Abstract: Systems and methods for assessing the visual acuity of person using a computerized consumer device are described.

Abstract: A method for a purchasing interface is described. In one embodiment, the method includes initiating an order for a prescription, prompting a user to capture a photo of the prescription, and fulfilling the order for the prescription upon receiving input based on capturing the photo of the prescription. The order for the prescription is initiated from an application executing on a computing device and the photo of the prescription is captured using a camera connected to the computing device.

Abstract: A computer-implemented method for color correcting images captured using a mobile computing device is described. A wavelength of light is emitted from a display of a mobile computing device. An image of the emitted wavelength of light is captured using a camera on the mobile computing device. The image of the wavelength of light emitted from the display of the mobile computing device that is captured using the camera on the mobile computing device is analyzed. At least one image captured using the camera on the mobile computing device is modified based on the analysis of the image of the wavelength of light emitted from the display of the mobile computing device.

Abstract: A computer-implemented method for generating a three-dimensional (3-D) model of a user. A plurality of images of a user are captured via a rear-facing camera on a mobile device. A 3-D model of the user is generated using the plurality of images of the user captured using the rear-facing camera and 3-D data derived from processing a previous plurality of images of the user prior to capturing the plurality of images. A point of interest in at least one of the plurality of images captured via the rear-facing camera may be identified and the identified point of interest in at least one of the plurality of images may be correlated with one or more vertices from the 3-D data.

Abstract: A computer-implemented method for generating a three-dimensional (3-D) model of a user. A first set of images are captured. Prior to capturing a second set of images the first set of images are processed using a 3-D modeling process, resulting in 3-D data and scaled data derived from the first set of images. The second set of images are captured after processing the first set of images. A second 3-D model of the user is generated using the second set of images of the user and the 3-D data derived from processing the first set of images. A feature of the user is tracked in real time based at least in part on the 3-D data derived from processing the first set of images.

Abstract: A reusable holder for contact lens cases includes a base, at least one receptacle formed in the base configured to receive a contact lens case, and a time keeping device formed in the base. The time keeping device may include an indicator for the at least one receptacle that indicates a period of time that has lapsed since the contact lens case currently in the at least one receptacle was placed therein to denote a need to discard the contact lens case and a contact lens associated with the contact lens case.

Abstract: A contact lens package that is reusable as a case to store a contact lens between uses includes a bottom member having a well with an inside generally concave shape, and a wall rising above the well and ending in a top rim defining an opening; a temporary seal comprising a moisture-proof film sealed across the top rim to seal the opening, thus defining a volume within the package, the volume containing a contact lens and contact lens fluid; and a cap secured to the bottom member covering the temporary seal, the cap being removable to give access to the temporary seal and replaceable on the bottom member thereafter to provide storage of the contact lens between uses thereof.

Abstract: A contact lens package that is reusable as a case to store a contact lens between uses includes a lid, a base, one or more receptacles for a contact lens case, and a time keeping device. The time keeping device comprises an indicator for each one or more receptacles that indicates a period of time that has elapsed since the contact lens case currently in the receptacle was placed therein. When the period of time has expired, the indicator denotes a need to discard both the contact lens case and a contact lens associated with the contact lens case.
