I have a question about eye safety, maybe someone here can advise me on.

Apropos of the protests going on, I've seen a lot of helpful pointers about preparing for getting tear gassed or pepper sprayed, such as not to wear contacts and to have tight-fitting chemists' goggles. But not wearing vision correction is not an option for those who need it, and the alternative to contacts is glasses, which are apparently incompatible with most eye protection from gas or particulates.

I am aware of the existence of some models of full-face gas mask that have internal mounting hardware for glasses, but in addition to being expensive themselves, they require getting lenses made and fitted to the gas mask (i.e. not compatible with regular glasses). I'm surmising the existence of these means that other, cheaper, spectacle-compatible eye protection doesn't really exist, but I thought I'd ask.

My personal interest in the topic is less about protecting myself from chemical ordnance at protests – I only wish I could attend protests (though if things got spicy in the right location I suppose I could collect my fair share of tear gas at home) – than from wildfire smoke. The conjunction of the No Kings protests and the local air quality alerts from fires in Canada reminded me I should really be doing some preparation in this space.

I'm allergic to smoke. (It turns out it wasn't con crud I kept getting at Pennsic.) My reactivity to smoke only seems to be gradually getting worse over time. So when I've heard reports or seen pictures from the left coast of the sorts of wildfire smog they have there, I'm like "...not enough steroids in the world." I mostly manage this threat by not crossing the Mississippi, but it could happen here. Or upwind of here. It has. If not quite so "blot out the sun" bad, certainly bad enough for me to feel it.

So I've been looking at half-face elastomeric respirators, but that leave eyes unprotected.

Any suggestions?

Edit: I'm getting a lot of suggestions that aren't really helpful because:

1) Most safety goggles are for protection against impact or splashes, and as such literally have vent holes that make them useless against gases and airborne particulates.

2) Involve buying a prescription eyepiece. The whole point of my question was looking for alternatives to buying additional prescription lenses. Like I said, I am already aware of options that entail ordering custom lenses, I am looking for alternatives that don't involve that and are compatible with regular glasses the wearer already has.

There may not be any*, which would be good to know, but that is the question.

Allow me to put a finer point on this. If there is no affordable, readily available option for eye protection against gas/powder attacks for people who are dependent on vision correction, then that implies something important about protest safety that is entirely missing from all of the discourse of the sort that recommends having a gas mask to go to a protest.

* Since posting, I learned the term PAPR, and am now wondering why they're so expensive and whether that's a technology ripe for DIY.
