ABSTRACT:
A polarized lens is mounted to a helmet having a transparent face shield to cover a top portion of the face shield and reduce glare in the user's field of vision. In the preferred embodiment of the invention, the polarized lens does not cover the lower portion of the transparent face shield so that the user's primary field of vision can be adjusted to pass through the uncovered lower portion of the transparent face shield when the user tilts their head back slightly. The lens is preferably attached to the helmet using hook and loop fastener. On a sunny day, a helmet wearer, e.g. a snowmobiler or a motorcycle rider, can attach the polarized lens to reduce glare, and can tilt their head back slightly if the sunlight disappears temporarily (e.g. when the vehicle passes into the woods). In addition, the user can easily remove the polarized lens if the sunlight disappears for an extended time.
