Abstract
The present invention is generally related to the field of optical systems and/or lens attachments, and more specific to an optical system and/or lens attachment providing a switchable Optical Power Switch (OPS) controllably switchable between different states. A soft transparent material (12), for example silicone-gel is disposed onto a surface of a glass plate (10). The glass plate (10) can be moved with actuators towards a surface of a lens body (10). When the soft material element (12) is in contact with the surface of the lens body (12), this surface changes its optical feature.
