Preventing unsuitable materials being used for Rimless lenses.

Preventing unsuitable materials being used for Rimless lenses.



It is common request received that some materials are prevented from being used for rimless lenses.

To achieve this, there is a new setting entry to allow the material / index to be defined. The material index is defined as O1555 or O1740 where O = Organic/Plastic and 1555 = 1.555 index. Multiple entries are made with the semi-colon separator. For example O1555;O1556 will block both 1.55 and 1556 index.
