Nike Hindsight Gives You Unparalleled Vision

Nike Hindsight: "The urban jungle isn’t exactly the safest place for bicyclists. You need the right tools to keep you one step ahead of irresponsible motorists. The Nike Hindsight gives you superhuman like powers with extended peripheral vision so all those sneaky cars, beware.

They work similar to bifocals except for your peripheral vision. By using fresnel lenses on both sides of the glasses, riders can detect motion in a field of view beyond the normal human limit of 180 degrees. If you want to get technical about it; high power, diverging fresnel zones aligned vertically distort into view an extra 25 percent on both sides. Vision is radically distorted in the periphery, but as the eye detects only motion in that area, little clarity is lost in the process."
