FIELD: medicine.
SUBSTANCE: ophthalmologic device contains contact lens, made with provision of rotation stability on eye and containing anterior and posterior curved surfaces, optic zone, peripheral stabilisation zone. Lens contains one or more subzones, inbuilt in at least one of anterior curves surface or posterior curved surface of contact lens in optic zone, which differ from each other by cylindrical axis. One or more subzones contain central disk, which has refraction spherical and cylindrical optical powers on nominal cylindrical axis, and a number of alternating concentric ring strips with refraction spherical and cylindrical optical powers on cylindrical axes, displaced with respect to said nominal cylindrical axis.
EFFECT: achieving and preservation of correct orientation of toric contact lenses on user's eye.
