Abstract:
A spectacle lens design for a spectacle lens (2) to be positioned relative to the eye of a wearer according to a given as-worn position is provided. The spectacle lens design includes a clear distance zone (4), a clear near zone (5), and an intermediate zone (6) located between the clear distance zone and the clear near zone. This intermediate zone includes at least one of focusing structures providing a focal power resulting in a myopic defocus or diffusing structures (6a) leading to a diffusion of light passing the intermediate zone. According to the invention, at least one of the clear distance zone (4) and the clear near zone (5) extends over the whole width of the spectacle lens design. In addition, a computer-implemented method of designing a spectacle lens and method of manufacturing a spectacle lens are provided.
