3. PERFORM A HIGH-BASE BEVEL
This section describes the procedures for the creation of a high-base bevel:
• Description of the high-base bevel screens, (F p.33)
• Perform a high-base bevel in “automatic trajectory” mode or “front surface tracking” mode. (F p.34)
The use of the high-base bevel is determined by two parameters: frame and lens.
• Concerning the lens, the main constraint is the thickness of the nasal and temporal edges.
• Concerning the frame, the crucial elements are the bridge and shape of the groove. The hinge is an
additional factor in the case of a metal frame, the arms for a plastic frame.
For this job, the lens base must always match the frame base perfectly. Too great a difference
between the two could be detrimental to the quality of your job.
