Abstract
Eyewear having easily removable lenses is provided with a frame that defines a first lens receiving recess on one side of a lens opening and a second lens receiving recess on a second side of the lens opening. Each lens has a first tab portion which corresponds with the first recess and a second tab portion which corresponds to the second recess and is mounted by placing the first tab portion in the first recess and the second tab portion in the second recess. Engagement between the respective tab portions and recesses maintains the lenses in the mounted position. To more securely lock each lens in position, a pivot member having a locking tab can be pivoted into a locking position in which the locking tab engages the lens.
