Abstract
The invention relates to a lens element (1) intended to be worn by a wearer, comprising at least one prescription portion (2) having a first optical function configured to provide a dioptric correction of an eye of the wearer when the lens element (1) is worn by said wearer based on a prescription of the wearer, and a plurality of lenslets (3), each lenslet (3) of said plurality of lenslets being configured to provide at least one second optical function which differs from the first optical function,wherein each lenslet (3) has a shape, a size and a position such that at least one portion of said lens element (1) has a modulation transfer function (MTF) whose values are configured so that the modulation transfer function of said lens element 1 over a range of spatial frequencies comprised between 1 and 5 cycles per degree are lower or equal to 0.6.
