Abstract
A driver vision field extender uses flexible vinyl Fresnel-type prism lens material with substantially parallel horizontal straight linearly extending prism lines. The parallel lines permit wide side by side views without substantial distortion. As the driver vision field extender is intended to be positioned contiguously along the windshield, the driver vision field extender after installation preferably exhibits a concave shape acting to focus the light defining and delineating overhead objects towards front-seated passengers such as the driver.
