English to French Tech/Engineering Engineering (general) electronic spectacles

This invention relates to electronic spectacles for patients having trouble with eye-accommodation (presbyopia, accommodation spasm, patients after cataract surgery etc…). More specifically, this invention relates to ophthalmic lens or lenses.

An ophthalmic lens for spectacle comprisinga membrane: the membrane comprises a deformable portion, the deformable portion, partially comprised in the main chamber totally separates the main chamber in at least a first chamber configured to comprise at least a primary fluid and a second chamber configured to comprise at least a secondary fluid, the first chamber is comprised between the second primary surface and the deformable portion, the second chamber is comprised between the deformable portion and the first secondary surface.

At one given position of the deformable membrane 400, its radius of curvature will coincide with the radius of curvature Rsep of the separation surface between the two halves. The choice of that particular position (corresponding to either focus near or focus far) may be left to the product design.
