If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.

Such an app, for Windows: https://justgetflux.com/

Been using it for several years. I actually have the filter on all day because I find the reducing the blue light is much easier on my eyes. Mr wtg doesn't use it, and when he logs onto my laptop under his user ID I'm like "My eyes! My eyes!"

There is also a blue light filter setting on Apple devices like the iPhone and iPad:

I'm a firm believer in trusting ones own bodily responses (I used to religiously follow online advice especially when it's as universally repeated as this one about blue light).

That said, I've always loved blue light at any time of day but especially at night. In Haifa I always turned on a blue nightlight at bed time, and it was part of the bedtime ritual my son and I followed.)

Accordingly, I refuse to follow this particular instruction about health and sleep because it's simply not how my brain physiology works. In fact, red or other warm lightwaves disturb me.
I wish "they" weren't so dogmatic about this - makes me feel delinquent when I put a blue tint on my laptop screen when I watch some Netflix serial before falling asleep. (I always DO reduce the brightness considerably.)

(I know watching such a thing is also forbidden!)

For me, it puts me right to sleep. (I sleep with my laptop - thanks to a large mattress I can avoid damaging it). The next day I have trouble finding where I was in the plot because I go into a semi-conscious state while it's still going. THAT's instead of reading!

SO shoot me.

Lol.
