mesopic vision and photopic vision can be neglected when the luminance is
higher than 0,1 cd/m2. In other words, for practical purposes, the lower limit of the
zone of photopic vision may be put at 0,1 cd/m2. (d) The Purkinje-shift The fact
that ...

For the moment it is sufficient to know that the human retina has two classes of
visual photoreceptors, one class operating when light is plentiful, in what are
called photopic conditions (cone photoreceptors) and the other operating when
light is ...

Photopic® Imaging Since sonographic examinations are usually performed in
darkened rooms, the examiner relies on scotopic perception with the retinal rods,
which have sensitivities from 0.0001 to 10 cd/m2. This "black-white" perception ...
These functional studies measured photopic and scotopic sensitivity at matched
retinal locations in the same cohort of well-characterized eyes. The studies had
large samples, involving 106 normal subjects from seven decades of adulthood ...

Optometry: Science, Techniques and Clinical Management
However, the situation is complicated by the fact that the retina contains two
different types of photoreceptor. As a result, under photopic ('bright') conditions,
when the retinal cones are the dominant receptors, the efficacy curve (Vl) peaks
at ...

Light Pollution Handbook
There is not one single luminance value where photopic vision and scotopic
vision meet. In contrary, there is a wide ... Because it is between photopic and
scotopic vision, it usually called the zone of mesopic vision. The reason that the
zone of ...

Measurement, Instrumentation, and Sensors Handbook, Second ...
At high illumination levels, corresponding to photopic vision, the eye perceives
color due to the excitation of three different types of cone receptors. There is
considerable overlap in the spectral sensitivity curves of these red, green, and
blue ...
