This is one thing I have in common with Jack Nicholson ... a love for the way the Ray-Ban Wayfarer's look and fit. I first found an old used pair of Wayfarers at a garage sale for 25 cents back in the late 70's. They fit so well and the price was right. I loved them. Later I learned that John F. Kennedy, Bob Dylan (on his first tour in England), and Jack Nicholson wore this model.
I lost them in the 90's and couldn't find a current model that were quite the same. It seemed all the models at that time were bigger and rounder, so I didn't replace them. Then the "New Wayfarer" model came out and although they call it new, it reminds me of the old pair I had ... size, look, fit. So I bought a pair and am love'n them again. I use them for sailing, driving, hiking, rafting, travel, etc.
These sunglasses actually block the wind better than some biking sunglasses I bought. I also prefer the non-polarized green lens to the polarized lens that came in those same biking sunglasses. When I ride into the shadows, the polarized lens blocked out too much light and it was hard to see the pavement. The green lens let's in more light allowing me to see better in shadows, yet without being too bright in sunny spots.
The 55mm New Wayfarer in classic tortoise (color 902) with the green lens is my cup of tea, although Dylan wore the black color. They stay on so well I don't need a strap to keep them on during vigorous movement. And your eyelashes don't hit the lenses when you blink.
Great gear!
