I'm short-sighted but not too horendously.
I can't see things that are far away from me, for example, whiteboards in classrooms and I have difficulty seeing small text that is a few feet away from me.
But I've only had the problem for about 3-4 years now.
I got glasses first when I was on the border of being 13, but I only ever wore them when I needed them, so, in lessons and things. I wouldn't wear them during lunch-breaks or at home normally unless watching the TV.
Then at about 14 I started to wear them more often. Partly because my eyes had gotten a littlebit worse and I now had stronger glasses and my optician had told me I should wear my glasses all the time to reduce how much my eyes deteriorate.
So, I started to, and then noticed not long after that my eyes had actually gotten worse without glasses, but it had only gotten so rapidly bad while I had been wearing glasses constantly.
So, wearing the glasses all the time sort of led me to have to wear them all the time.
Also, I was really annoyed with how rough and annoying people can be at school aswell as inconsiderate and would throw my bag around while it had my glasses or glassescases in there.
When I got a new pair of glasses that were rimless on the bottom, I decided I couldn't keep them in my bag at all because they'll get chipped to pieces.
So, I've been wearing them all the time since.
Unfortunately though, I find I look much better without glasses.
I'm not ugly with them on, and they give me a good look, but without them I have a better look.
