None of which are practical if you need to wear glasses.

In many cases, especially for the higher end models, you can spend in the neighborhood of $100 to get an Rx face-shield. On the note of matters that didn't seem to come up much in the article, but that I feel like people should know:

The kind of cartridge you need to withstand teargas is not an N95, as the top comment points out it's quite a bit more involved. The downside of that other than cost and duration of the filter is that you'll feel a lot more resistance on inhaling than you're used to. For some people the combination of something on their face and the feeling of restricted breathing is unbearable, and mid-tear gas attack is a terrible time to realize that.

Consider also that this becomes far more important if you're working hard, say running around or fighting. Anyone who has it in their head to give this a try should keep those factors in mind, as well as get a kit to properly fit-test because again... mid-attack is a terrible time to realize that your fit isn't up to snuff. Likewise with training to don and doff.

In a lot of ways the article feels like clickbait that's extremely self-aware, but not really concerned with the practical reality of what they're implying.

There is a glasses kit available for the listed 3M 6800.

Just how big are your glasses? These aren't goggles that try to seal around your eye sockets, they are shields that seal around your face, sitting in front of your face by an inch or two. If you're worried about the glasses temple breaking the seal, it's still going to provide the vast majority of benefit.

Yes, in addition to inserts which are custom to the mask, there are small frames with a thin rubber band to keep them on you. They were great for roughhousing occasions as well as under mask. The key part is the thinness and impermeability of the band allows for a good seal.

As someone with big bulky eye glass lenses and frames I looked up the solution for the CM-6 derived masks, https://www.rigad.com/avec-spectacle-insert-for-cm-6-masks. Sounds like you'd have to get new lenses just for it and put 'em in, and the field of view is not great, but it is feasible.
