I guess? I space 10 years between photoreactive lenses, and although I've only done it twice, I didn't see any improvement between in the intervening years.

I haven't tried the most modern version, but they've never darkened enough, and they don't lighten quickly enough. On top of that, the shelf life of the photoreactivity is crap, and the performance degrades quickly, forcing me to replace my lenses more frequently than I otherwise would. IME, photoreactive lenses are just a contract to buy new glasses in few years.
