Back in the eighties, Honeywell had an electronic enhanced lens for satellites that detected a laser and protected the satellite’s sensors from it. I would think that something as simple as polarized film on a pilot’s canopy and additional polarization oh his goggles would do the trick.
The Chinese are foolish to start playing around with a potential weapon long before it would be used in combat. That gives more time to develop and deploy counter measures. One counter measure would be to fire a laser source seeking missile.
U.S. Military binoculars have laser shields built in.
I have no idea how effective they are.
