Abstract
Disclosed is a lens of variable optical power, characterized in that it includes: a transparent flexible lamella; a body having a ridge inscribed in a cylindrical surface; an element able to move a first portion of the lamella, which is distinct from a second portion of the lamella making contact with the ridge, so as to deform the lamella by flection; and a liquid contained between the lamella and the body. An optical assembly including such a lens and a vision-correcting device including such an optical assembly are also proposed.
