Take a look at a pic of an alpinist atop a sick line in the mountains, and chances are they are wearing Julbo eyewear. When poor glasses may mean seared retinas and snow blindness that jeopardizes your life, Julbo is what you pick.
This pair of Zebra lights I bought complement two pair of Smiths (casual and sport), two Oakleys (casual) and another pair of Julbos (for mountaineering). I had been wearing Oakleys for as long as Oakley has existed, but started to feel they were putting fashion above function.
These Julbos replaced a pair of excellent Asssos specs I sadly lost on a ride. Their optics are second to none. Combined with their light weight and comfortable frame, I forget I have them on. The ear stems are straight, so bear that in mind when considering helmet compatibility.
The lenses are indeed light. I read a professional review that said they were dark enough to wear in SoCal, so I was surprised to see the lens appear completely transparent when I pulled them from the dark box. As a former AZ resident I am a bit skeptical about the Zebra light lenses ability to darken enough for truly brutal equator sunlight, they are really excellent for New England, where trees often shade the roads substantially. On fully sunny routes, these have been more than dark enough to keep my sensitive eyes comfortable, while still maintaining a vivid field of view. And they transition to nearly clear when the sky gets dark if I am out after dusk. (I expect this will work great for mountain biking, for that reason.)
These also provide some welcome venting for the eyes, helping to mitigate sweat, which is very welcome.
