I have -0,75 on both eyes and wear glasses to lectures etc. only. I feel like it's getting worse lately tho, so yeah.

Probably.

My eyesight has been getting progressively worse every year for the past 5 years I got glasses last year but I never wear them, I really should because I can't read anything unless it's literally right in front of me I swear if it keeps deteriorating at this rate I'll be blind before I'm 20

Omg this I sound like an idiot and you can't really explain that you can't see it
