I don't know my new contact numbers but i used to wear -2.5 and -2.75 in my contacts so what would my glasses of been? if there's a difference i need to know because my eye sight got worse so i used -2.75 in both eyes but now my new ones one of them is -2.75 but the other is like 4 or 3? and i'm pretty sure both my eyes are worse than -2.75 because i couldn't see anything with either eye using them like closing one eye then the other still a blur so what do u think?
