  • Publication number: 20250160638
    Abstract: A mixed reality display headset is provided. The mixed reality display headset includes a display controller configured to receive and to store a retinal map including a boundary indicating an area to be modified within the patient's vision, to receive an image from a camera, to generate an image distortion map including shifting image data located within the boundary outwardly along a plurality of rays starting at an estimated center point of the area to be modified within the patient's vision to outside the boundary such that the image data from the center point to an edge of the image is compressed from the boundary to the edge of the image, to modulate the image based on the image distortion map to produce an intentionally distorted image, and projecting the intentionally distorted image onto the user's retina in the user's usable field of vision.

  • Patent number: 12237074
    Abstract: A method of at-home monitoring of eye conditions using a head mounted display that is capable of establishing a visual model associated with a patient. The visual model may include data related to a quality of the patient's vision. The patient may use the system to establish a visual model periodically, such as daily, and the system may compare the visual model to previous visual models and send an alert to the patient's physician if changes meeting a given criteria are detected. This may allow the physician to immediately take steps to save the patient's eyesight where a delay in treatment may result in vision loss.

  • Patent number: 12137974
    Abstract: Techniques related to vision correction are disclosed. The techniques involve establishing a visual model associated with a patient. The visual model includes data related to a quality of the patient's vision. A boundary is established as a function of the data associated with the visual model. The boundary is indicative of an area to be corrected within the patient's vision. A retinal map is established as a function of the boundary. An image from a camera associated with the patient is captured and corrections are applied to the image based on the retinal map to generate a corrected image. The corrected image is presented to the eye of the patient.
