Detailed Information

 

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.


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.


 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.


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.
