i sometimes switch to glasses when i've been using the computer a lot. Got glasses now?>>2882754
from what i've been told instead of just being at the good strength, my eyes have to compensate a bit, so it causes your eyes to be more tired in the evenings
and they mostly get worse as a teen from still being in development. and it's not because of contacts or anything, In my case it's genetics and too much screen usage, had the same while using glasses.
and contacts are easy to replace, so you can do it often to adjust to the eyes, but with glasses it's more expensive, so you don't replace the glass as often
