This is a continuation-in-part of application Ser. No. 08/584,528, filed Jan. 11, 1996, now abandoned. 
    
    
     BACKGROUND 
     1. Field of Invention 
     This invention relates to bicycle helmets, specifically to a transparent sun shield for a bicycle helmet. 
     2. Description of Prior Art 
     Presently, bicycle helmets do not have sun shields. Currently, some bicycle helmets are made with visors. An example is the visored bicycle helmet in U.S. Pat. No. 5,333,328 to Roberts (1994). Visored bicycle helmets give a bicyclist eye protection against harmful ultraviolet rays. But, visors also block the upper peripheral view of the bicyclist, since visors are not transparent. 
     OBJECTS AND ADVANTAGES 
     The sun shield helmet assembly with eye shade portion made of material suitable to block out harmful ultraviolet radiation would protect the eyes from harmful exposure to the sun. In addition the interchangeable sun shields provide an added advantage, the wearer could change sun shields. If the bicyclist wanted to wear a blue sun shield on the helmet today and a green sun shield tomorrow, this could be accomplished with the interchangeable sun shields. Additionally, the interchangeable sun shields can be removed altogether, if the need for speed was a factor, like in professional racing. Since all of the eye shade portions of the sun shield helmet assembly are transparent they will not block the vision of the bicyclist. Further, the assembly can include a sticker or stickers attached to the eye shade portion, in an assortment of different colors, shapes and styles. 
     More objects and advantages of my invention will become apparent from consideration of the drawings and ensuing description.
