FIELD: physics. ^ SUBSTANCE: in one of the versions of the invention, a shifting contact lens has an optical zone, having at least two far vision zones which determine far vision optical power, and at least one near vision zone which determines near vision optical power, wherein the lens additionally has a horizontal meridian, where the value of the far vision optical power on the horizontal meridian or over the horizontal meridian is greater than 50% of the total correcting power of the optical zone, and the value of the far vision optical power below the horizontal meridian is less than 50% of the total correcting power of the optical zone. ^ EFFECT: design of shifting multifocal lenses use of which is independent of the size of the pupil and is not sensitive to the pupil. ^ 11 cl, 7 dwg |
