FIELD: physics, optics.
SUBSTANCE: optical lens comprises front curved lens with outer and inner arc-shape surface, rear curved lens with inner and outer arc-shape surfaces. Cavity is composed by inner surfaces of front and rear curved lenses for physiological solution and oil to make the meniscus there between. Meniscus wall is the area in meniscus cavity from inner side of said front curved lens wherein liquid meniscus boundary passes and features truncated cone shape a part of which is at least convexed along optical axis.
EFFECT: friendly use in eye, decreased variation of optical force at preset level of stress.
