I turn down digital light for web browsing and create a custom profile for it.

I set brightness to 45 and contrast is set to 55.

Its different with different people and different monitors.

I have created a profile for movies which the brightness and contrast is set higher.

On my smart phone I have the brightness set at less than 20 percent and it stays at that unless I’m outside.

Monitor profiles make things easy.

I’m talking about blue light specifically. There are a lot of “digital” lenses about now for spectacles with blue light filters in them. This research says they are unnecessary. Some previous research checked the blue light levels you can get from digital devices and it is waaaay lower than what you get from a blue sky outside.

The blue light may mess with your diurnal rhythms, which is why it is suggested you turn your phone off around an hour before the time you want to go to sleep.

Smart phones should have an up down button for brightness or an indoor / outdoor sensor that toggles it.

Here is the other, older paper.

I think I posted it back then (2016) when it came out.

Yes, I understand that

For eye strain on the smartphone I use a night reader that sets the background and text colour to something that’s more friendly

and I turn down the brightness to less than 20 percent

I find that makes a difference

If I start to get eye strain with reading its the paper kindle with reflected light
