Ophthalmic devices having elastic electrodes are disclosed herein. An example ophthalmic device may be an intraocular lens that includes a support structure, two optical windows, two immiscible fluids, and an elastic electrode. The support structure may have an inner surface defining an aperture with first and second optical windows disposed on opposite sides of the support structure and spanning the aperture. The two immiscible liquids may be disposed in a cavity formed by the aperture and the first and second optical windows, and the elastic electrode may be disposed on the inner surface. The elastic electrode may be formed from an elastic metal alloy having a minimum yield strain of 0.25%.

Eyeglass systems

This disclosure describes, in part, eyeglass systems configured to automatically adjust an optical-power value, or optical power, of lenses of the eyeglass system based on the distance between eyes of a user wearing the eyeglass system and an object that the user is looking at. In some instances, the eyeglass system may determine a degree-of-convergence (DoC) or convergence angle between the left eye and the right eye of the user to determine the distance between the eyes of the user and the object the user is viewing. Further, the eyeglass system may include a power source and lenses that change their optical-power value based on different voltage or current values provided to the lenses by the power source.

A method may include stretching a deformable bounding element into a stretched state. The method may further include coating the deformable bounding element with at least one layer of an anti-reflective material while the deformable bounding element is in the stretched state and assembling an optical lens assembly including the deformable bounding element, such that the optical lens assembly adjusts at least one optical property by controlling a shape of the deformable bounding element. The deformable bounding element may have less tension when in a neutral state than the deformable bounding element has when in the stretched state. The method may additionally include coating the deformable bounding element with at least one layer of an anti-reflective material while the deformable bounding element is not in a stretched state. Various other apparatuses, systems, and methods are also disclosed.

In one aspect, a device includes a frame, at least one lens coupled to the frame, at least one membrane at least partially covering at least one face of the lens, a reservoir in fluid communication with the membrane and containing fluid, and a fluid control assembly which controls fluid communication of the fluid between the reservoir and the membrane.

Variable power endoscope based on liquid lens technology

An endoscope realized as either a borescope or a fiberscope including one or more fluid filled lenses is described. In an embodiment, the optical power of the fluid filled lenses may be adjusted to adjust the focal length associated with the endoscope. Thus, variable working distances are allowable while maintaining focus on an object in front of the endoscope. The endoscope may include a distance sensor, which is used to determine a distance between the endoscope and a sample. A processor may compare the measured distance to the current optical power of the one or more sealed fluid filled lenses. The processor may transmit signals to one or more actuators coupled to one or more sealed fluid filed lenses to change the optical power of the one or more sealed fluid filled lenses based on the comparison.

LENS WITH MULTI-SEGMENTED LINEAR MENISCUS WALL

The present invention relates generally to an arcuate liquid meniscus lens with a meniscus wall. Some specific embodiments include a liquid meniscus lens with a meniscus wall essentially in the shape of multiple segments of a frustum of a cone. Embodiments may also include a lens of suitable size and shape for inclusion in a contact lens.

PULSED PLUS LENS DESIGNS FOR MYOPIA CONTROL, ENHANCED DEPTH OF FOCUS AND PRESBYOPIA CORRECTION

Ophthalmic lenses incorporate multifocal properties for the purpose of slowing, retarding, controlling or preventing myopia development or progression, correcting presbyopic vision or allowing extended depth of focus. The lens has electronically controlled adjustable focus where the change in focus oscillates so rapidly that it is imperceptible to human vision.

Fluid-filled lenses and actuation systems thereof

An actuator assembly for an adjustable fluid-filled lens is provided. In some embodiments, the actuator assembly includes a clamp configured to adjust the optical power of the fluid lens module when the clamp is compressed. In some embodiments, a magnetic element is configured to adjust the optical power of the fluid-filled lens. In some embodiments, a plunger changes the optical power of the fluid lens module.
