I went because one eye was slightly uneven. This was several years ago, so I don’t remember exactly, but both eyes had double eyelids, and they were big eyes.
One eye’s double eyelid was a bit smaller than the other, so I had a kind of eye-correction procedure to balance the proportions. At first, though, the eye on the operated side kept closing halfway... I regretted it a little, but after several years, that tendency to close like before has decreased, so I’m just getting by ㅡㅡ;;;
