THREE-STATE OPTICAL ARTICLE AND METHOD FOR CONTROLLING SAME

The disclosure relates to an optical article which comprises a hollow chamber (100) and a separator (102) separating the hollow chamber (100) into a first subspace (100a) and a second subspace (100b).The separator (102) comprises an aperture (103).The optical article comprises a deformable membrane...

Zusammenfassung:The disclosure relates to an optical article which comprises a hollow chamber (100) and a separator (102) separating the hollow chamber (100) into a first subspace (100a) and a second subspace (100b).The separator (102) comprises an aperture (103).The optical article comprises a deformable membrane (200), attached, in the second subspace (100b), along a closed line surrounding the aperture (103).The optical article is switchable, by deformation of the membrane (200), between at least three states (ST1, ST2, ST3).Each state corresponds to a different optical function.The disclosure also comprises a corresponding method for switching said optical article between at least two of the three states.
