  • Variable power optical element
    Patent number: 9001282
    Abstract: A variable power optical element is divided into cells which contain two liquid crystals mixed according to different proportions. The proportion of one of the liquid crystals in each cell increases on the basis of the radial distance between a central point of the optical element and said cell. An appropriate selection of the two liquid crystals results in a higher variation of the optical power between two control states of said optical element. More particularly, the optical element may consist of an ophthalmic lens which changes between a convergent lens state and a divergent lens state.
