    摘要： Disclosed are assessment devices and methods to assess eyesight. In one embodiment, an eyesight assessment device includes a medium having one or more imaging functionalities and operable to project images for display based on the one or more imaging functionalities. The device also includes an optical source operable to project light and being positioned at one or more positions relative to the medium, such that at least one of images are projected from the medium based on the position of the optical source relative to the medium and the one or more imaging functionalities of the medium, where each image corresponds to an object provided for display at a virtual distance relative to a user of the eyesight assessment device, and where each image includes one or more of user assessable display characteristics that are indicative of a visual condition of the user.

    摘要： Systems and methods for continuous objective assessment are discussed herein. The systems and methods may comprise sensor(s), a processor, a clock, data storage, and a power source. The sensor(s) may continuously monitor viewing distances, light exposure, or the like, and the system may log corresponding time and/or duration information. Also provided herein are methods of treating, preventing, and/or diagnosing vision impairment risk. These systems and methods may provide warns, such as when detecting the viewing of materials too closely (e.g. ≤30 cm), near to near intermediate viewing (e.g. ≤70 cm) exceeding a predetermined time (e.g. ≥20 min.) without a break, and/or not getting enough outdoor light exposure (e.g. at least 75 minutes of exposure at >1000 lux) for the day.

    摘要： A method for measuring visual field comprising a reference standardized symbol display operation in which a standardized test symbol is displayed at a reference location BP provided at a center of a display 2; a reference input operation in which a test subject is made to input the fact that the standardized test symbol displayed at the reference standardized symbol display operation has been recognized; a peripheral standardized symbol display operation in which, following input of the fact that the standardized test symbol was recognized at the reference input operation, a standardized test symbol is displayed at a location different from the reference location BP; and a peripheral input operation in which the test subject is made to input the fact that the standardized test symbol displayed at the peripheral standardized symbol display operation has been recognized; wherein a response time is measured from when the standardized test symbol is displayed at the peripheral standardized symbol display operation to when the fact that the standardized test symbol has been recognized is input at the peripheral input operation.

    摘要： A system and method for ophthalmic surgery in which a portion of the light reflected by the eye passes through a lens that inverts the image and a portion of the light reflected by the eye does not pass through the lens. A digital image of both light that passed through the lens (lens image) and light that has not (peripheral image) is created using an image sensor. A processing resource identifies the boundary between the lens image and peripheral image and inverts at least a portion of either the lens image or the peripheral image to produce a corrected image in which no or only a small portion of the image is inverted as compared to the eye.
