Calculation Technologies > Surface Power

 


This is the basic level of technology that only considers a fixed, non-tilted lens, tangential rays, infinitely small pupil and replaces the eye by a constant remote sphere. This method is based on a pure geometrical conception of the lens; mixing curved surfaces the lens will provide final wearers with the power that will correct their ametropy in a central gaze direction. Nevertheless, this technology does not take into account any customization, and as a result, the final lens is not optimized for each wearer. The Power and Addition are what we call Nominal.

These kinds of designs are basic designs, and according to this, we recommend our customers to position the lenses produced with this technology in the basic segment, as a basic product.
