Patent

CA 2223031

In the field of eyesight correction, there is a need for "universal" spectacles that can be tailored in situ to suit individuals~requirements. The disclosure relates to an apparatus, which may be in the form of a pair of spectacles (10) including one or m ore liquid lenses (11a, 11b). The apparatus also includes a sealable duct (24) and a pump (e.g. a syringe) for adjusting the pressure of liquid in the liquid lens. In use, the apparatus is adjusted to provide eyesight correction for an individual. The duct (24) is then sealed, thereby rendering the apparatus subsequently non-adjustable and therefore permanently tailored to the requirements of the individual. The disclosure also relates to an apparatus in the form of a flexible membrane mirror.

Dans le domaine de la correction de la vision, il existe une demande de lunettes polyvalentes qu'on peut adapter sur place afin de répondre à des besoins individuels. L'invention concerne un dispositif qui peut se présenter sous la forme d'une paire de lunettes (10) comprenant une ou plusieurs lentilles liquides (11a, 11b). Ce dispositif comprend également un conduit pouvant être obturé (24) et une pompe (par exemple, une seringue) servant à régler la pression du liquide contenu dans la lentille. Pendant l'utilisation, le dispositif est réglé pour corriger la vision d'un individu. On obture ensuite le conduit (24), ce qui supprime, par conséquent, la possibilité de réglage du dispositif et adapte ce dernier en permanence aux besoins individuels. L'invention concerne également un dispositif sous forme d'un miroir à membrane souple.
