FIELD: physics, optics.
SUBSTANCE: contact lens comprises a lens optical area, a peripheral area surrounding the lens optical area, and stabilising areas located in the peripheral area of the lens. The stabilising areas are asymmetrical with respect to the horizontal axis. In a first version, orientation of the stabilising areas is 10.0 degrees from the vertical, and a large part of each stabilising area is above the horizontal axis. In a second version, the greatest lens thickness is located on the 0-180 degree meridian and the rate of change of the inclination of said areas differs in the direction from the highest point of the lens thickness.
EFFECT: improved contact lens stabilisation.
