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.
The 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.
Contrast sensitivity, optional mesopic vision and glare sensitivity testing with just one instrument.
Convenient height adjustment range of 10.5 cm (4.3 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.
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.
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.
