Abstract
The invention relates to an optical element having adjustable focal length, and a method for producing an optical element. The optical element comprising a first transparent layer and a transparent soft polymer having a chosen refractive index situated thereon, said layer being made from a material having a chosen flexibility, e.g. a thin glass layer, the optical element also being provided with an actuator for applying a force upon said flexible layer, said force being essentially symmetric relative to said axis thus bending the layer providing a lens surface and providing a curved refractive surface.
