Well, Anons, I'm pretty fucking livid. Took a financial leap on some supposedly really good frames and lenses back in 2016, and they both broke down faster than anything I'd ever bought cheaply as a kid from Wal-Mart's optometry department. The soft rubbery coating on the nosepads and arms disintegrated first, which were replaced, and then the second set did the same thing. And now the very expensive ballistic-rated lenses have their coating failing, which will eventually spiderweb out from the annoying blur they currently are into a facade that will ruin the lenses completely. And the company I bought from have taken the 'your problem now' stance, in spite of having babied these things.
I'm allergic to metal and so have to have composite frames, but I don't know who the hell to trust with build quality or material composition. I live in Florida, so conditions are hot and humid even today, in late November, which may have contributed, but was unavoidable. What eyewear would you take if you had to bring a single pair into Vietnam for a couple years? What brands are good? Which are shit? Does anyone know what plastics are desirable and which are to be avoided? All of the above for lenses, too.
Image is what I bought, the RX-456. I actually really like how they look and fit, especially the wraparound; I can hang upside down and they won't budge. But I can't be buying new frames and lenses every couple of years.
Eyewear general, I guess. Nightvision/thermal/goggles discussions welcome, but try not to expand into mounted optics themselves.
