Car's LiDar sensor might damage your camera.

Quite interesting, sounds crazy but might be true.

Can A Car's LiDAR Sensor Damage Your Phone Camera? Viral Video Sparks Debate

Smartphone cameras can indeed be damaged when they are pointed straight at the LiDAR sensor.

LiDar can damage the retina and the vitreous body of the eye with bright laser radiation.

Laser powers of less than 0.39 mW are safe. And even in the smallest "toy" LiDar, the power is already orders of magnitude greater.

Now they are inflating the myth that for safety in automotive LiDar, lasers with a wavelength of 1550 nm are used, which is supposedly safer for the eyes than lasers with a wavelength of 905 nm at the same power.

The reason? In the wavelength range of 400-1400 nm, the laser can pass through the vitreous body and focus on the retina. And 1550 nm only burns the vitreous body of the eye, and not the retina. However, the risk of eye damage is actually higher, since the eye does not react to infrared radiation with a length of 1550 nm, and does not blink, does not close reflexively.

To protect the eyes from lidars, it is necessary to use special protective glasses. But even here, not everything is simple, even special glasses block radiation only at a certain wavelength.
Everything is bad.

Imagine how safe is this lidar sensor for the human eyeballs.

Interesting, strange how this can be allowed if it’s that bad.
What about the LiDAR we have in our phones, are they less than the 0.39mW you specified?

Surely there must be a "max" watt just as there is a max SAR value for phones?

Not sure why this was moved, the whole idea was to "warn" people so that they don't destroy they iPhone (or iPad) camera.
