- eyeglass lenses affixed in the frame, the eyeglass lenses having an upper shaded portion and a lower portion, the upper shaded portion having an upper edge positioned substantially lengthwise along an upper edge of the lenses and a lower edge extending horizontally across the lenses and terminating at a position above a pupil position of the lenses, wherein the upper shaded portion blocks light relative to the lower portion.
An article comprising an eyeglass frame holding eyeglass lenses, the lenses having a viewing window portion with a maximum length dimension of between 4.5 and 8 centimeters and a maximum width dimension between 0.5 and 2.5 centimeters, the viewing window portion defining an area above an uppermost edge of a wearer's pupil.
A method of operating a motor vehicle comprising the steps of:
- wearing eyeglasses having lenses with a light blocking portion positioned substantially above a field of view;
- selectively driving with a substantially vertical head orientation such that the light blocking portion remains substantially above the field of view;
- detecting an oncoming light source;
- selectively tilting the head forward while maintaining eye position to bring the light blocking portion substantially into the field of view;
- and
