I do agree those tiny helmets don't look like much help. But not all helmets are like that.
I use a full helmet, shaped like the one you use when riding a motorcycle, just not as heavy.
It already saved my face from scratches in one fall I had.

I had a friend in college who worked in a university lab testing bike helmets; this was 20 years ago now. They're only gotten better since then.
But it's true, bicycling helmets don't do much for protecting your face. But that's not what they're designed for; they're designed to reduce or prevent brain injuries from knocking your skull on the road or a curb. A full-face motorcycle helmet would be even better, but there's a tradeoff there in weight and ventilation (and cost), things that are more important to bicyclists than motorcyclists. Even a lot of motorcycle helmets aren't full-face and don't protect the face at all. But the idea with safety equipment isn't to completely eliminate all possible injury, it's to reduce risk to a reasonable degree; for the injuries you're likely to experience as a cyclist, a good cycling helmet is designed to protect against those. But it's not going to help keep a branch from poking your eye out on a backwoods trail.
Finally, the charge against bike helmets from all these anti-helmet people lately isn't that they don't help prevent injuries (they absolutely do), it's that they allegedly cause more accidents by making car drivers more reckless around cyclists. The claim has nothing to do with physics, and everything to do with psychology. Personally, I think it's a terrible argument to make, and if there's any truth to it, it simply shows that we absolutely need to mandate that cyclists are provided with physically separate roads from cars. Considering how dirt-cheap cycling trails are to build compared to car-roads, how much better for the environment cycling is than driving in cars, and how much public health would be improved by more cycling (which would reduce healthcare expenditures greatly, and also improve workplace productivity and reduce sick time, all important factors for good capitalists), there's simply no excuse for governments to not be buildings lots and lots of safe cycling paths and encouraging cycling.
