It made a huge difference for me. I suffered years of pain from a crinked neck, sore back, herniated gut, swollen leg veins, strained wrist (RSI), and dry eyes. Step by step, I solved the problems. (In matching order:) Higher monitors, standing desk, ergonomic chair, standing desk, better peripherals, dimmed screen (using f.lux). The key is gradually changing things until you find local maxima that work for you. If it hurts in a new way, change again. If the same hurt comes back, intensify the change. It’s not as simple as “too much screen time.” I spend far more time in front a screen now compared to before, and yet suffer far less.
