ImpactX® lenses are photochromic. This means they get dark from low to high light transmission within few seconds and reaching a custom color from an initial clear state. They enhance contrast, improve visual acuity and depth perception. ImpactX® lenses are 16% lighter than CR-39 and 10% lighter than polycarbonate; they have lower internal stress and chromatic dispersion than polycarbonate, resulting in sharper images, higher definition, reduces “rainbowing”, and more visual comfort.
After purchasing over 100 pair of another popular brand I am now on my third pair of Rudy project and the lens quality is superior
The RX insert fogs. The top rim of the sunglasses hits the helmet brim constantly pushing the glasses down off your nose.
I am a city/designated bike trail daily commuter in the Pacific Northwest so weather is a huge factor. I experience rain, fog, freezing temperatures, and sunshine. I start in pitch dark and return in light. I was highly impressed with the customer service rep who emailed me suggestions, links, best fit predictions and color choice that works best for city commuting (brown lens). I am a petite Asian American female so fit was a concern as well as needing a photochromic option. The Rydon Slim comes in so many options including many photochromic color choices. The ability to adjust nose pads as well as the frames is such a benefit. I could easily shape them to fit me well and stay on which has always been a previous issue for me. This week we hit 22 degree morning temperatures and even with a mask on to keep my face warm, I was really impressed how well these are ventilated to keep the glasses from fogging up. Wow! Unexpected and impressive as I thought for sure they would fog up. I have experienced rain and fog and these work so much better than any other glasses I have unfortunately wasted my money on before finding Rudy Project. The brown lens cuts down on glare from rain, lights and oncoming traffic in the pitch black mornings. And when I return home in the afternoons, I can count on the photochromic lens to provide UV protection for my eyes. I am biking about 1.5 hours total every day and these work exceptionally well. I am very impressed with the glasses, customer service and company.
After doing an aero optimized TT fitting, the easy winner for which helmet outperformed the rest across all positions tested was the Wing. Surprisingly light and incredible visibility are the *chefs kiss* icing on the cake for a winning package.
Vents well, changes color well. Doesn’t fit well. Slides off nose.
