  • Patent number: 10070785
    Abstract: An eye examination apparatus comprises an illuminator adapted to project a light beam on an optical illumination path along a first optical axis to illuminate the retina of an eye, said illuminator comprising a light source and a projection diaphragm adapted to shape the light beam, during the operation of said examination apparatus said projection diaphragm being optically conjugated with the retina. Acquisition means receive light reflected by the retina and acquire images of the retina. Scanning means move the light beam projected on the surface of the retina along a scanning direction. Separation means of the beams separate the light projected by said illuminator from the light reflected by the retina. The projection diaphragm comprises a projection opening having an elongated shape and variable width, said projection opening comprising a portion having a width larger than the width of said projection opening at the first optical axis.

  • Patent number: 10042185
    Abstract: The present invention is to provide a full-frame adhesive anti-fog film structure, comprising: an anti-fog film, which has a front side and a back side opposing the front side; and an adhesive, which is disposed at an edge of the back side and arranged along the edge so as to be frame-shaped. The anti-fog film of the present invention is attachable to a planar, cylindrical or spherical lens through the full frame-shaped adhesive so that not only can the anti-fog film be fully attached to the lens but the full attachment of film also prevents bubbles from forming between the two attached surfaces. Also, an airtight space is formed between the full-frame adhesive anti-fog film structure and the lens to stop heat transfer and prevent fog from being formed, so as to not only provide good vision to users but also reduce the chance that the user will fall prey to an accident if the user's view is blocked.

  • Patent number: 10028825
    Abstract: Apparatuses, systems and methods for providing improved intraocular lenses (IOLs), include features for reducing side effects, such as halos, glare and best focus shifts, in multifocal refractive lenses and extended depth of focus lenses. Exemplary ophthalmic lenses can include a continuous, power progressive aspheric surface based on two or more merged optical zones, the aspheric surface being defined by a single aspheric equation. Continuous power progressive intraocular lenses can mitigate optical side effects that typically result from abrupt optical steps. Aspheric power progressive and aspheric extended depth of focus lenses can be combined with diffractive lens profiles to further enhance visual performance while minimizing dysphotopsia effects. The combination can provide an increased depth of focus that is greater than an individual depth of focus of either the refractive profile or the diffractive profile.
