In 20+ years as a police officer, I did many jobs, from Motorcycles to SWAT. With that, I have worn many types and brands of sunglasses, from Oakleys to gas station goggles. These are hands down the finest sunglasses I have ever worn. From recreational motorcycle riding to work, they go everywhere with me. Comfort level is beyond expectations and I get no sore spots behind the ears thanks to the Memory Nylon frames. Now, as a locomotive engineer, I am required to wear safety glasses all the time at work. Even with my Oakleys I have to take them off to read the control screens in the cab of the motors. Not the case with my STNGRs, the clarity and quality of the lenses make it easy for me to see the computer screens. I wish I had these the last 30 years!
