More dangerous are infrared lasers.

Is there an effective anti-IR coating for eyeglasses like there is for UV? Seems like a good thing to have but a web search doesn't turn up much. It might interfere with facial recognition, but maybe that's a feature.

		Off topic: but in regards to UV protection, poly-carbonate(common in lenses) is UV-opaque. Completely clear uncoated PC lenses block most UV light. https://www.apollooptical.com/material-transmission-data-gra... Note the sharp drop-off in transmission for wavelengths shorter than 400 nm.

		Any laser light strong enough to damage your vision, might also pass through a optical coating. Distance can attenuate the strength, but really the only defense is proper rated glasses for the spectrum.

		Smartphone cameras typically have IR filters, but no idea what the attenuation is and if the same coating would be sufficient.

		Thin films of gold are reflective in the infrared and transparent in blue/green optical wavelengths. Gold can be applied to most surfaces by various physical vapor deposition processes in a vacuum.

What about visible lasers that lack an IR filter and have more IR energy in the beam?

		They will at least trigger the blink reflex
