  • Patent number: 8656602
    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.

  • Patent number: 8630731
    Abstract: The present invention is directed to a method of calibrating drill depth of an ophthalmic processing device. A number of drill cycles are selected for drilling an expected number of holes in a lens blank. The selected number of drill cycles is performed. The drill depth of each consecutive drill cycle varies incrementally. An actual number of locations the drill bit contacted the lens blank during the drill cycles is compared to the expected number of holes. The drill depth is adjusted depending on the compared values. A method of calibrating drill hole size is also disclosed.
