Reader Billy May sent us these concept sketches for the Nike Hindsight, specially design biking glasses with specifically tuned Fresnel lenses for keeping an eye on approaching taxis/cars/baby strollers.Writes Billy:Nike Hindsight is, put simply, like giving bicyclists a pair of bifocals for their peripheral vision. By using Fresnel lenses on the sides of eye wear, riders can detect motion in a field of view beyond the normal human limit of 180º. To get technical, high power, diverging Fresnel zones aligned vertically distort into view an extra 25º of view on either side. In doing this, vision is radically distorted in the periphery, but as the eye detects only motion in that area, little clarity is lost in the process
