Eyeglasses are a set of lenses mounted in a frame, used to correct faulty vision, dating from the 14th Century. Period eyeglasses used thick circular lenses; the frames were either tied in place with ribbons, or else held in place by the hand for reading. The illustration shows the latter type, as found in the arms of Latini, c.1550 [BSB Cod.Icon 268:243].
Eyeglasses are normally solidly tinctured, i.e., the frames and lenses are one tincture. If the lenses are of another tincture, they must be explicitly blazoned, e.g., “a pair of eyeglasses argent lensed vert”. If the lenses are removed, so that the field shows through, the charge may simply be blazoned “eyeglass frames”. See also mask.
