ABSTRACT:
A manually-tiltable anti-glare device is provided for attachment to eyeglass frames or sunglasses to save lives by blocking the rays of a rising or setting sun, from eyes of a wearer the anti-glare device, while performing outdoor activities, or driving a vehicle. The manually-tiltable device is easily adjusted by the hand of the wearer, between partially lowered and raised positions, to follow the rising or descending sun, while, at the same time, allowing the wearer to safely walk, bike, hike, or see a roadway while driving. The anti-glare device includes a stop portion which prevents the anti-glare device from being moved downwardly or lowered to a vertical position in front of the wearer's eyes, thereby enhancing a walker's, hiker's, cyclist's or a driver's vision, and avoiding any dangerous accidents or conditions. The anti-glare device includes very dark lens-type portions, which are small enough to be seen around comfortably and safely, but which are large enough and high enough so as not to impair the walker's, hiker's, cyclist's or driver's peripheral or straight ahead vision. The very dark lens-type portions are positioned, sized and dimensioned so that they cover and protect the eyes of the wearer, no matter what the distance between the eyes of the wearer.
