Abstract: Eyewear having forehead-ventilating provisions includes a laterally-elongated slat projecting at or slightly above eye level for the wearer. The eyewear provides a solid front extending between upper and lower margins as well as left and right ends. The slat is secured to either the upper margin or else the ends of the eyewear to project, as said, forward from the solid front at or slightly above eye level. The slat defines a trailing, laterally-elongated slot. The slat and slot are cooperatively formed to divert air that is incoming on relatively level paths for the solid front—or slat—onto angled paths aimed at streaming up and/or fanning out across the wearer's forehead. The slat and slot are scaled and proportioned to enhance forehead-ventilation and refreshing-comfort to wearers active in activities in which they are rushing themselves or being rushed forward at exhilarating but not fearsome rates of travel.

Abstract: A pair of sunglasses is provided with a polarized region in the upper portion of the eyeglass lens and a non-polarized region in the bottom portion of the eyeglass lens so as to permit reading of polarized instruments through the non-polarized region. The two regions may be separated horizontally at the halfway point or below the halfway point such that, by tilting one's head upwardly and looking through the non-polarized region, one can readily read the instruments which would appear black through the polarized region due to the cross-polarization. In one embodiment the polarization level is gradually decreased from the top to the bottom of the lens in a polarization gradient in which there is no polarization at the bottom portion of the lens.

Abstract: An improved method is provided for applying an antireflective high contrast coating to a lens, as well as a lens system made with said method. By coating the lenses with a mixture of an oxide and fluoride, the transmission of undesirable visible light wavelengths is reduced, as is the reflection of undesirable light. This combination not only increases perceived sharpness and detail associated with viewing objects through the lenses, but also reduces undesirable reflected glare. Utilization of increased vacuum during the coating process reduces problems of humidity associated with plastic lenses. The combination of oxide and fluoride is controlled to reduce colored tint or hue in the resulting lenses. By imparting little to no color hue to the lenses, the lenses virtually eliminate any undesired color shift associated with prior art lenses.
