Progressive Lens Design calculations have progressed significantly, moving from simple, first-order approximations to complex, computer-aided simulations. Get familiar with LENSEEK’s three major technologies used to calculate and design progressive lenses.
Every LENSEEK progressive lens design is available using our three core technologies: 5C, APDAPT, and FORMAT. This allows customers to create three distinct products from each design, addressing different needs, requirements, and price points.

The 5C lens calculation technology is used to produce complex lens designs. It is LENSEEK’s regular calculation method for creating premium lenses suitable for all users.

The ADAPT lens calculation technology represents an advanced approach to superior lens design computation. Developed by LENSEEK, this sophisticated system is engineered to deliver outstanding wearer comfort and quality.

The FORMAT lens calculation technology builds upon the ADAPT calculation method, incorporating frame shape data into the process. As LENSEEK’s most advanced calculation technology, it enables the creation of individualized exceptional products designed to deliver an unparalleled wearer experience.
