FIELD: physics.
SUBSTANCE: multi-focus lens has an optical element, having a surface which has at least one bifocal diffraction structure and one trifocal diffraction structure. The bifocal diffraction structure is configured to provide near and far sight and the trifocal diffraction structure is configured to provide near, far and intermediate sight.
EFFECT: design of trifocal intraocular lenses which provide intermediate vision without worsening far and near sight.
