Most current engineering designs of ophthalmic progressive addition lenses operate by setting conditions on interest's points in the progressive lens surface.

Optical power conditions and desired astigmatisms are established with this points using an algorithm known as B -Splines. However, the lens surface is a continuous topography in which the gaps located in the middle of the interest's points are solved by interpolation. That means a loss of control over optical astigmatism and optical power in most of the lens' surface.

After 6 years of R & D, with the challenge of developing a mathematical model that takes into account the entire surface of the lens with infinite points, not just capable of preventing the interpolation process but also to improving the current designs, is how we reach to the exclusive "Continuum Profile Technology".

This technology allows to mold the optic surfaces with infinite control points by developing different customised designs of ophthalmic lenses that can adopt different characteristics according to each user providing a better result in the user's comfort and in the breadth of all fields of vision.

The kind of technology previously mentioned was developed to be used in Freeform Technology production equipment under the VCA protocol, allowing Novar lenses to be in a distinguished and reduced International Group.
