Progressive CAFE 3x
FreeForm LDS

Basic version of the most advanced LDS software by COMES, CAFÉ 3x allows the realization of 3 Progressive designs with 3 channel lengths for each design, + 3 Degressive / Anti-fatigue designs.
The License of use of the 3x version provides a fixed purchase cost and it is totally free of royalties (FREE click).

PROGRESSIVE CAFE LENS DESIGN SYSTEM – A NEW ROAD TO MAKE PROGRESSIVE SURFACES

Progressive CAFE calculation and analysis software arises from the desire to develop an innovative product that is distinguished from what is already present on the market, for the ability to offer the user the opportunity to “draw” their own design and immediately evaluate the result obtained through a powerful integrated dioptric analysis tool.

The user will be able to create, modify and study endless completely personalized and unique designs, and then offer a line of products designed to satisfy even the most diverse needs that the market may require.

COMES also provides a series of ready-to-use designs, to allow a quick start of production. These designs are the 3 characteristics designs (outdoor, indoor and generic) with the freedom to choose the length of the progression channel (variable at discretion).

Value added

•  No royalty required version / Free Click
•  It works with every index of refraction.
•  It works for any mounting height.
•  Tailor-made parametric design, ready-to-use parameter sets provided by COMES.
•  Arrows calculated using continuous parametric functions, guaranteed solution for every combination of the sphere, cylinder, axis, addition, length of the progression channel, etc.
•  VCA standard compliant.
•  Transparent interface with COMES Z-Lab LMS and the best third-party LMS (LensWare International – compatible).
  

Main features
