Systems and methods herein describe an actuator control system for controlling intelligent actuated nose pad arms of a pair of eyeglasses. The proposed systems and methods receive a set of position data corresponding to a position of nose pad arms, generate a predicted set of position data for the position of the nose pad arms, transmit the predicted set of position data to pneumatic actuators coupled to the nose pad arms, capture a set of images comprising a plurality of views of the nose pad arms, generate an augmented set of position data of the nose pad arms based on the set of images, generate an adjusted set of position data based on the predicted set of position data and the augmented set of position data, and transmit the adjusted set of position data to the pneumatic actuators coupled to the nose pad arms.

Embodiments relate to an optical trial frame that includes: left and right frames extending in the left and right directions respectively; a bridge located between and connected to the left and right frames such that the left and right frames can move relative to each other along a longitudinal axis of the bridge; left and right temples connected to the respective left and right frames; left and right lens holders rotatably coupled to the left and right frames respectively and configured to receive and retain lenses in use; and, capacitive sensing means configured to detect and measure at least one of: a lateral position of one of the frames; and, a rotational position of one of the lens holders.

Improved augmented reality smartglasses ensure alignment of displays in a head-mounted wearable device such as AR smartglasses by specifying a relationship between material properties of the frame at the shoulder and nose bridge. For example, such a material relationship may be a rigidity and/or stiffness characteristic. In some implementations, the specified relationship is that a difference between the first bending stiffness and the second bending stiffness is less than a tolerance (e.g., 5%, 1%, or less than 1%).

Disclosed herein is a specialty device and tool for eye care professionals. The device of the present invention includes a top section having a plurality of temple adjusters, a viewing, a middle section that is tapered to a thinner thickness than the top section, wherein the middle section includes: a plurality of large middle marks, a plurality of small middle hashmarks, a plurality of measuring slots placed in the middle section, a bottom section that includes: a plurality of bottom temple adjusters, a plurality of large bottom marks, a plurality of small bottom hashmarks, and a plurality of bottom measuring slots.

The invention relates to a method for manufacturing an ophthalmic lens having at least one optical function, comprising the step of providing a starting optical system of the lens, having a basic optical function and the step of additively manufacturing an additional optical element of the lens, by deposition of multiple predetermined bulking components made of at least one material having a predetermined refractive index, directly onto the front surface and/or the rear surface of the starting optical system; wherein the additive manufacturing step comprises the step of determining a manufacturing guideline for the additional optical element on the basis of the characteristics of said at least one optical function to be provided to the lens, the characteristics of said at least one basic optical function, the geometric characteristics of the starting optical system, and the predetermined refractive index of the material.

A contact lens cleaner and a method for protein removal and sterilization by electrophoresis dissociation are disclosed. The contact lens cleaner comprises a lens cleaning tank (10), two electrophoresis dissociation probes (20) are arranged in the lens cleaning tank (10) opposite each other, and the electrophoresis dissociation probes (20) are electrically connected to a circuit power supply. The lens cleaning tank (10) is filled with an electrolyte solution; a lens to be cleaned is placed in the lens cleaning tank (10); and a switch is turned on, and the two electrophoresis dissociation probes (20) in the lens cleaning tank (10) form an anode and a cathode. There are lacrimal proteins on the surface of the lens to be cleaned, the lacrimal proteins are charged in the solution, and the charged lacrimal proteins move to the electrode opposite to the electrical property thereof in the cleaning tank (10) according to the phenomenon of electrophoresis. The electrolyte solution reacts chemically in the cleaning tank (10) to produce hypochlorite having a strong oxidizing property, and the hypochlorite can degrade the lacrimal proteins, and also can sterilize and disinfect.

An apparatus for cleaning surfaces can include a wiping assembly. The wiping assembly can have a pair of wiping elements, each wiping element having a wiping surface and an opposed gripping surface. The pair of wiping elements can be arranged with the respective wiping surfaces opposing each other. The wiping assembly can further include a coupling element having opposed longitudinal ends. Each longitudinal end of the coupling element can be coupled to a respective wiping element of the pair of wiping elements.

Methods and devices for determining at least one centring parameter are disclosed. A mobile terminal is moved from a first position to a second position, and a respective image is captured of an eye area of a person. The acceleration is also measured during the movement. The centring parameter is then determined based on the captured image and the measured acceleration.
