FIELD: medicine.
SUBSTANCE: method of designing a multifocal lens involves the stages of specifying a rest pupil size, calculating a pupil size when observing a close target, specifying the relations of far vision correction area to close vision correction area for a lens, calculating the relation values as a function of total optical power when observing close and far targets with using the rest and close pupil diameters, and optical convergence for the lens is added.
EFFECT: creation of the multifocal contact lenses relieving intensified eye accommodation and using the advantages of residual eye accommodation amplitude.
