It's good. I was born with a single eyelid and double eyelids. When I doze off occasionally, I look double eyelids. When I was in college, I was clamoring to cut my double eyelids, but my family has always been particularly opposed. Later, I worked, the economy was free, and my family didn't care so much about me. Last year, with the support of my boyfriend, I successfully cut the single eyelid of my left eye into double eyelids. Now it is natural and almost invisible.
