I had photochromics for several years. I found them mildly-helpful-and-mostly-unobjectionable in the summer, but ridiculously annoying in the winter (when they both tend to be darker because of low-altitude sun, and the temperature makes them clear up slower once you move inside).

Also, I was relentlessly mocked by the fashion police. :P

Ultimately I moved away from them.

Colors were not as bright, and the world seemed less alive.

Colorblind glasses such as EnChroma provide the same "hang out in really bright sunlight without needing to squint or shade my eyes" benefits, but make colors more vivid, not less.

I eventually transitioned away from regular wearing of sunglasses when I learned to soften the muscles around my eyes enough not to need them as much, but for a while my EnChromas were really great.

Be careful. Photochromics gave me (well, helped a lot in giving me) a horrible case of SAD. And when I mean horrible, it was way worse than moderate depression. 15 years later and I still have a habit of installing ridiculously powerful lightning everywhere just to make sure it never happens again. 

I go with magnetic clip-ons these days. I accept that I'll break/scratch/lose some, and just keep one in my back pocket and in my car.
