Automatic initialization
Optical tracing:
• tracing of tinted lenses
• automatic tracing pattern, demo lens, recut lens in 2 dimensions
• pre-positioning of drill-holes and their settings on a demo lens or a recut lens
• recut lens: equivalent sphere [-1D; +1D]
The lenses with an infra-red filter cannot be read.
Manual centering:
• single vision lenses: using focimeter dots or re-marked micro-engravings
• progressive lenses: using re-marked micro-engravings or manufacturer markings
• bifocal and trifocal lenses
