Bottom line: The optics are incredible, and they were so comfortable I usually forgot I was wearing them. If you can afford these, they are worth it- especially if you are going to be on the water where there is inescapable glare for long periods of time.I would normally never spend $200+ on a pair of sunglasses, but I was going to spend a week on a chartered sailboat and I knew I'd be on the water from sunup to sundown, so I went ahead and splurged.The first thing I noticed when I put them on at home was the amazing optics- they really are simply incredible. This was only re-enforced once I was on the water. One nice feature- the glasses have rubber on the tips of the side pieces (so- behind the ears) and on the bridge of the nose, so even when I was covered with sunscreen, these glasses never slipped.Negatives- Price. Second- these are just slightly tight just behind the ear. I tend to get headaches when I wear glasses that are snug or tight, so at first I hated this "snug fit" and thought I'd send them back, but I put them on to mow the lawn and in 30 seconds I forgot I was even wearing them. They were NOT tight on the temples, and I think that's why I had no problems with these.UPDATE- 1 year later- I still absolutely love these glasses, wear them all the time- definitely worth the $.
