I am not a physics guy I'm just a husband trying to read in bed at night without disturbing my wife. Does infrared light reading glasses exist?Scientificly, can they be made?
Modern head lamps for mountainering etc. have a red light setting for this purpose. It's not infrared of course but its designed to minimize disturbing others who are still sleeping.Noasark said:Summary: I am not a physics guy I'm just a husband trying to read in bed at night without disturbing my wife.

Is "Spacetime Physics" available as an audio book?sophiecentaur said:Get started on Audio Books?

The letters on the page would reflect differently if you woreZapperZ said:Do you think the printed letters on the pages of your book emit heat differently than the rest of the page?
and used an IR lamp for illumination. IR Leds are used in trail cameras (readily available) and IR sensitive goggles are not too pricy (Amazon / eBay). You might look a bit bizarre sitting there in bed wearing all the kit but (hopefully) your wife would not be awake to see you.russ_watters said:-Night vision goggles.

in my post, which you quoted,ZapperZ said:Reflect WHAT?
A straight negative answer is seldom very helpful because it goes nowhere for an uninformed questioner. I gave him a solution (a real solution, in fact) to his problemsophiecentaur said:and used an IR lamp for illumination.

Any decent security camera today has NIR night vision, with it's own lighting. That's what the ring of LEDs is for:ZapperZ said:Reflect WHAT? presumably this person plans to read in the dark, which brought about the question in the first place.
The main upside of night vision goggles is everything would be in one package.Baluncore said:Night vision goggles are not needed. Most digital cameras are sensitive to IR.
Which is why I suggested goggles. They do not need to let any visible light out - plus they are fixed to your head so they do not need a hand or other support.Baluncore said:Take care that the light from the phone screen does not reflect off your face, to illuminate the book.
Somewhere I have a pic of me up to my neck in a pool in Cuba, drinking a Ron Collins, smoking a cigar and reading my half-submerged Kobo H2O. It is hard to imagine how even heaven could top that.sophiecentaur said:I'd agree with nearly all of that (my Kindle is not waterproof but I never found that a disadvantage)
Definitely a major downside to ebooks. As someone who likes to read books with maps and diagrams, this is a major drawback.sophiecentaur said:but eBooks really don't deal well with diagrams and half tones and many technical books are not available in the format. Horses for courses, I say.
Hah! What a beastly show off. (Lucky devil)DaveC426913 said:Somewhere I have a pic of me up to my neck in a pool in Cuba, drinking a Ron Collins, smoking a cigar and reading my half-submerged Kobo H2O. It is hard to imagine how even heaven could top that.
They are rubbish in that way. I remember having a rant on a Pro-Kindle forum about that and also the poor filing system (plus a couple of other things) and I was jumped on very smartly. "Don't try to tell us what we need" blah blah. It seems that the eInk system (great though it is) is the only issue that the eBook afficionados are prepared to discuss. They should be looking over their shoulders at the way the cheapest Smart Phones behave and smarten up their software.DaveC426913 said:Definitely a major downside to ebooks.

No, infrared led light does not emit harmful radiation and is not strong enough to cause damage to the eyes.
Infrared led light can provide a more focused and concentrated light source, making it easier to read in low light conditions. It can also reduce eye strain and fatigue.
Yes, you can use an infrared led light with any book that has reflective pages. However, it may not be effective for reading books with glossy or dark pages.
It depends on personal preference and the type of book being read. Infrared led lights provide a more focused light source, but regular reading lights may be more versatile in terms of adjusting the brightness and direction of the light.
Infrared led lights are most effective in low light environments, but they can also be used in well-lit areas for a more concentrated light source. However, they may not be as effective in bright sunlight or outdoors.
