I have a 480W red/nir light that's super bright, the blockers don't even work well.

I got these glasses, they're great: https://www.amazon.com/gp/product/B00C61VWP8

Cuts out all the red and nir light entirely with no bleed through around the edges.

The ultra-budget option is tinted safety glasses from a welding supply shop, $8 or so, and available in shades 3 (dark normal sunglasses),4 (typical ski goggles) 5 (the darkest shade glacier goggles are offered in). ANSI/NIOSH certified. Intended to protect from UV/Visible spectrum/IR emmited from grinding, brazing, etc, but work equally well for sun reflected off snow at altitude.

Color accuracy is shit, so you don’t want to drive with them on, and not ideal if you need to differentiate colored pro.

I typically go for the “nemesis” branded ones, since they look like normal wraparounds. I’ve literally dropped a loaded expedition pack on them and they survived.

Will be a little cheaper if you have a local airgas or similar welding supply place.
