LEDs don't really output infrared though?

There’s definitely IR/far red diodes

Sure, but most fixtures do not output "significant infrared heat energy", at least not to a point where you'd need special "organic lens" eyewear. I never wear protection at work unless I'm working with CSP LEDs, regular stuff doesn't damage your eyes.

I got a pair of these Method Seven Agent 939 FX Full Spectrum LED Grow Glasses at the grow store for $85 yesterday. They do seem to work better than a pair of Oakley's, feels like my eyes can relax more. I think they give everything a slightly green tint if anything. Also I think the frames on this model are sturdier than their old ones that were known for breaking. I had a pair of HPS and a pair of Blurple LED, can't remember which one broke.

Anyway these 939's are nice, I recommend them. The sales pitch says they're the first organic lens to protect against the significant infrared heat energy of full spectrum LED lighting.

What is a significant amount?
I’ve got 2X30W IR fixtures in my 6.5X4.5Ft tent

I got a free pair with my HLG light. I say they are nice glasses and my eyes ‘might’ feel less strained but not worth the price tag if you bought anything other than the $60 pair.
I still use my tinted and clear safety glasses. All you need really.
Doesn’t matter what brand you wear you still need a ballcap to help from above

The bit about IR protection and leds is a sales gimmick: if you really needed it glasses with leds then why not in normal direct sunlight? It's much stronger both in visual range and IR.

Manufacturers adding "IR": it's never really IR, always far red which is not hard on the eyes in anyway, it's the weakest of all visible light. Real IR is not even visible.

exactly... id go even further, i dont think ive seen a grow light that puts out significant amounts of uv to do damage to your eyes, most of them are no where near the amount contained in normal sunlight.

i used to work in an industry that used infra red heaters to dry coatings, these were 3000w, 5000w, 10000w arays, they would heat up a stone cold pie to piping hot in a few minutes, no one wore eye protection it wasnt even suggested. i dont know of any old workmate that has had issues with their eyes... apart from old age....

i will wait till mid day here and do a few tests with my handheld spectrometer, i have a set of method sevens, some oakleys and i think i have some cheap tinted work glasses somewhwere, that will show what is doing the best job of filtering what...
