already mentioned, poor photos for critical analysis. That said, it appears that you have "monolid". If not, then the levator attachment is very weak (unlikely as there is no ptosis/droop)  and/or very high but I don't think either is the case. You look fine and I'd leave things alone. If you want an eyelid crease, then see a plastic or oculoplastic surgeon for review, advice and possible alteration to the eyelids that you wish to achieve.
