Abstract: A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.

Abstract: A device and method for providing stimulation signals that reset the phase of the neuronal activity of neurons in a patient's brain. The device includes a control unit; and a stimulation unit that has a plurality of stimulation elements, and each stimulation element generates visual stimulation signals that reset the phase of the neuronal activity of the neurons when the signals are taken up via an eye of a patient and transmitted to neurons that are exhibiting a pathologically synchronous and oscillatory neuronal activity. The control unit is further capable of actuating the stimulation unit such that the stimulation elements generate the visual stimulation signals with a time offset in respect to one another and/or with differing phase and/or with differing polarity.
