Not thrilled with these replacement lenses. The polarization is limited to a narrow strip down the center of the lenses- the top and bottom of the lenses have a broad margin non-polarization, it’s horribly noticeable and is a distraction while driving. Additionally, looking at my cell phone while wearing the lenses is extremely distorted. I’m replacing 580g glass costa lenses. My cheap $40 back up sunglasses from academy sports display none of these issues. My previous costa lenses were scratched or else I would request them to be put back in. New tajima lenses are terrible in lower light conditions on the water in comparison to the costa blue lenses they replaced. Thought these based on a their troutbitten sponsorship(commercial) and would not recommend to anyone.
