    摘要： A Friedmann analyser with an arrangement of fixed and rotatable shutters (6, 8) for displaying different patterns of light spots to a subject has a screen (20) for displaying to the operator each light spot pattern selected by illumination of a series of light-emitting elements (22) at fixed positions over the screen area. The light-emitting elements are actuated by a fixed array of infra-red emitting and receiving elements (26) that direct radiation onto a binary-coded reflective pattern (24) displaceable with the rotatable shutter (8) and sense the radiation reflected by said pattern so that with the displacement of the shutter different reflected code signals are sensed associated with respective shutter light patterns displayed to the subject.

    摘要： The invention relates to an instrument for simulation of multifocal ophthalmic corrections, comprising two optical channels with different optical power values in the beams coming from the object observed, wherein at least one channel comprises a Badal system. This instrument simultaneously provides images of objects near and far focused. The system provides the same optical magnifications for each channel, regardless of the optical power thereof, and produces superimposed retinal images with different degrees of focus which, unlike other devices, are all of the same size. The instrument allows simulating different optical powers for near vision and different refractive corrections for distant vision.

    摘要： System and methods for testing and/or training a subject's visual perception span and/or speed are provided. More specifically, a method may include testing/training various aspects of the subject's visual perception span/speed through the use of assessments that test the subject's ability to receive and retain information that is flashed in front of them. By using various assessments, an efficient examination may be administered. In accordance with the invention, an individual may be subjected to such a method of testing/training comprising: presenting one or more two-dimensional representations to the subject at a first time; receiving input responses from the subject at a second time; and processing the received input responses to provide a measure of the perception span of the subject; and processing the time between the first time and the second time to provide a measure of the perception speed of the subject.

    摘要： Through the present invention, a perimetry result is obtained for a position on a retina surface designated as a position to be tested. As illustrated in the drawing, "the position of a ganglion cell (RGC)" and "the position of a photoreceptor cell (C) for sending information to the ganglion cell (RGC)" are offset on the retina surface (macular part). Here, when position (P1) is designated as a test position for testing the functioning of a ganglion cell at position (P1), the perimeter of the present invention finds "the position (P2) of the photoreceptor cell for sending information to the ganglion cell at position (P1)," presents a visual target at position (P2) rather than position (P1), and tests a visual field. The information of the visual target is sent to the ganglion cell at position (P1), and the functioning of the ganglion cell can therefore be tested. The test result is correlated with the position (P1) and displayed, and the ganglion cell at the designated position (P1) can be therefore be tested.
