Just received my prescription sunglasses from SportRX this week. I have to say, the quality is top notch! Fit and comfort is superb. It took just over 4 weeks from ordering until I received them. Price, with a $90 off code, came in within reason, in my opinion, considering the details, High Index, Transitions, Progressive, Scratch coating, Anti Fog, Mirrored. I had to go with a model that was not my first choice due to my MASSIVE level of correction needed, and went progressive. Today will be my first opportunity to ride with them, dang sunset is too early already! This pair will replace my old Performance Bike house brand with prescription insert that I got before needing the bifocal. Well over 10 years on the insert, but is the second frame. I'll let ya know how this pair performs as far as wind protection after the ride.
