I was considering buying these glasses for about a year. Although, less money then a lot of brands, it was expensive for me. I use these for cycling. I cannot be happier. I used tinted lens for days and clear for early AM. I had heard that the lens were difficult to change, but I feel it is very easy. A great product. Also...I have purchased several items from opticsplanet....Always fast shipping and easy transactions. KUDOS

Excellent lens quality (I´m a long time Serengeti user). Amber Modulator darkens & lightens more than Serengeti Drivers, so that makes them great for all light conditions. Anyway the color isn´t exactly the same as Drivers, you´ll need a few days of habituation for the slight difference. Good for sports too, due to lightweight; I run with them. Like any good lightweight sunglass always keep them in the case.

I've tried a variety of sunglasses for tennis and these are by far the best. If you decide to change the lenses, read the instructions carefully and be gentle.
