Operation
Information about the correct light intensity
The intensity of light is measured in Lux. The adaptation capa-
bility of the human eye is practically unrestricted. This can result
in that the eye requires major visual performance also if the
lighting is insufficient. If there is no, or insufficient light present,
the eye can only fulfil its viewing tasks by straining, or possibly
not at all. Affliction to the eyes is often the result. Accidents be-
come more frequent.
Using the digital luxmeter Testboy TV 335, you now have ac-
quired a product with which to check everywhere, whether suffi-
cient light intensities are actually available for the normal view-
ing tasks that are carried out daily. Seeing is the detection of
the difference between brightness and colours, shapes, move-
ment and distances. Only with the correct intensity of light can
the eye fulfil its tasks. Therefore, good light is important.
Saving is often incorrectly made with light. Dark zones attune to
being unfriendly. Allow more light. The type of lighting influ-
ences the information that the eye transmits to the brain. Direct
more light to there where accurate vision is important. There is
a risk of an accident in rooms that are darker than 30 Lux! Older
persons require more light because their visual acuity has re-
duced. A 60 year old person requires approximately twice the
amount of light as a 30 year old.
