Eyeshades are a type of eyewear that is designed to block out light and provide protection from the sun. They are typically made of a dark material such as leather or plastic, and often feature a curved shape that covers the eyes and part of the face. The term 'eyeshades' can also refer to the PIGMENTS used to color the lenses, the LIDS that hold the lenses in place, and the visors that are attached to the frames.
