"Procedimiento de diseño y de fabricación de una lente oftálmica monofocal y lente correspondiente"

The invention relates to a method for designing and manufacturing a monofocal ophthalmic lens and corresponding lens. In the method for designing a surface of a monofocal ophthalmic lens, the surface is defined by an analytical function such as: f x y = a 1 + a 2 ¢ 1 - a 3 ¢ x 2 - a 4 ¢ y 2 + a 5 ¢ exp a 6 ¢ x 4 + a 7 ¢ y 4 + a 8 ¢ x 2 ¢ y 2 where a 5 is other than 0 and at least one of the coefficients a 6 , a 7 and a 8 is other than 0, such that it includes a hyperbolic component and an exponential component. The coefficients can be calculated by means of an iterative calculation and a merit function such as: fm = ˆ‘ i ± i m i 2 ² 1 / 2 where m i is the value of said optical property at a specific viewing angle ² with respect to the optical axis of the lens, and ± i is a weighting value. The optical properties can be calculated using, for example, ray tracing.
