  • Publication number: 20210106218
    Abstract: A visual field device includes a light source and an eyepiece. The light source includes a backlight arranged to generate, in use, light directed towards a first liquid crystal display (LCD) screen and a second LCD screen, the first LCD screen and the second LCD screen overlapping one another and the backlight such that the light source outputs light transmitted through both the first and second LCD screens. The eyepiece is arranged between the light source and a subject position, the eyepiece being configured to receive light output by the light source and focus the received light towards the subject position. Each of the first and second LCD screens include a respective array of pixels, each pixel being controllable so as to vary its transmittance to light generated by the back-light.

  • Publication number: 20150378067
    Abstract: An actuation mechanism for simultaneous actuation of first and second variable focal length lenses is disclosed. Each lens comprises a distensible membrane bounding a fluid-filled cavity, the focal length varying with the degree of curvature of the membrane as it distends. The actuation mechanism comprises a hydraulic master actuator in fluid communication with a hydraulic slave actuator associated with the first lens and with a hydraulic slave actuator associated with the second lens. Each slave actuator is configured to vary the degree of distension of the membrane of its associated lens in response to operation of the master actuator, whereby the master actuator is operable to cause a variation of the degree of distension of the membranes of both the first and second lenses simultaneously.

  • Publication number: 20140347581
    Abstract: Aspects of the present invention provide an electro-active lens and method for manufacturing the same that encapsulates liquid crystal using solid transparent optical material using an improved liquid crystal seal feature. The seal feature greatly reduces the visibility of the liquid crystal seal feature in an assembled electro-active lens. The seal feature is also structurally robust such that the electro-active lens can be processed to fit a spectacle frame without disturbing containment of the liquid crystal and without disrupting electrical connectivity to the lens used to alter the refractive index of the liquid crystal, thereby ensuring fabrication of a commercially viable electro-active lens.

  • Patent number: 8739785
    Abstract: An inhalation device comprising a base having a slot for insertion of a single blister containing a dose of medicament to be inhaled into the base is disclosed. The inhaler has a mouthpiece pivotably mounted to the base which carries a blister piercing element operable to pierce a blister received in said slot when the mouthpiece is pivoted relative to the base. When a user inhales on the mouthpiece, the dose is entrained in an airflow and flows out of the blister through the mouthpiece and into the user's airway.
