ABSTRACT:
FIELD OF INVENTION
This invention relates to automobile visors, specifically to a transparent glare visor that filters and dims a driver's view of headlights at night.
BACKGROUND OF INVENTION
Drivers at night face bright headlights from opposing traffic. Modern vehicles have brighter headlights in general and many are placed at a higher level. A large percentage of vehicles also have headlights that are either misdirected, out of alignment, or on high beam. Meanwhile the number of registered vehicles and volume of traffic is always increasing. As a consequence anyone who is sensitive to bright lights is often distracted when driving at night. Such a driver needs a means of self-defense and sense of control over these conditions. Current transparent rectangular visors are used in the daytime as sum visor extensions but are not perfectly suited for use at night to dim a driver's view of headlights. These rectangular visors darken a driver's whole view if lowered enough to completely filter headlights. Some rectangular visors are made of a lighter optical material but these do not sufficiently dim the driver's view of headlights. Prior art patents for the purpose of reducing headlight glare such as U.S. Pat No. 4,818,011 4/89 Cherian, 3,695,658 10/72 Vacha, 3,351,375 11/67 Wheeler and 2,833,591 5/58 Kurtzke, all have inherent limitations in their structure and use.
SUMMARY OF INVENTION
Accordingly, the object and advantage of the present invention is to provide a driver with a simple inexpensive automobile accessory that easily slides onto an automobile sun visor and is there ready for use whenever needed to filter and dim the view of bright glaring headlights at night. An accessory simple and easy to use that improves a driver's vision safety and comfort when driving at night. The present glare visor pleasantly filters and dims a driver's view of all headlights ahead without obstructing the driver's view of the road and traffic. Using the glare visor relieves eyestrain and discomfort for glare sensitive drivers. From the driver's position the unusual shape of the glare visor underside follows the relative path of vehicle headlights as they approach and pass. All the driver has to do is look under the bottom edge of the glare visor for a normal unfiltered view while receiving a filtered and dimmed view of objectionable headlights.
