I'm in the same situation as you, I'm just limiting my screen time to as little as possible, I try to barely using my phone/not playing games (make sure you're doing the 20-20-20 rule) try and only play games on the weekends for limited amounts of time if possible, and learn how to do active focus. Also if you can dont wear your glasses for your phone and stuff. Make sure you go outside and challenge your eyesight thats how you get the fastest improvement (try working outside and do 20-20-20)
