I got glasses when I was 14 too. :)
Well, obviously you can use glasses or switch to contact lenses - I recommend having both as long as you feel you're responsible enough. With owning glasses, you don't need to do much! Wear them if you need them, keep them in a case when you don't - and if you need them 24/7 then just have somewhere safe and accessible to put them when you sleep! Also, keep a microfiber cloth in the case for lens cleaning purposes. Lastly, go for cheaper frames and get the scratch-resistant laminated coating.
Oh, and if you're still required to wear a mask in school, make sure it makes a good seal around your nose or else they fog up lol.
I say all of this but jsyk I do not practice what I preach.
