Binoptometer®4P

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.

The OCULUS Test Strategies

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.

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.

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.
