great glasses! great quality for the price and everything is so much clearer. great protection for my eyes and comfortable. I can wear these all day without having pressure sensation right behind/above my ears with some sun glasses. They are very stylish too. I use them for every day use or for fishing! i can see fish clearly in the water. would order it again!

My favorite sunglasses. It’s hard for me to find glasses that fit and don’t rest on my cheeks but these are great. And comfortable to be in all day. My only complaint is the coating on the lenses is not very robust. After about a year of wear the coat is starting to flake off the lenses but at the price point I guess I should expect corners to be cut.

These polarized sunglasses are a revelation! They cut through glare effortlessly, the clarity and protection is top notch. From beach days to driving in bright conditions, they deliver on every front. Stylish, durable, and with lenses that truly make a difference—these are hands down the only sunglasses you need. These are the second pair I have bought thanks to my kids who like use these for their play "private investigator" game :)

I bought these to replace my shaderays. I had to send those back every other month and got tired of them. I saw these and said…why not. After owning for 4 months, I have beaten these with sun, sweat, and dirt. They are still scratch free and hold up great in the Florida sun! I will buy another once I wear these out but if they stay like this, maybe not for a long while before I replace! Love them!
