As an avid mountain biker, I've long been thankful that I live in the suburbs. I don't think that I could handle weaving in and out of lines of yellow cabs and SUVs all day, everyday. All it would take is a single instance of obliviousness on the part of myself or a driver caught in the long line of traffic, and devastation could ensue.
Recognizing the need to provide cyclists with a bit of extra vision, designer Billy May has come up with the Nike Hindsight glasses. The glasses use Fresnel lenses, originally designed for lighthouses, on the sides to provide increased peripheral vision of up to 25% per side. The glasses would be invaluable to cyclists in pushing vision beyond the standard 180 degrees so that approaching vehicles and other hazards could be detected long before presenting imminent danger.
As far as the "Nike" goes, that's just wishful thinking on the part of the designer and Nike is not affiliated with the design, though it's not a stretch to see the gigantic sports manufacturer producing and marketing these glasses under their infamous "Just Do It" slogan. Regardless, the design certainly presents a simple way of addressing a very real and common problem.
