I was in search of a light weight polarized sunglass for general use, and fishing. These have been spot on. My face is narrow, so wide glasses just don't fit. These fit perfectly. The optics are clear, and as good as a pair of old and somewhat scratched Maui Jim's. The rubber grip on the nose and ear pieces prevent slip when you sweat. The grey lens is good in most light conditions, but maybe not the best when looking right into very bright sun. My maui's are polarized HCl bronze, and if they get much worse, I will consider replacing with another pair of Costa's. The maui's are glass lenses, and although very durable, the weight makes them slip off your nose if you sweat.
I purchased these sunglasses for my husband. They are his second pair, and these are just as great as the first. For the price, this is a great pair of all-purpose sunglasses with polarized lenses. I also like (and so does my husband) that they are a classic frame style and will last him for years ... not too trendy.
These Costas r they best. Well made and the best vision ever. Everything looks HD w them on. Fast shipping and great price. Very pleased w my service and what they sell.
