Can you provide evidence of where screens cause damage to eyes? My ophthalmologist shared with me that there is general irritation but we haven't been able to prove that screen times degrade eye sight over time.

Staring at anything too close to your eyes for a long period of time isn't good for them. If you are taking appropriate breaks, my understanding is that screen time is harmless.

I've got the same understanding - I asked my ophthalmologist about it as well because my vision is already quite bad and I'm a computer engineer.

For breaks, she recommended the "20/20/20 rule" - focus your eyes on something at least 20 feet away, for 20 seconds, every 20 minutes of screen usage.

Yes, I've gotten that recommendation as well. Apparently more natural light exposure may also decrease the risk for nearsightedness. Having a window near my computer monitor makes it easy to remember to look outside whenever I'm not actively looking at the screen.

I think there is a nuance in reducing screen time versus increasing natural light exposure.
