Yes I do think I am spending alot of time on my computer screen and phone screen. Now I must wear glasses when I work on my computer and look at my phone for too long.
I do find myself using eye drops when they become red and dry. I also will reduce my computer brightness when my eyes start to hurt. I am hoping there is not some long term damage for those hours on my computer.
Technology does not stand still, our screens are not as harmful as they used to be. Yes, the devices on the market are highly differentiated, everything that is considered budget can still have a bad effect on your health. You've probably heard about pulse-width modulation, but you need to be careful with screens of this technology. Take care of your eye health, take breaks, reduce your load, and do all kinds of exercises. When purchasing devices, always pay attention to the quality of the screens.
