Hi. I hope someone can help. I have bought a R.E.M. dreamer mask which has 2 led lights and an infrared detector which detects eye movement during REM. I’m a little concerned that the infrared detector could damage the eye in some way as I’m sleeping with this detector thing bouncing off my eye all night.
There is IR everywhere, sunlight contains lots, your TV remote uses it, the heat you feel from an open fire is IR. We can't see it because we don't have any receptors. Unless it's some kind of laser I can't see how it can cause damage.

There are some of us who find it difficult to go to sleep at the best of times.How about a sensitive strain gauge or piezo vibration sensor taped to the subject's temples near the eyes?
I think arc eye is caused by UV, same as sunburn which I've had many times when welding without gloves.

Well, maybe, just maybe, the person doing this experiment isn't thusly afflicted. Besides, going to bed with one piece of tape on you forehead is hardly "instrumented up like a cyborg."All instrumented up like a cyborg? No chance.
