And what if you are hit in the eyes with the outout of 20 of them at once?

Like on a busy highway.

What if you are hit all day long, for hours, every single day?

History is replete with studies which were used to presume different exposures would be fine.




You’re right that it needs further studying, to not end as asbestos.

On a side note, you eyes are hit with more powerful and full-spectrum radiation (from IR to UV) from a burning star every day for hours (or at least they are designed to).


Agreed, during the day.

Eyes fully dilated during night driving don't constrict from flashes of coherent IR radiation, though.

BTW: this is neat: https://en.wikipedia.org/wiki/Melanopsin

The math makes this quite implausible for a random scenario. Perhaps a toll collector could introduce the right systematics to make the scenario not ridiculous on it's face.

Imagine pointing a laser at something more than five feet distant the size of an eyeball and then getting another laser to point at the same spot at the same time. And then another five. And those lasers are all attached to cars moving and the eyeball is moving too...


Put an IR filter in the car window glass?


You sound like the kind of internet commenter who whinges about how dangerous bicycles are on the road because someone in a car might swerve to avoid them and head-on collide with a tractor trailer.
