Deformable spectacle lenses.
Although there are many designs of progressive power multifocal lenses commercially available, they all follow the same basic design concept, with the lens power varying across their aperture as a result of using one aspheric lens surface. An alternative approach was tried on an experimental basis, where the variation in power is produced by a liquid-filled deformable lens.
