Abstract
A set of goggles comprising a lens holder including a pair of confronting straps having aligned lens apertures therein which receive lens. The straps are coupled together along the bottom, side and outer top confronting edges but are separated at a central, upper passage which is wider than the width of each lens but narrower than twice the width of each lens. Mechanism is provided for detachably coupling the lens holder to headgear, such as a helmet or a bandanna, and includes side bands that are coupled to opposite ends of the straps and extend along the sides of the head of a user. The bands can be detachably coupled to complementally formed fasteners provided on the helmet or bandanna. The side bands include forward portions folded over upon themselves and coupled to the ends of the straps. A rotary, side band adjustment bar is mounted on each end of the strap between the folded portions for adjusting the relative vertical positions of the side bands and the straps to adjust the relative pressures exerted by the upper and lower portions of the straps on the face of the user.
