<p>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: Formula (I) where a5 is other than 0 and at least one of the coefficients a6, a7 and a8 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: Formula (II) where mi, is the value of said optical property at a specific viewing angle β with respect to the optical axis of the lens, and αi is a weighting value. The optical properties can be calculated using, for example, ray tracing.</p> |
