You aren’t missing much.

Maybe they don’t want those divots in the side of their nose? But it might be more in line with being nervous about Lasik or something, which I get because I haven’t gotten it because 1) I don’t have the money and 2) my understanding is that they cut into your eye so a flap of it is just there. If someone were to punch me in the face after, it might be easier to pop my eye! I haven’t looked much deeper into it, but that’s my, maybe irrational, fear. Apparently the better surgery to get is one where they grind down your eyes to have better lenses, but that seems like a huge thing also, probably more expensive, and it would take a long time healing from it while essentially being blind.
