Abstract

An optical device (1), comprising: a first optical transparent thermoplastic layer (2); a second optical transparent thermoplastic layer (3), and; in between both thermoplastic layers (2, 3); a diffractive optical element (4) adjacent to the first thermoplastic layer (2), a spacer (5) in between the diffractive optical element (4) and the second thermoplastic layer (3), and; a border (6) enclosingthe diffractive optical element (4) thereby forming a sealed cavity (7); wherein at least an upper part of the border (6), adjacent to the cavity (7) is formed from an adhesive (15).

Description

technical field [0001] The present disclosure relates to curved optics, and in particular to curved optics comprising liquids. Background technique [0002] Hypermetropia, a well-known disease in which the eye loses its ability to focus at close distances, afflicts more than 2 billion sufferers worldwide. Traditional solutions include passive lenses such as reading glasses, progressive lenses or multifocal contact lenses. However, these passive lenses typically suffer from a limited field of view, reduced contrast, or long adaptation times. [0003] Thus, refocusable lenses, which can change the focal length of a portion of the lens, have attracted a lot of attention in the field, as they would eliminate many of the known problems. Although some optomechanical solutions exist, electro-optic solutions are preferred because they are easier to reconfigure, have faster response times, and are mechanically more robust. Most electro-optic solutions require a cavity filled with ...
