and framed lenses; bifocal, multifocal, and progressive lenses.
You can also take prism measurements.
The LensChek Pro allows you to perform pupillary distance
(PD) measurements, and check the ultraviolet (UV) light trans-
mittance.
Note: Before you measure a lens, verify that the instrument
lens under the Lens Stand is clean. Use a lens cleaning
cloth or a soft, dry, clean cotton cloth to clean it.
