FIELD: physics.
SUBSTANCE: full range of multifocal lenses is made by using three aspherical back surfaces, which are symmetrical with respect to rotation, the structure of the basic curves of which is a function of the refractive power.
EFFECT: design of multifocal contact lenses, which are simple to make but are comfortable during use and are provided with means of correcting presbyopia.
