Do you Know when to step away before screen fatigue hurts your health

I have been working in machine learning for the last 10–12 years on several personal and professional projects. For this, I have to use my laptop all day long. I have to write code, build models, deploy them into production, and talk with my coworkers. Some days, I do not even realize how quickly the day has gone by while sitting in front of my computer, even though I feel fatigued and sometimes have blurry vision.

I was wondering if you have also experienced this. If so, did you feel like you were pushing yourself to keep working when you needed to step away
