I've had these glasses for more than 15 years -- so long that the prescription is no longer quite up to snuff: going to the eye doctor soon to get it renewed, so i can update the insert on these glasses, and use them another 15 years.
I've used them biking, mountain biking, sailing, kayaking, paragliding, mountaineering, skiing... and just for everyday use. They are comfortable to my face (medium sized male noggin), stay put on my nose, with the possibility to squeeze the nose piece to fine-tune the fit.
I have progressive lenses in the insert, that worked very well for close-up as well as distance viewing.
I _really_ like the flip-up feature: as noted by others, critical when biking for instance, and entering a dark tunnel. I can flip up the outside tinted lens, and my eyes are still protected from the wind and insects etc. by the insert, i can still read maps, gps, etc. On looooong randonneur bike rides, i only need to take one pair of glasses, or i don't need to mess up with changing lenses in the evening and in the morning. When kayaking, I can flip up the tinted lens and get a clean view of my phone or gps.
After 15 years, i can feel that the ratcheting action is a bit less crisp than when new, but it still locks fine in the up or down position.
The lenses seem pretty durable: i've never babied them, i've lost them twice in the water, only for them to be found washed up on the sandy beach a day later, and i don't notice any scratches.
72 year old cyclist. Been across the US twice and North to South 6 times on a bicycle. I found the Exception to be durable and dependable . They came in handy when I had to flip up the shades to read the map. And the option to easily change lenses on those cloudy days was great. I believe I been wearing Exceptions for nearly 25 years. I'm on my 4th set. If you take care of them they last. Stay Safe and Stay Upright, Bill
I have a very high prescription and tiny face so most frames don't fit and wrap-around sport sunglasses are no good because of the distortion. These are the answer. I wear them mostly for tennis and have the Rydon with optical dock for cycling and running. I am so afraid of the exception being discontinued that I just ordered a third spare set of lenses and a third nose piece just in case I need them. They are beautifully made and I love the giant case that fits multiple pairs of glasses and spare lenses. Finally I can serve into the sun! I would give them 100 stars if it was an option.
