I have a pair of turbine with non polorized sapphire iridium lenses. Really don't like driving with them as they seem really dark to look through. Even darker then my other ruby red and black Iridium both polorized sunglasses I have. So I'm gonna replace my lenses with either prism deep water polorized or the regular sapphire iridium polorized lenses. I looked through my buddies twoface shades with the polorized sapphire iridium and I really liked them. Everything was way brighter then my non polorized sapphire iridium.........don't really no why as the light transmission has the same specs, so maybe things are just brighter because of being polorized. Anyone know which is better for driving? Deep water prism or sapphire iridium both polorized. Thx
