.... is another alternative. They are pricey, but you get what you pay for. And if you take care of them, they could last for years, which might make them less expensive on the long haul than the less expensive glasses out there. ( The glasses I was replacing was a pair of seven year old $300 Nikons - bought for $40 at Sierra Trading Post - which finally started showing enough wear that it bothered me ).

I bought a pair of the Variant model a few months ago on sale. Follow the link. Read the SR-91 information while you are there.

So far, I am quite pleased with the glasses, with one exception. The frames are a bit hard on my ears, but that problem was solved by using a style of "Chums" which cushions the frame contact with the ears and keeps the glasses on under difficult conditions.

P.S. I researched the Smith, Costa Del Mar, and Haber lines before I chose Kaenon. A couple points to keep in mind - glass generally will give you clearer vision but will shatter on impact, poly will give you shatterproof lenses but will more readily scratch, some glass lenses, like Kaenon, have high quality optics and are also shatter resistant. Protecting your eyes with good optics and from accidental breakage are two important considerations - more important than how comfortable the glasses are and how well you can see fish with them. You can always replace less expensive glasses, but you can't replace eyes.
