  • Patent number: 10679518
    Abstract: This disclosure relates to an electronic device for compensating for a visual impairment. The electronic device comprises a display to display a graphical user interface to a user and an input port to receive a request for modifying the graphical user interface to compensate for a visual impairment of the user. The device further comprises a processor to modify the graphical user interface to compensate for a visual impairment of the user by replicating an optical effect of one or more optical lenses. A visually impaired user can operate the device because the processor modifies the interface to compensate for the visual impairment. Without the modification of the interface, it would be difficult for the user to operate the device because the visual impairment causes the interface to appear blurred.

    Abstract: My invention is an automated self-testing method utilizing binary choice, which is applicable to monocular and binocular eye tests and can be administered on computer, cellular phones, and other electronic devices. Binary choice of match or no match, yes or no, present or absence provides simple means of automated testing by stepwise progression through staircase algorisms. Necessary devices have been introduced in order to fully utilize the power of binary choice self testing, such as, (1) printed display overlays for testing fine visual acuity at near, (2) bright illuminator of printed overlays to allow automated potential vision testing, (3) the use of complementary color lenses and color test isopters for binocular perimetry.

  • Publication number: 20150009475
    Abstract: Aspects are disclosed for determining refractive error. In an aspect, a line pattern is displayed to a user, and a distance between the line pattern and the user is ascertained. The line pattern includes a first and second line in which an aspect of the line pattern is varied, and where refractive error is quantified based on the distance and a selected variance of the line pattern. In another aspect, the varied aspect of the line is at least one of a width between the first and second line, a thickness of the first or second line, a darkness of the first line or the second line, or a color of the first line or the second line. An input corresponding to a focused line pattern variance selected by the user is then received, and a refractive error is quantified based on the input and an approximate distance between the line pattern and the user.

  • Publication number: 20140340645
    Abstract: A viewing target for a visual acuity and refraction measurement includes at least one line comprising a width dimension that is below a resolution limit width (hereinafter “RLW”) of a test subject visual acuity, and an adjustable length dimension that is initially set at greater than the RLW of the test subject visual acuity. A base, at least approximately intersecting the line, has a thickness along the direction of the length of the line that is greater than the RLW of the test subject visual acuity. The length dimension of the line is adjustable in increments small enough to effectively approximate the visual acuity of the test subject by determining a shortest resolvable line and a next smaller line that is not resolvable by the test subject.

  • Patent number: 8864312
    Abstract: A method of testing visual performance includes determining a difficulty rating for each of a plurality of visual recognition tests. The method further includes displaying one of the visual recognition tests to a subject and receiving from the subject a response to the visual recognition test. After receiving the response to the visual recognition test, a subsequent visual recognition test is selected to have a difficulty rating determined based on the response received from the subject, the subsequent visual recognition test is displayed, and a response is received from the subject. The subsequent visual recognition tests are repeated until a predetermined number of responses is reached. A visual performance score is determined based on the set of responses received from the subject and the difficulty ratings for the visual recognition tests displayed to the subject is then output.

  • Patent number: 8814360
    Abstract: Disclosed are a method and kit for testing visual acuity in a subject. The examiner displays a test thread at a set distance in front of the subject's face, and then determines whether the subject grabs or looks at the test thread. These steps are repeated using subsequent threads of varying thickness. The smallest thread to which the subject responds is charted as their best VA in standard notation. The visual acuity of a young child can be quantified using standard adult Snellen acuity levels. The device can be used worldwide, as it transcends language barriers, and in a variety of practice settings, including pediatric ophthalmologist offices, general ophthalmologist offices, optometric offices, pediatricians and family doctors who see young children or persons unable to read a conventional Snellen chart and/or verbalize their responses.

  • Patent number: 8814355
    Abstract: System and methods for testing and/or training a subject's visual ability are provided. More specifically, the method may include testing various aspects of the subject's visual acuity, such as clarity, contrast, tracking, etc. By using various tests, a more efficient examination may be administered. In accordance with the invention, an individual may be tested using methods of testing and/or training at a unitary center, where the unitary center is capable of presenting visual tests to the individual, receiving input from the individual, and processing the received input. Such a unitary test center may further be configurable, so that the tests administered may vary based on the needs of the individual. The received input may then, for example, be used to compute data related to the user's visual acuity, both overall and for each individual test.
