Amazon should do a sampling of inventory and check whether they pass or not.

And it may happen to be that blocking the visual with the counterfeits also blocks the invisible wavelengths. Or it may not.

There should be some statistical evidence provided.

I did read from one of the recommended manufacturers that they tried to warn Amazon about this for months. They also tested them and they appeared safe in the tests they ran even though they were not legitimate.

But only Amazon knows what they have actually sold.
