Two summers ago, I got a double eyelid surgery. I hadn't heard of ptosis before this. After the procedure, the doc mentioned that my eyes weren't "as big as he thought they would be" and mentioned that I may have ptosis, which is the first time I heard about it. Since I always wear glasses (which makes my eye problem unnoticeable), no one has ever said anything about my eyes, so I'm not sure if I have what would qualify at ptosis. I can't tell since asian eye anatomy is different.
