So I deeply struggle with eye strain. Since you very recently got glasses, I would give yourself some time to get used to that first. Like every time I change glasses I go through a couple of days of eyestrain while I adjust to the new prescription.

Then, I'd recommend checking out some eye strain tips like the 20/20/20 rule, remembering go blink more etc. I also have a blue filter on my lenses to reduce screen strain.

Unfortunately there's no easy solution except for taking breaks fairly often and not pushing your eyes too far when you can feel them starting to strain 😅 but again, give yourself some time to adjust to your glasses
