Abstract
A flexible transparent lens that may be darkened to substantially block passage of bright sunlight is releasably or fixedly secured to the underside of a bill of an article of headwear such as a cap. In a first embodiment, buckles are affixed to the upper opposite corners of the lens and complemental snaps are affixed to the opposite rear corners of the bill. The lens follows the contour of the trailing edge of the bill when the snaps and buckles are engaged to one another. The top edge of the lens is spaced forwardly of its bottom edge when the lens is in its bowed configuration so that the bottom edge is closely spaced to the face of the individual wearing the head gear to thereby minimize the amount of sunlight reflected into the individual's eyes from reflective clothing and other sources of reflected sunlight. In another embodiment, the lens is riveted or stapled into position. In all embodiments, the lens may be clear or darkened.
