Abstract: A pair of trial spectacles for allowing a wearer to test the feeling and effect of a pair of spectacles and lenses before an actual pair is constructed. The trial spectacles include a frame member adapted to be supported on the face of a wearer having at least a first eye rim portion positioned in front of one of the eyes of wearer when the frame member is supported on the face of the wearer. The first rim portion is adapted to removably support a first lens. The first lens is horizontally slidable in the first portion so that the first lens can be horizontally adjusted to meet the wearer's visual requirements.
