You read the title. These things are amazing. Frank (I'm presuming he is the owner) is one of the coolest guys. He helped me find the perfect lens for my application (McKinley lens, which BTW is amazing, goes from Cat2 to Cat4), and made amazing prescriptions for my awful eyes (Almost -7.00).
If you are struggling to find some high prescription glacier glasses or an high prescription sunglasses that wont be 2 inches thick like I was, go for their Altice Venture model. I simply cannot praise this companies work enough.
