Works well, especially in rainy or cloudy weather. I use them all day but they are most effective in darker weather. Makes things very clear. The quality seems just as good to me as the ones I had on sale for $10 20 years ago. However, I think a better price would be $20 since it's old technology and plastic frames. I think you're paying for the name. I've tried cheaper fakes but they don't work as well as this one. Also, I have a pretty big head and they fit perfectly. They seem to be more durable than bin sunglasses.
