Abstract RU 2580875 C2

FIELD: physics.

SUBSTANCE: optical lens comprises front and rear curved lenses having inner and outer curved surfaces. The front and rear curved lenses form a cavity, having a physiological solution and oil volume, which form a meniscus in between, and a meniscus wall situated on the outer side of the front or rear curved lens in said cavity and bordering with the meniscus. The meniscus wall has a general shape from a plurality of torus segments, caved-in from the optical axis.

EFFECT: high stability and reproducibility of control of movement of the liquid meniscus when electrical current is applied to a portion of the meniscus wall.
