I think it was because I really wished I HAD to wear glasses for some reason. I just liked them. I thought I could hide behind them.
Now I DO have to wear glasses or contacts and wish I didn't [emoji14]
I have only started wearing reading ones myself for a few years but do feel a sense of being more insulated. I think people can't see my eyes so easily - what I am or am not looking at - Not quite completely hidden, but ducking a little maybe. It also seems to heighten the sense of being focused, when I am working on something.
Contacts though I could never do I think. I can't manage to even touch my own eye. I can't stand anyone else touching it either. Eyes aren't supposed to be touched. Once I got a tiny sliver of metal in one firing a rifle. The medic pulled the splinter but not before I managed to get a rust ring in the eye. Then a specialist told me to hold my eye open and head still so she could buff it out with a dentist type drill. I was like, 'wait aren't you gonna clamp my head in a vice or something?' They said 'No. You won't move.' I was like 'I.. don't know if that's strictly true!'
