The R17 Pro's 24 million photosensitive units, designed with a large 1.4 ?m pixel size and 1/2.55 photosensitive area for enhanced photoreception
. OPPO's OIS optical stabilization technology means you'll never have to strain to steady your hand, leaving you free to reach for that perfect glimpse wherever it beckons.
It has been suggested that non-visual photoreception
may influence developmental processes in mammals (Rao et al., 2013), and there are findings suggesting that in mammals, melanopsin (a family of light-sensitive proteins) expressing cells are primarily located at the level of the retina, but have been able to maintain their functional connection with neuro-endocrine cells for the control of mood, as melanopsin gene variants and polymorphisms correlate to increased risk of developing seasonal affective disorder (SAD) (Roecklein et al., 2013).
This viewpoint is only now evolving with our growing understanding of mammalian circadian photoreception
in the retina and the important role of melanopsin , which is a short-wavelength (blue) sensitive opsin expressed by a subset of retinal ganglion cells that project directly to the SCN via the RHT.
Light during darkness and cancer: Relationships in circadian photoreception
and tumor biology.
The aim is to provide a comprehensive examination of photosensitivity in this well-studied xiphosuran that may provide key insights into photoreception
in euchelicerates and the evolution of photosensitivity among chelicerates and arthropods in general.

Biological effects of light are called also the non-visual effects of light, related to the human circadian photoreception
. The biological effects of light and their effects on human performance are not yet very well known.
It therefore seems that NIF visual functions can be supported by photoreception
in either rods and cones or ipRGCs.
The primary function of ipRGCs is non-image-forming photoreception
, for mediating the PLR via signaling to the pretectal olivary nucleus  and for the signaling of environmental irradiation to entrain the central body clock to the solar day to maintain the circadian rhythm.
rerio ZEM-2S cells are also photosensitive, glucocorticoids seem to be as relevant as light to regulate photoreception
and the circadian system.
