5.5.1.4. Driving Contrast Sensitivity Test
The test must be conducted in binocular vision, with bare eye
or with correction in case of refractive vice. A line is
considered read when two out three letters or three out five
are correctly recognized. In case of subjects with lenses,
affected by advanced preosbia a better correction with the
addition of + 1.00 diopter might be needed.
For the driving licenses of group 1 is required at least the
reading of the line corresponding to the logaritmic value of
1,20 (Log. CS), indicating contrast threshold of about 6%
(0,063).
For the driving license of group 2 is required at least a reading
of the line corresponding to the Log. CS 1,50 indicating a
contrast threshold of about 3% (0,032).
