Lenticularization is a process developed to minimize the edge thickness of a lens. The Lab defines an optimal region around the fitting cross; outside this region the software reduces the thickness with a gradual change in curvature, giving as a result a thinner lens.

* The shown examples in the table bellow have been calculated for a circular lens with a radius of 22,5mm. Data shown inside the following table indicates the edge thickness in millimetres.

Frame Shape Lenticularization

It is possible to input the frame shape data in the IOT LDS. For calculating a frame shape lenticular lens, the system applies the lenticularization in a region around the frame edge. This eliminates the need to select an optical bowl diameter for lenticularization, providing thickness reduction adapted for every frame..


Types of lenticularizations
As well as for standard lenticularization the frame shape lenticularization can be done with the Lenticular or the Lenticular Plus curvature.

Halo width
The halo width comes predefined by the software in 5mm. Nevertheless the lab can modify it. Halo width and final edge thickness of the lens are directly related. The wider the halo, the thinner the lens will be, but it will reduce the optimum visual region.
