FIELD: optics.
SUBSTANCE: ophthalmic lens comprises front and rear curved lenses, each of which has external and internal surfaces of arched shape, cavity between them containing volume of physiological solution and volume of oil, forming liquid meniscus boundary between them, meniscus wall formed in front curved lens and having general shape of flattened cone, concave along direction of optical axis, and first fold, adjoining meniscus wall containing first angular element to limit position of contact between external peripheral edge of boundary between liquid meniscus and meniscus wall.
EFFECT: technical result is improved control of meniscus movement.
