I just had to get my first pair of glasses.
Did you get vision correction glasses that help with reading or nearsightedness? 
nearsightedness! I can't see things far away :(
They make straps you can wear  so they don't fall off when you move or if you play sports.
Oh thats cool. I didn't know that, that's very helpful! 
Also if you only wear glasses sometimes, you can get a cord that goes around your neck so you don't lose them.
I think I've seen those. I need to get one because I'm always forgetting them places because I'm not used to having them lol.
You can also get safety glasses to protect your eyes from visible and near-visible light or radiation.
