Abstract
The present invention relates to an ophthalmic holding mechanism for holding an eyeglass frame. The holding mechanism includes a base, a clamping mechanism configured for releaseably securing a lens mount of an eyeglass frame, and an actuator operatively associated with the clamping mechanism for causing linear and rotational movement thereof. The clamping mechanism is moveably coupled to the base for linear and rotational movement about an axis of rotation relative to the base, wherein the clamping mechanism is rotatable about first and second spaced pivot points. The present invention also relates to a method of tracing a lens mount of an eyeglass frame.
