Ophthalmic Lens Thickness Calculation (CELO) is a system already known in the optical field that makes it possible to calculate the thickness of spherical and cylindrical lenses with practicality and speed.

Now the software has a powerful function: dynamic 3D images that help in the visualization and making of the lenses.

Another feature of CELO is the possibility of comparing the thicknesses of two different indices and thereby increasing the sales ticket for high-index lenses, as it will show customers with a high diopter index the advantage of acquiring a lens whose thickness will be thinner by fact.
