Lens Design: Rotationally symmetric, geometrically symmetric or asymmetric front and back surfaces with atoric spherical effect optics
Materials: GP: most common materials; Soft: Polymacon Benz 3x (48%) and Benz 5x (58%)
Optical Design: Single Vision, Multifocal (center distance, center near or segmented), Aspheric Toric, Aspheric Bitoric with front surface prism, Reverse geometry (GP only)
Compound Optics: Combine multiple elements (multifocal, toric, bitoric, and reverse geometry) into one design, even a spherical center with a toric periphery!
Power Range: Sphere +/- 30 diopters, Cylinder +/- 30 diopters, Add +0.25 - 5 diopters
Dimensions/thickness Control:
GP - Diameter 8.5 -15mm, center thickness 0.12-1.0mm,
edge
thickness 0.10 - 0.30mm; Soft -
Diameter 13 - 15mm, center thickness 0.08 -1.0mm, edge
thickness 0.10 - 0.30mm
Design Controls: Initial Rx, over refraction, compound over refraction, diameters of optical zone, intermediate zone, edge, bevel
Tear Film / Zone Diameter Control: Rotational designs: drag and drop global control of zone diameters and tear film clearance of optical zone, intermediate zone, bevel and edge, 360 degrees around the lens. Asymmetric and Geometrically symmetrical designs: drag and drop control of zone diameters and tear film clearance of optical zone, intermediate zone, bevel and edge at 8 individual meridians controlling a 90,180 or 360 degree segment of the lens.
