I will try to anser youi're questions. High contrast Yellow is hard on the eyes for extended use. so we developed the Mandrose to combat that issue. It is a soothing color contrast and really makes everything stand out. They perform great and can be worn for really extended periods with ease. They truly are an awesome low light lens.
The gray base performs as well and our lenses are what we call "Optically Perfect" meaning no matter where you look out of the lens there is no distortion. We have several different models available now and have some new models in production that will be unveiled at I Cast in July.
Our lenses are Policarbonite lenses and therefore some think that they are not as clear as Ground Glass. But you pay for GLASS and glass shatters. Our goal is to provide protection to you're eyes and a product that won't break. I know Guys and Gals are tired of paying $200-$300 for a pair of glasses that the frames break on so we provide a solution to that. We stand behind our product and look forward to serving our customers for life.
We are in the process of working side by side with Jordan Outdoor int. (Realtree camo and Outdoors) and are the first high end Sunglass company to do that. If anyone has any questions please feel free to email me and I will do my very best to help you out. Thanks
