The disclosure relates to an optical article comprising an optical lens shell having an internal surface, a support element mounting said shell, disposed in a fixed position, and movably mounting a moveable element between a first position and a second position. The optical article further comprises a sealed cavity, placed between the moveable element and the internal surface of the shell. The optical article is switchable between a first configuration, in which the moveable element is passively held against the shell and a second configuration, in which the cavity is filled with a predetermined amount of a fluid altering the propagation of visible light and the moveable element is released from the shell by the pressure exerted by the fluid in the cavity. The disclosure also comprises a corresponding method for controlling said optical article.

Ophthalmic devices and ophthalmic systems including alignment sidewalls and blend zones disposed therethrough are described. An example ophthalmic device may include a first and a second optical element having alignment sidewalls shaped to cooperatively couple. The alignment sidewall may include blend zones disposed in the sidewall shaped to transition the sidewall from a ridge to a surface of an optic zone of the optical element. The alignment sidewalls may define a cavity disposed between two coupled optical elements when the alignment sidewalls are cooperatively coupled into which a liquid crystal may be disposed. A method of assembling an ophthalmic device is described. An example method may include aligning a blend zone of a first optical element with a mating blend zone of a second optical element. The example method may further include cooperatively coupling alignment sidewalls of the first optical element and the second optical element.

The invention relates to a tunable lens where the optical power can be adjusted. The lens consists of a deformable, non-fluid lens body sandwiched between a thin, flexible membrane and transparent back window, and an actuator system serving to change the overall shape of the membrane and lens body. The membrane is pre-shaped to have a Sag or Sagittal of at least 10 μm so that the lens has a non-zero optical power when the actuator system is not activated. In order to achieve a large optical power range for the lens, the membrane should preferably be made of a material having a Young's modulus in the range 2-1.000 MPa.

An apparatus having an asymmetric adjustable lens with a deformable optical element. The apparatus may also include one or more actuators coupled to a deformable element of the asymmetric adjustable lens in a direct-drive configuration such that (1) mechanical action of the one or more actuators applies force to the deformable optical element and (2) the force applied by the mechanical action of the one or more actuators changes an optical property of the asymmetric adjustable lens by deforming the deformable optical element. Various other devices, systems, and methods are also disclosed.

A focus adjusting tool used to perform an initial setting for a pair of autofocus eyeglasses includes an adjusting lens that refracts reflected light from a visual object, a housing including an inner space that allows a parallel movement of the adjusting lens, an adjusting unit that adjusts a position of the adjusting lens inside the housing, and a first end and a second end in a moving direction of the adjusting lens. The first end is provided with a hole for visually observing a visual object through a power variable lens of the pair of autofocus eyeglasses. The adjusting lens adjusts, in response to the position thereof inside the housing, an incident angle of the reflected light from the visual object into the power variable lens, the visual object being located on the side of the second end.

A pair of eyeglasses having two-part upper rim portions. One part is made of a flexible material and the other part is made of a rigid material. The flexible portion can be pulled away from the rigid part by a user, allowing a user to interchange lenses without the use of any tools.

The present disclosure concerns a tuneable ophthalmic lens 200. The tuneable ophthalmic lens comprises an activated state and a deactivated state. The ophthalmic lens further comprises a central chamber 206b. The ophthalmic lens also comprises a fluid reservoir, the fluid reservoir being in fluid communication with the central chamber. The fluid reservoir comprises a pump for pumping fluid between the fluid reservoir and the central chamber. In the deactivated state the central chamber is substantially empty of fluid 208a. In the activated state the central chamber is not substantially empty of fluid.

A membrane assembly 150 for a variable focusing power optical assembly 100 is disclosed. The membrane assembly 150 comprises a distensible membrane 155 that is held under tension around its periphery (boundary B) by at least one bendable support ring 159 and one or more bending actuators 170, each comprising a selectively operable self-bending strip, which are attached contiguously to respective discrete sections of the support ring 159 for actively controlling the curvature of those sections of the support ring 159. Also disclosed is a variable focusing power optical assembly 100 comprising such a membrane assembly 150. Further disclosed is an article of eyewear 80 comprising at least one such variable focusing power optical assembly 801.

The spectacle lens includes a lens substrate; a multilayer film disposed on one surface of the lens substrate; and a multilayer film disposed on the other surface of the lens substrate, wherein an average reflectance within the wavelength range from 380 to 500 nm measured at least on one surface of the spectacle lens is 10.00% or more, and a reflectance measured at least on one surface of the spectacle lens is 5.00% or less in the entire range within the wavelength range from 400 to 780 nm.
