The FDA obviously cannot regulate the Sun. The Sun just exists and still would even if the FDA declared it illegal. But staring at the Sun is not recommended (ask your eye doctor) because of a condition called solar retinopathy that you can get from staring into the Sun for too long. Also, common sense says that staring at the Sun is not eye safe. Headlights? I wouldn't look directly into the filament of the bulb, as that can cause eye damage too. Staring at the reflector from extremely close range does cause eye discomfort, because enough of the emitted light is in the visible range that you notice it.
IR lasers are even more dangerous than visible lasers because the blink reflex is not triggered. It seems painless, perhaps until you hear a pop in the back of your eyeball from your retinas overheating. That's why IR lasers can only be class I but visible lasers can be class II.
http://www.lasersafetyfacts.com/reso...er-classes.pdf -- see "Techical Notes" box at the bottom. If your eyes are operating properly, you won't be able to stare into a class II visible laser for long enough for it to do damage, but IR lasers are different because you may not even know it's hitting your eye.
Veil is likely reducing the IR returns, which reduces PT distance. It's obviously not going to stop 100% of the returns (nothing's perfect) but as long as it reduces the return from the headlights below the peak you get without Veil, it seems logical that PT distance will be reduced. Where this obviously fails is if the car is returning more IR than the Veiled headlights or plate; in that case, the limiting factor will be the amount of IR returned by the car body itself.
I would suggest that @
Mirage test the amount of returned IR vs. number of coats of Veil
with a light meter tuned to the 905nm range (the same type that you'd typically find in a camera). Human eyes aren't very good at telling how much light is returned, and the responses of our retinas to visible light is likely nonlinear. Also, the sensors in the IR camera used to conduct the tests may also be nonlinear so it's not really possible to tell how much reduction you're getting just by looking at those videos. But since you were obviously involved with developing the product, don't you already have some data on this?
Agreed. I bought my can of G4 thinking that I was going to try to help protect only the license plate on my car, which is white. Of course, I got a nearly IPT on a BMW running no front plate at all from over 2000' away with a LiDAR gun. That car was white. I think it's safe to say that there are some cars for which Veil would be almost completely useless. That said, putting Veil on the plate, which is the strongest reflector, may help a little bit. It certainly cannot hurt. But I could not even do that because of how dark the G4 was.
