They made friggin cars with friggin laser beams on their friggin heads!
So how close can you get your eyeballs to the sensor? Even if IR isn’t in the visible spectrum, that doesn’t mean it can’t damage your eyes at high power levels. If anything, its more dangerous because you won’t notice it.
Cameras have an IR blocking filter and it still damaged the sensor. I don’t know how they can consider it eye safe. I wouldn’t want to be close to one.
Most cameras do not have IR blocking. This is how you are able to see IR LEDS with your phone, including remote control LEDS and security cameras with night vision.
Also, infrared is very safe and you are spreading disinformation.
Every normal color camera has an IR filter. If they did not, the photos would be pink in sunlight. Some IR gets though the filter allowing you to see IR LEDs, but it’s significantly attenuated.
So will it burn out all the cameras in Teslas’ “self driving” systems, too?
😂 perhaps speed cameras too?
I’d guess those are too far away for the filters to be ineffective, unless they don’t have the proper filters on them, which is definitely possible considering how bad most of the tech they use is. Of course, same with Teslas. I bet they don’t have proper filtering on their cameras either. Lol

I always wanted a car with a built in laser blaster. It’s one firmware update away from accepting targeting commands
“Do not point a camera directly at the lidar,” one support page admonishes in no uncertain terms.
Do not taunt Happy Fun Ball
The company specifically called out “close-ups” as the problem, meaning that our phones should be safe with distant shots
Also I think they’re using lidar with a frequency of 1550 nanometer which can’t penetrate the eye or cause damage.
If you could find a source for that it would be comforting lmao.
And remember
To heat 1 cm³ of water by 1°C, you need approximately 4.184 joules of energy, as 1 calorie is defined as the energy required to raise the temperature of 1 gram of water by 1°C, and 1 cm³ of water has a mass of about 1 gram.
So to heat your eye of 1cm3 in 1 second you need 4.2 watts of infrared to enter your eye. That sounds too much power for lidar, but couldn’t find quickly how much power is emitted by lidar though…
Never realized Laser Safety was such a wild read. It just keeps getting better as you go:
A pop or click noise emanating from the eyeball may be the only indication that retinal damage has occurred, i.e. the retina was heated to over 100 °C (212 °F) resulting in localized explosive boiling
If you go to luminartech own website, on the home page, if you scroll abit down, they have a LiDAR 1550nm vs 905nm section and a downloadable 7 page pdf where you can read about it. It’s of course biased because they themselves are making it, so bear that in mind.
Good. I need one of those and make it wearable for the people wearing smart glasses.
