I’ve had all major brands of sunglasses over the years, these are my second pair of Costa sunglasses. Best shades ever for boat, motorcycle, any outdoor activity

The sunrise silver mirror lenses are the absolute best lenses for low, med and cloudy light conditions. My fishing buddy asked me why I was wearing them in the early AM on a cloudy day. I took them off and he couldn't believe how much more detail he could see. I've put them on and seen crab pot floats 50 or 75 feet in front of my boat that I couldn't see without the glasses. These aren't cheap but if you're on the water or the road and you need contrast in low to med light get these glasses. Also, because they are polarized and mirrored they will also work in bright light conditions, just not as good as the bronze or blue lenses but they will work in a pinch.

I bought these to fish with. I’m a true believer that you must have top quality sunglasses to cut through the water glare. I almost always prefer the 560 glass lenses, but sometimes the extra weight has the glasses sliding down my nose , particularly in the heat. The ultralight weight of these new lenses was very noticeable when I tried them on for the first time. Great lightweight sunglasses

These glasses actually stay on your face when you are looking down. I have a problem with glasses always sliding down and falling off. These stay put and you cant even tell there on after a few seconds.
The clarity of the polarized lenses are exceptional and you get full sun blockage all the way around , the sides and the bottom.
Best Glasses Ever.
