I bought a pair of Cocoons fit over Rx sunglasses about 3 years ago and have pretty much used them every day since then. They work great for fishing in just about any light and I can't fish without them anymore. Alas, though, they began to fall apart at the temples due to some unknown reason. So, I contacted them through their website and asked if they could supply me with some new temples. I got a response about 1 1/2 days later and said that instead of new temples that they would send me a new pair under their lifetime warrenty program. WOW, I had forgotten all about the warrenty and was pleasantly pleased to receive a new pair. A great American company! The new pair is just as nice as the old ones and fit just as nicely. If you wear glasses, give 'em a try. They're great.
