I have been a big fan of Serengeti sunglasses for awhile. These are very nice for pretty much any activity, whether you're playing sports or exercising or just lounging around. They're very comfortable. I play competitive volleyball and I have found that the Sedona lense is the best lense for any type of light conditions. Sometimes I practice or play all day, but I can see just as well in these lenses at dusk as in the bright morning sun. They adapt to all kinds of light and you never even notice! I would recommend trying them if you have a similar situation where you need vision protection that can adapt to changing conditions.

I also have a very active lifestyle, and these sunglasses are the only ones I wear anymore. They stay on through anything, are very comfy and light weight, and have by far the best lenses available, especially for active/sporty people.

They are ok

Without a doubt, Serengetti Sunglasses are the best optics on the planet. Vision is better in any light, even while driving at night to reduce glare. Only problem I have is that the tip of the temples will rub the coating off the lenses in one spot when folded. Eventually this causes an area that is a different "color" from the rest of the lens, and is a distraction. None the less, Serengettis are the ONLY sunglasses I will wear.

1st pair purchased for $150 and lasted 5 years until lost in the Pacific Ocean. 2nd pair were also lost. I am on my third pair and probably won't buy a different brand unless these get discontinued. Motorcycling, snow skiing, beach volleyball, etc. These don't fall off...
