ABSTRACT:
A tear-away lens for maintaining visibility through a transparent protective eye and face shield of a racing vehicle driver's helmet includes a tab portion having projections formed thereon to assist in grasping the tab portion to rapidly tear away the lens when visibility through the lens is reduced. The lenses may be stacked one on top of the other whereby they may be successively peeled or torn away from the shield as they become dirty or otherwise damaged whereby the wearer of the helmet may maintain suitable visibility through the shield. Each lens sheet except the outermost lens has its grasping tab elastically folded between adjacent sheets and disposed over a lens support on the shield.
