Nike’s Hindsight glasses are designed to help athletes like joggers and cyclists extend their peripheral vision. The idea is to enable the wearer to see objects behind him without having to look backwards.

Fresnel lenses are used on the side of the eyewear to provide a greater field of view than 180⁰, the normal human limit. 25⁰ of field of view are added on both sides using the lenses.
