Information on the Correct Luminance
The luminance is measured in lux. The adaptability of the hu-
man eye is almost unlimited. This easily leads to demanding of
the eye visual performance even if the illumination is not suffi-
cient. If there is no light or the illumination is not sufficient, the
eye can fulfil its visual performance only with great effort or
even cannot see. Very often, this involves eye injuries the num-
ber of accidents increases.
With the Digital Luxmeter Testboy TV333 you acquired a prod-
uct by means of which you can verify everywhere if the lumi-
nance is sufficient for the normal visual performance (i.e. every-
day tasks). Eyesight means the detection of brightness and col-
our differences, form, motion as well as distance. Only with the
correct luminance, the eye can fulfil its visual performance.
Therefore, sufficient illumination is so important. Concerning
light, we often save at the wrong end. Dark zones give an un-
friendly atmosphere. Allow yourself more light.
