  • Patent number: 10966607
    Abstract: Techniques for measuring optical aberrations of the eye are disclosed. An example method comprises positioning the eye in a measurement location adjacent to a measurement arm of an optical coherence tomography (OCT) interferometer apparatus, so that source light from the measurement arm passes into the anterior segment of the eye and detecting an interference pattern, the interference pattern resulting from a combination of light reflected from the eye and light reflected from a reference arm of the OCT interferometer apparatus. Based on the interference pattern, an optical delay between a reference surface in the anterior segment of the eye and a measured surface in the eye is calculated, the reference surface being the anterior surface of the cornea or the lens, wherein said calculating comprises measuring an optical phase shift between the reference surface and the measured surface, based on the detected interference pattern.

  • Patent number: 10456072
    Abstract: An image interpretation support apparatus includes a line-of-sight detecting unit that detects a line of sight of a person who reads the image, a gaze determining unit that determines, in accordance with a detection result obtained by the line-of-sight detecting unit, whether a candidate lesion portion in an image to be interpreted that is displayed on a display unit has been gazed at by the person who reads the image, a completion detecting unit that detects completion of image interpretation, by the person who reads the image, of the image to be interpreted that is displayed on the display unit, and a display control unit that, in a case where the completion detecting unit detects the completion of the image interpretation and the gaze determining unit determines that the candidate lesion portion has not been gazed at, switches from a first display state to a second display state.

  • Patent number: 10390696
    Abstract: Methods for presenting dynamic images to a user, configured to evaluate and/or improve the user's foveal and/or peripheral visual acuity. Dynamic computer games are popular, but the moving images of prior art dynamic computer games are not suitable for improving visual acuity. To overcome this restriction, embodiments of the present invention analyze user's responses to the moving images to determine a change in the user's visual acuity, and responsively adjust parameters of the moving images, such as speed, direction of motion, orientation, crowding, contrast, and spatial frequency, in order to improve the user's visual acuity.

  • Patent number: 10386657
    Abstract: A system and method for determining the measurements needed to fabricate prescription eyeglasses. The system and method take into account how the frames fit naturally on the head and how the person's posture orients the head and alters the line of sight through the lens of the eyeglasses. A sensor unit is provided that is attached to the eyeglass frames. The individual then wears the eyeglass frames and moves through at least one situational simulation. The sensor unit generates data that corresponds to changes in orientation. The data is used to determine how a person's line of sight is altered by the anatomy of the face and the posture of the head.

  • Patent number: 10373592
    Abstract: A display system divides a screen into regions and applies a different set of rendering/encoding parameters to each region. The system applies a first set of parameters to a first region that is being viewed by a fovea of an eye of a user. The system may also apply a second set of parameters to a second region that is being viewed by a parafovea of the eye, and apply a third set of parameters to a third region that is being viewed by the area of the eye outside of the parafovea. The first set of parameters are selected to yield relatively high image quality, while the second set of parameters are yield intermediate quality, and the third set of parameters yield lower quality. As a result, the second region and the third region can be rendered, encoded, and transmitted with less computing power and less bandwidth.

  • Patent number: 10317672
    Abstract: A system for tracking eye location is disclosed. Systems in accordance with the present invention include a scanner for sweeping a first optical signal across the surface of an eye, a detector for detecting a second optical signal reflected from the eye, and a detection circuit for determining a maximum intensity in the second optical signal. In operation, the scanner sweeps the first optical signal over the surface of the eye while the detection circuitry determines a plurality of intensity maxima in the second optical signal. The time between the intensity maxima during the sweep is indicative of the location of the cornea within the eye surface.
