Abstract
Abstract A lens holder having a pair of spring connected clamping members with apertures therein mountable over a lens socket of spectacle frames. The clamping members have an extent which is sufficient to completely span lens sockets and extend a distance beyond. Transverse lateral rulings on at least one of the clamping members permit gauging an aperture in a clamping member relative to a socket in a spectacle frame. In this manner, geometrical characteristics of a test lens may be measured and recorded for the purpose of making permanent lenses for a selected spectacle frame. In addition to transverse lateral rulings on a clamping member, angular rulings about an aperture in a clamping member may also be applied for determining angular orientations of a test lens.
