We are contractual partners of BVG and BSR in Berlin and also carry out expert assessments for all private individuals:
Driver’s license assessment for all classes
Boat license assessment
Pilot license assessment
The following examinations are required as part of the expert assessment:
Eye test
Color vision testing with color pigment charts, using a color anomaloscope if necessary
Stereoscopic vision
Visual field
Color vision is the ability of the visual system to recognize colors. Sensory cells called cones are responsible for color perception. They absorb the three different wavelengths of light: blue, green, and red.
However, when it comes to color vision, eight percent of men and one percent of women are affected by red-green color blindness, which can be congenital or acquired. Although the eyes function normally, there is a color deficiency for red or green. Red blindness, or protanopia, occurs when the red cones fail, while failure of the green cones leads to green blindness, or deuteranopia.
Those affected confuse colors or cannot see part of the light spectrum at all. Often, this color vision disorder goes unnoticed because it has been present since birth. However, misidentification of colors can have unpleasant consequences, which is why aptitude tests to determine the extent of color vision deficiency are mandatory for police officers, pilots, and professional drivers.
In our practice, we use an anomaloscope, which allows test subjects to mix the spectral colors red and green to produce yellow. This process is compared with normal values to determine the degree of anomaly. In addition, so-called pigment charts are used, on which a number composed of different color dots appears, which in turn is placed on a background of differently colored or gray color dots. A person with color blindness will then either read no number or the wrong number.
Almost 300,000 traffic accidents per year are caused by poor vision alone.
From the age of 40 onwards, our visual acuity decreases at dusk and in the dark. The aging process of the eyes leads to clouding of the cornea, lens, and vitreous body, whereby with advancing age, vision becomes similar to looking through a frosted glass pane. At the same time, sensitivity to glare increases, which can be really dangerous on wet roads and when blinded by the headlights of oncoming vehicles. By the age of 60 at the latest, one in three people are no longer able to drive a car at night, and among the over-70s, it is one in two.
Most drivers are completely unaware that their eyesight is gradually deteriorating and continue to overestimate their visual acuity.
Sometimes there is also night myopia, a form of short-sightedness that can affect both those with vision problems and those with normal vision. During the day, these people see clearly, but at night they have difficulty recognizing distant objects.
In our practice, we use a nyctometer, a night vision testing device, to test how your eyes react in twilight, darkness, and in an illuminated night situation. These results on visual acuity and contrast sensitivity provide significant information about your vision and your sensitivity to glare in the dark and determine whether you need to use vision aids when driving at night.
