Multifocal contact lenses manufactured from a responsive polymer gel

Abstract

A multi-focal contact lens wherein the lens is manufactured at least partially from a responsive polymer gel.

Description

technical field [0001] The present invention relates to lenses such as contact lenses, intraocular lenses, implantable lenses, inlay lenses, inlay lenses or any other ocular refracture device. For ease of reference, these lenses will be collectively referred to as "contact lenses" and accordingly, any reference to "contact lenses" (plural), "contact lenses" (singular), "lenses" (plural), "lenses" (singular) etc., will include at least the lenses described above. [0002] In one embodiment, the invention relates to bifocal or multifocal contact lenses formed from so-called smart polymers. Background technique [0003] As the popularity of contact lenses surpasses the use of eyeglasses to correct vision, there is a need to address the problems experienced by users who seek to correct their vision, including nearsightedness and farsightedness. There is therefore a need to develop bifocal, preferably multifocal, contact lenses. [0004] Examples of embodiments of bifocal cont...

Problems solved by technology

The disadvantages of compromised vision are similar for both lenses, plus the significant loss of light makes imaging at night more problematic than with refractive contact lenses
