FIELD: physics.
SUBSTANCE: multiple-image lens with directed prism effect is made on the facet principle from cells which are identical fragments of 90-degree sectors of spherical lenses directed by slopes in the same direction.
EFFECT: reduced thickness and weight of spectacle lenses, optimised working of the eye due to unidirectional prism effect.
