    OCULUS Binoptometer® 4P

    Price:  $0.00

    A Superlative Vision-Screening Instrument

    The Binoptometer® 4P is a professional screening instrument for testing all relevant visual functions. The used future-oriented technology allows an almost unlimited representation of various vision tests. 

    Vision-screening instrument with contrast sensitivity testing and optional mesopic vision and glare sensitivity testing.


    Highlights

    New Test Presentation

     

    Vision tests are presented on a high-resolution micro-color display, allowing a virtually unlimited presentation of vision tests.

    Unbeatable

    Contrast sensitivity, optional mesopic vision and glare sensitivity testing with just one instrument.

    Ergonomic

     

    Convenient height adjustment range of 4.13 inch (10.5 cm). In addition, the viewing angle is fully adjustable up to a 35° downgaze, thus enabling testing to be done ergonomically with any eyeglasses.

    Functions

     
       

    Visual Acuity Test

    With Landolt rings (in acc. with DIN EN ISO 8596), numbers, letters, tumbling E (optional) and acuity symbols for children (optional).

    Colour Vision Test

    Large selection of colour plates according to Ishihara and Velhagen-Broschmann colour test plates. The display is calibrated to the exact color temperature, thus guaranteeing ideal color rendering.

    Binocular Test

    The binocular vision tests are generated by a modern LCD shutter system, which is very similar to natural visual conditions. Furthermore, a variety of stereo-vision and phoria tests guarantees a reliable evaluation of the binocular vision functions.

    Contrast Sensitivity Test

    A program for testing contrast sensitivity under photopic conditions is also integrated. The contrast sensitivity test can be conducted at various visual acuity levels with Landolt rings, letters and numerals as options.

                 

    Mesopic Vision and Glare Sensitivity (Optional)

    Visual performance varies in different light conditions. To test visual function under mesopic conditions, a Landolt ring is presented in an environment of low light density (0.032 cd/m²), corresponding to the situation of night driving. The Landolt ring (visual acuity level 20/200) is presented in four different contrast stages (1:23 / 1:5 / 1:2.7 / 1:2). Glare sensitivity is tested by simulating the dimmed light of an approaching vehicle. The test with this glare light is also conducted in the four contrast stages.

    Peripheral Visual Field Test

    The visual field is tested at seven visual field locations at the right and at the left. Fixation control is done by means of a changing fixation mark in the center of the test screen.

    Hyperopia Test

    If asthenopic symptoms are present or if the visual acuity values are abnormal, especially in the near vision area, this test can be used to determine whether an undetected (latent) hyperopia or age-related far-sightedness (presbyopia) exists. This test can be done at all distance settings.

    Range of Accommodation Measurement

    Measurement of the range of accommodation can be a valuable tool for deciding whether special eyeglasses for computer users are needed. The Duane test figure makes a speedy and informative measurement possible.

    Optotypes for Children

    In addition to the tumbling-E test, we have added additional optotypes for testing the visual acuity of children. These are based on the H-test optotypes.
