  • Patent number: 10018852
    Abstract: An eyeglass positioning device configured to be positioned between a user's nose and eyeglasses frame to elevate multifocal lenses relative to a user's eyes to bring an intermediate or near field of vision into a line of sight for use with certain activities, such as computer use, when the user's head is in an upright and normal head tilt position. The eyeglass positioning device preferably comprises a connector and two support arms that simply sit on a user's nose in either an upright or an inverted orientation, providing greater flexibility of use and comfort. The eyeglass positioning device may be used with a variety of shapes, styles, and sizes or eyeglass frames without requiring attachment to the frames or obstructing the field of view through the lenses.

  • Patent number: 9888839
    Abstract: Methods and apparatuses for determining contact lens intolerance in contact lens wearer patients based on tear film characteristics analysis and dry eye symptoms are disclosed. In embodiments herein, imaging of the ocular tear film is performed during contact lens wear. An analysis of the image of the ocular tear film is performed to determine one or more tear film characteristics of the ocular tear film. The tear film characteristics can be used to determine the effect or possible effect of contact lens wear on the ocular tear film, and thus be used to determine contact lens intolerance of the patient. The tear film characteristics used to analyze contact lens intolerance based on images of the ocular tear film involving contact lens wear may include dry eye symptoms, including but not limited to tear film (e.g., lipid and/or aqueous) thickness, tear film viscosity, and tear film movement rate in the eye.
