A Superlative Vision-Screening Instrument

The Binoptometer® 4P is a professional screening instrument for testing all relevant visual functions. The 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.

  • 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 in. In addition, the viewing angle is fully adjustable up to a 35° downgaze, thus enabling testing to be done ergonomically with any eyeglasses.

Visual Acuity Test

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

New: Now also ETDRS Charts are available for the visual acuity test.

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.

New: Due to additional corrective lenses in the range of -0.5 D to -3.5 D the possibility to check night myopia is now available.


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.

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.

Additional Corrective Lenses

If asthenopic symptoms are present or if the visual acuity values are abnormal, the additional corrective lenses in the range of +4,5 D to -3,5 D can be used to determine whether an undetected (latent) hyperopia (up to +1,5 D), an age-related long sightedness (presbyopia) or myopia, especially night myopia, exist.

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.

Refractive Test

The red-green bi-chrome test and astigmatism chart allow fast screening for significant refraction errors.

Improved Color Vision Tests
ETDRS Charts
In addition to the already familiar, short results overview, you can now get a more detailed presentation of the results, visual acuity, color vision test and the Amsler test. Here, you get an overview of all of the answers given by the patient.

  • The list of pre-programmed examination programs can be customized according to your requirements. The order of the programs can be changed and examination programs that you don’t need can be hidden.
  • Custom programs can be created and existing programs can be copied and edited.

The instructions for use of the original Ishihara, Velhagen and Matsubara color chart tests state a time within which a chart should be read. To ensure reliable results, we have now also implemented this recommendation in the Binoptometer® 4P. You have the option to activate this function.
For the visual acuity test the well-known ETDRS charts (based on the Early Treatment Diabetic Retinopathy Study) are now available in the Binoptometer® 4P.

Optional Accessories

Mesopic vision testing under true-to-life conditions

The external light shield of the Binoptometer® 4P permits mesopic vision tests independent of room conditions. It protects the eyes against incident light, allowing examinations also to be conducted in bright rooms.

Transport Trolley for Binoptometer® 4P

The convenient trolley provides the maximum protection for your Binoptometer® 4P. With its smooth-running castors and pull-out handle, this transport trolley is the ideal helper for your mobile use of the unit.

Carrying Bag for Binoptometer® 4P

This practical carrying bag can comfortably hold your Binoptometer® 4P and all of its accessories, such as netbook or control unit, test blocks and cables.
