  • Publication number: 20230367038
    Abstract: A contact lens having antioxidant properties is described as well as methods of manufacturing the same. The contact lens can be present in a sealed contact lens package. The seal contact lens package can include at least a) a plastic base member having a cavity; b) a contact lens packaging solution in the cavity; c) a sterile, unworn contact lens immersed in the contact lens packaging solution in the cavity; and d) a cover that forms a liquid-tight seal with the plastic base member. As an example, the unworn contact lens is a silicone hydrogel contact lens having present therein vitamin E. The vitamin E is non-releasable from the unworn contact lens and the contact lens packaging solution has less than 1 ppm of vitamin E present. The vitamin E is trapped, embedded, absorbed, or non-covalently attached in the unworn contact lens.

  • Patent number: 11196902
    Abstract: There is described an apparatus including a camera defining an azimuth axis. A swing supports the camera. The camera is rotatable relative to the swing about the azimuth axis. A yoke is rotatably coupled to the swing about a tilt axis. The swing is rotatable relative to the yoke about the tilt axis. A locking member attached to the swing is movable between a first position and a second position in which the locking member contacts the camera.

  • Patent number: 10612663
    Abstract: There is described a multi-headed camera comprising a camera base, multiple camera heads coupled to the camera base, each camera head comprising a camera lens defining an observation angle, each camera head being configured to pivot such that the observation angle may vary between a minimum observation angle and a maximum observation angle, and a protective shield attached to the camera base, extending over the camera heads and shaped such that for each camera head a distance between the shield and the camera head varies as a function of the observation angle. Attached to each camera head is a resiliently deformable and flared gasket positioned around the camera lens and extending toward the shield. The gasket is configured such that, for any observation angle between the minimum and maximum observation angles, the gasket contacts the shield about a closed light seal path for preventing light from passing between the shield and the gasket, and reaching the camera lens.

  • Patent number: 10383417
    Abstract: A case is provided for holding one or more contact lenses. The case is configured to receive an inner pod, and the case includes an upper part and a lower part. The upper part is structured to move relative to the lower part from an open configuration wherein the upper and lower parts are at least partially separated to a closed configuration wherein the upper and lower parts are together. The upper part is also structured to move relative to the lower part from a disengaged position to an engaged position wherein, in the disengaged position, the case is movable between the open and closed configurations and in the engaged position, the case is locked in the closed configuration.

  • Publication number: 20190154879
    Abstract: Silicone hydrogel contact lenses are packaged in a packaging solution including an ophthalmically-acceptable concentration of a surfactant to provide a contact lens having a lower coefficient of friction compared to a control lens that is not packaged in the surfactant. The surfactant is a poly(ethylene oxide) (PEO)-containing surfactant having a molecular weight of up to about 6,000 daltons, or is an alkyl aryl-containing surfactant, or is both an alkyl aryl and PEO-containing surfactant having a molecular weight of up to about 6,000 daltons. Methods of manufacturing silicone hydrogel contact lenses are also described.
