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.
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.
A rider’s clear benefit is in the early warning of approaching vehicles, but a less obvious advantage is reducing the necessary head rotation to check completely behind oneself. Moreover, while the project was directed towards bicycling for the sake of simplicity, there’s a myriad of sports and activities where a greater field of view becomes an advantage, so feel free to speculate.
Remember: Concept means these are not real – yet – but I would totally wear these if they were. Even riding through the mean streets of Bay Ridge is a frightening proposition as grannies and the habitually stupid try to pass me all the time on my bike.
