ABSTRACT:
A device for protecting the eyes by preventing incoming sunlight from falling upon the eyes includes a lens-free eye shade frame having detachable and interchangeable shades of different sizes and shapes attached to the frame and biased outward and extending horizontally from a wearer's face. The eye shade frame includes biasing members arranged on the front portion of the frame just above the wearer's eyes proximate the wearer's eyebrows for permitting adjustment of the shades on the frame by the wearer. The biasing members have engaging ends which are wedge shaped such that shades which engages the biasing members are biased horizontally outward from the wearer's face and are resiliently retained on the frame. The eye shade frame includes rearwardly extending ear extensions attached to the front portion of the frame which may be inwardly foldable. The foldability of the eyeshade frame and the resilient attachment of the shades to the frame permit easy storage in a case despite the outward arrangement of the shades on the frame.
