Fotonyk. The main new feature being a 'Lens Bumper' system, which provides protection to the face during falls or impacts, as well as a customizable look. The bumpers are available in multiple different colors. They can also be removed to create a half-rim lens. In addition to this new technology, air channels are at the top of the lens so users can easily manage internal airflow and mitigate fog. The fully adjustable ErgonoseX nose piece and variety of interchangeable lenses, including the unbreakable and photochromic ImpactX lens, make the Fotonyk a very individualized pair of glasses specific to each person and their own face shape. The Fotonyk is also available with high-tech prescriptions.
After putting them on, I decided I wasn't a fan of how the bumpers looked on my face. It's a toss up between scientist and going out to the shooting range kind of look. I did notice that they do look good on some people. I think probably the shape and size of my face have something to do with it. But this was no problem since the bumpers are removable. I understand the purpose of the bumpers especially for cyclists as it adds protection to their face if they were to fall or have a crash but luckily for me, I have yet to smash my face running (knock on wood) so I don't feel like taking them off is a problem. Removing them was not all difficult even though you have to remove the lenses from the frames completely to take the bumpers off. The lenses are super easy to snap in and out of the frames and once the frames are off the bumpers come right off. I assembled and disassembled them a bunch of times for testing purposes and it would take less than a minute every time.
Part of the purpose of the glasses coming apart is to remove the bumpers if you don't wish to wear them but also so that you can switch out for different color bumpers or you can even switch out lenses. There's a variety of options on the Rudy project website.
As far as performance these glasses did awesome for me. Obviously since it's winter most of my runs were in cold weather which is prime time for foggy glasses. As mentioned above, the fotonyks have air channels at the top of the lenses, I felt these helped tremendously as I didn't have any problems with the glasses fogging up. I even wore them once inside on the treadmill to get a feel for how they would do in warmer temps since I didn't think I would have that opportunity outside, as it turns out yesterday was about 65 and I ran 18 miles and no fogging problems inside or outside in the warmer temps.
Which leads me into my favorite feature of these glasses the transitioning lenses. I never really considered how having lenses that transition from clear to sunglasses would be so beneficial for running but now that I've been using the fotonyks, they really can be. Countless times I start runs when it's light and finish when it's dark or start when it's dark and finish when it's light especially in winter time. Usually I wear my sunglasses or have them on my head and usually have to move them from one spot to the other depending on if it's dark or light out.
fotonyks I figured I would just wear them and I was very happy I did. I didn't even notice when the glasses transitioned to the darker lenses. They transition so gradually so there's never a time when they seem too dark for when it's not super light out and they definitely are just as good as any other sunglasses when it's super bright out.
Lastly, the frames are super light which I love and they seem very durable. Luckily I haven't had to truly test their strength but they feel sturdy and they are specially made to withstand bike crashes so they should be able to withstand my abuses of them.
