Visual testing systems encompass a broad category based on their specific application. They include special cataract quantifiers, anomaloiscopes for color-blindness tests, and other multi-role ophthalmology testing systems. Although they differ in resolution, computer interface capabilities and intended application, they all interface with the patient through a binocular viewing port. A cataract quantifier is will detect the amount of stray-light scattered, thus detecting cataracts that may not be found by other tests. Visual testers come with multiple settings for applications such as general medical practice, optometry, pediatric and school health, or driver licensing. Look for machines that can simulate environmental conditions such as day and night, and indication of when environmental controls exceed the accepted standards.

- Features:
- 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. -
Color Vision Test -
Large selection of color 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 -
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. -
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. -
Optotypes for Children -
In addition to the tumbling-E test, additional optotypes for testing the visual acuity of children have been added. These are based on the H-test optotypes.

- Features: The examination with the C-Quant is easy and quick, for people with poor vision. The examination time is between one and two minutes per eye.
The OCULUS C-Quant measures in an accurate and objective way the amount of straylight in a patient’s eye. It is based on the "compensation comparison" method which is most comfortable and intuitive for the patients. - Tests Performed: Inquire
