Haven’t heard of blue light blocker glasses. My wife and I put in red led bulbs for our nightstand lights and read paper books or magazines for about a half hour before going to sleep. I also do legs up the wall for about 10 minutes right before going to sleep and that really helps me.

How does red light help sleep? I googled just now, saw some stuff, but interested to see what you think or know.

more red signals sunset to the brain. Read in the HN comments that bunks in the navy are equipped with red lights so one person can read without disturbing the sleep of others.

Thanks, and will check those comments.

The glasses are about ten bucks on Amazon. I use a pair, but I found that dimming the lights is also important.

I think regularly indoor lighting while reading is fine, it is screens that become the real problem. So many people I know lay in bed reading their phone.

i dont think a kindle counts as artificial light, could be wrong though.

It does and using it in a dark room is worse than having background light. Fully avoiding artificial light after 8 is quite difficult but limiting blue light and bright light is easier.

Candles are nice. But anything is better, than ordinary LED light..

Can confirm, found ~2 beeswax candles (dunno if other materials are different brightness) is perfect for reading and getting about the house. I've been looking for a < 5 candle power battery incandescent-bulb lamp, but haven't found one. May have to build it. Candles are expensive (unless you get the stinky petroleum ones), inconvenient[0], and a bit of a fire hazard.

Once you get used to a couple candles carried (per person) and maybe one in the room for general illumination—which only took me a couple days—electrical multi-room illumination at night seems irritatingly bright and kinda insane. Sort of like when you cut out soda and then try one after a while and are put off by how cloyingly sweet it is.

[0] I wouldn't do it again without a shaded candle holder, for instance, otherwise you end up looking at them by accident all the time which is painful when your eyes are adjusted for low light. Would probably need to bump up to three candles to account for the shade.

I found red LEDs with USB power (so <2.5W) to be pretty good. They are available for decorative purposes.

Since I haven't replaced my Kindle I do all my reading with a dim red headlamp. I like it better than the paperwhite blue-white light and wish Amazon offered a red light Kindle.

Get blue light blocker glasses and it'll help a lot. Avoid backlit devices as they're the worst.

You don't have to go to bed at 8, just don't stay in bright light at least a few hours before you want to fall asleep.
