Abstract
Lens assemblies and goggles are disclosed. One example goggle includes a lens assembly. The lens assembly includes a lens and a ventilation shutter configured to cover vent openings of the lens in a first position and expose the vent openings of the lens in a second position. The shutter has substantially the same transparency as the lens and is slidably attached to the lens by a button. The button extends from an exterior lens surface through the lens to an interior lens surface and has a button end configured to extend through the shutter.

A goggle, comprising:
- a lens having first surface and a second surface opposite of the first surface, the lens further having a plurality of vent openings and having a button opening elongated in shape;
- a button configured to fit and slide in the button opening, the button having a portion extending through the lens from the first surface to the second surface and terminating in a button end;
- and
- a shutter having a plurality of vent openings and a button attachment opening, the shutter proximate the second surface of the lens, the button end configured to extend through the button attachment opening, the vent openings of the shutter overlapping the vent openings of the lens with the button in a first position and the vent openings of the lens covered by the shutter with the button in a second position.
