I wear glasses. I have to wear them all the time, because I'm practically blind without them. Without my glasses, I can't tell the color of someone standing before me's eyes. It looks like blurred black blobs. XD;
I tried contacts, but my eyes are too dry for them. I tried solution designed specifically for dry eyes, and another and another, and I tried putting eye drops in my eyes but to no avail. xD; Besides, it wasn't worth the suffering just to avoid wearing glasses.
I don't have self esteem issues when it comes to glasses though. When I got them when I was in fifth grade, I was terrified I'd be teased. But I had really pretty frames, so all the girls told me they kinda wished they needed glasses so they could have something pretty like it too. xD; They meant it too, they weren't being sarcastic.
