Bisphaera Speed Sunglasses - Matte Trans Stonewash/Clear to Black Iridium Photochromic

The lens looks clear in these photos because it is. This is a photochromic lens, untinted until UV hits it, then it darkens to a black iridium mirror and clears again indoors. The last image shows the activated state, so you can see both ends of the range before you order.

The Bisphaera Speed is a half-rim wrap: the rim runs along the brow only and the lower edge of each lens is left open, with temples tapering back to a thin blade. Matte Trans Stonewash is a translucent washed blue, streaked lighter and darker through the front so the temples read almost icy where the light gets through, with grey grip inserts along the inside of each temple and a silver Oakley wordmark across the bridge.

One lens covers everything from overcast to full sun, which is what you want on a long ride or run where the light keeps changing. These are not polarised.
