Will plain red or orange lenses block blue light for sleep?

Just as the title says. Wondering of there is something special about lenses sold specifically as blue light blockers, or if any red or orange tinted lenses will do. Already have f.lux on the computer, but I get off work late in Tokyo and the walk/train ride home exposes my eyes to a ton of bright blue light.

I use red bulbs at home, and feel it really simulates sunset lighting and makes me sleepy fast!

That's awesome, thank you. So the big ugly Uvex orange safety glasses I use to watch TV at night work perfectly according to this chart. The Gunnars, as wonderful as they are for getting rid of eye strain do not block blue light. A pair of orange sunglasses I bought off woot a few months ago (Peepers brand) let in a little bit of blue, but not much.

Yellow or amber lenses will only block some of the blue light as I understand it but if indoors that may be all you can do while still being able to see clearly. If you know it will be very bright then copper lenses are recommended.

+1 I have a pair of those same glasses. I wear them an hour or two before bed time (when I remember to put them on) and they are effective in my opinion.

Yeah, I'm afraid that won't do with my suit in Tokyo. I'd never meet a girl again! I was going to get some cool frames like Gatorz bc you can get any color lenses you want. Otherwise some aviators. My main concern is do they actually BLOCK cool temperature blue light, or just enable you to look upon the world thru rose colored glasses, pun intended.

Why not? You might start a fashion trend!

Agreed on both counts: I have these and they work great and are super cheap, but you definitely don't want to be wearing them out and about.

I guess I'd feel rather conspicuous wearing them on a train or on the street though. In that case I'd probably go with some amber-lens aviators like driving glasses or something.

I've used these with good success, although I haven't tried the more expensive ones that are specifically designed for the purpose as a comparision. Many of the reviews for them are regarding blue light blocking however and you can't beat the price. They are not the most comfortable to wear but I can watch a movie or work on the laptop for a while and they are just fine.

Yes, there's a reason that the orange-amber tint color has been trademarked as "BluBlockers". Any optical store should be able to put some tinted lenses in a regular frame so you can wear them around without looking like a dork ;)

While not the same of orange and quite expensive Gunnar makes several kinds of glasses of that color and in much nicer frames. They do magnify a little bit so that might be an issue. I think it's +0.25 diopter or something like that.

See this thread as well: http://paleohacks.com/questions/527039/glasses-for-blocking-blue-light-at-night.html The color has nothing to do with blue-light blocking. To make sure whether the lenses can blue light effectively, you can use the spectrometer to detect. The eyewear(http://www.halovis.com ) I'm using is yellow that can block 97% of blue light. Check out this the video on YTB to see how it works: https://www.youtube.com/watch?v=nmUebEu3GzE

I've come to find the answer is no the hard way because the company won't give me a full refund. NOT all orange lenses block blue light. I recently bought a pair of shooting glasses (Radians Revelation Protective Shooting Glasses) with orange lenses and they do NOT block any blue light using the chart above. However, the Uvex (tried 2 different pairs) did a fantastic job, even completely blocking a couple constantly-blinking blue lights on my electronics. I only posted a reply because I feel this question wasn't concisely answered. However, this has been a very helpful post to me. I keep coming back to use the color spectrum chart comparisons and the reason I got the Uvex in the first place. Too bad neither pair I tried fit me.

Here is a colour spectrum test image:

will-plain-red-or-orange-lenses-block-blue-light-for-sleep?

If you are not colour blind and your monitor has a normal colour range, the two bars should appear identical for any effective blue light filter. In theory you also could print out the image to test ambient filtered light sources (like light fittings or sodium lamps).

Quality of filters will vary from something no better than cellophane, up to EN207 laser protection visors (i.e. Argon/Krypton lasers in the case of "blue blocking" glasses). Considering the disability-adjusted life years of inadequate sleep; don't buy glasses lacking a spectrum graph/histogram data sheet. Unless you prefer wearing placebo glasses.

Most blue-light filters will halve the amount of light reaching the eye; for this reason strong care should be taken if driving at night with tinted glasses in a jurisdiction where this is otherwise legal. The same photosensitive ganglion cells, whose blue-light origin in sea dwelling animals controls our circadian rhythm, also controls our pupil dilation - hence the impression of brightness while wearing filtered glasses. Pupil dilation might not offset the overall light reduction in low light conditions.

Filtered glasses and light sources have proven to be far superior to any software solution I've experienced (f.lux for example); possibly due to the inflexibility of the operating system colour-space or the impure light spectrum of liquid crystal display.

Incidentally, if your PaleoHacking also includes an experiment with biphasic sleep, filtered glasses can be useful to avoid melatonin disruption during the sleep interregnum.

You can buy clear glasses for indoors that block the short UV rays which can damage eyes. They are specially made and you can ask for them at an opticians. They are recommended for people with macular degeneration and other eye problems, as well.
