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.
Zenni sells one now, with privacy as a selling point
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.
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.
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.
