  • Patent number: 5710613
    Abstract: Artist's eyeglasses having a clear section in the lens and a diffused section in the same lens suited for viewing an object to be painted or drawn through the diffused section and seeing that object in its most basic shape, shifting one's gaze away from the object to the painting medium (canvas) and simultaneously shifting one's eyes to the clear section while the basic shape is fresh in the mind, and transferring that basic shape onto canvass. The glasses also have adjustable shading and lighting shields over the frame and temple arms to permit the artist to vary the shading and lighting at the point of perception as best suited for artistic needs and purposes.
