Same holds true with copper lenses on freestone streams. They pick up trout in that kind of cover better than do the rose glasses. But the reason the different colors make such a big difference is because Tri-Spectrums are the best angling sunglasses made, period. Unlike most sunglass lenses, Tri-Spectrum lenses are true de-centered lenses of prescription glass quality. Each lens is ground and polished from a solid block of minerals for consistency of quality and for far less distortion and greater peripheral vision than with other sunglass lenses.The lenses transmit more light at the three bands of primary colors so the contrast between each color is sharper and clearer for the utmost definition at the edges of object and improved ability to distinguish fish from objects underwater. And the lenses are set into the Italian-made frames to all but eliminate lenses popping out. Midway style tortoise frame now with new blue mirror coating to further reduce glare. Not available in Rx.
Advantages of Tri-Spectrum Sunglasses
Dave Perkins, Vice Chairman, The Orvis Company, on HVO Tri-Spectrum Sunglasses
“Our new HVO Tri-Spectrum polarized fishing sunglasses are the best sunglasses for fishing I’ve ever worn, and I’ve worn a lot. They’re the only sunglasses made exclusively for fishing, and are exclusive to Orvis. When I first wore them, I couldn’t believe how well they worked. They worked so well I compared them to all my other glasses, literally standing near the water and finding an object, hopefully a fish, and swapping out several glasses to see the difference compared to Tri-Spectrums. Every time, I was able to see more beneath the water’s surface, with more clarity and better contrast than with any glasses I’d ever tried.”
I am more than impressed with the visual clarity and fish 'spotting' capabilities the new Tri Spectrum sunglasses provide for me. I have worn Maui Jim, Revo, Smith, and some other so-called quality sunglass companies, but I have not seen the glasses perform as well as the mfg'ers stated.
I cannot overemphasize the importance of good eyewear. A quality pair of wraparound polarized glasses is critical for sight nymphing. A good pair with glass lenses isn’t cheap, but it’s well worth the investment. This purchase often merges the gap between success and failure. Encourage your fly-fishing companions to try the new Orvis HVO Tri Spectrum polarized sunglasses; I was one of Orvis’ field-testers for them, and they are truly amazing.
