rho·dop·sin

 (rō-dŏp′sĭn)
n.
Any of a class of reddish, light-sensitive pigments found in the retinal rods of the eyes of terrestrial and marine vertebrates, consisting of opsin and retinal. Also called visual purple.

[rhod(o)- + Greek opsis, sight; see -opsis + -in.]

rhodopsin

(rəʊˈdɒpsɪn)
n
(Biochemistry) a red pigment in the rods of the retina in vertebrates. It is dissociated by light into retinene, the light energy being converted into nerve signals, and is re-formed in the dark. Also called: visual purple See also iodopsin
[C20: from rhodo- + -opsis + -in]

rho•dop•sin

(roʊˈdɒp sɪn)

n.
a bright red photosensitive pigment found in the rod-shaped cells of the retina of certain fishes and most higher vertebrates: it is broken down by the action of dim light into retinal and opsin.
[1885–90; rhod- + Greek óps(is) sight, vision + -in1]

Fortunately, a flavonoid compound present in many berries called cyanidin-3-glucoside (C3G) is particularly beneficial for night vision, (25,26) because it stimulates the regeneration of rhodopsin.
In the quantum mechanical treatment, photon(s)- rhodopsin interaction will be associated to the existence of 'off-diagonal' terms in the density matrix representation, which are responsible for pre- serving coherence in the molecular structure of rhodopsin.
Based on its amber spectral content, this layer of amber LEDs does not disrupt our eye's melanopsin receptors and thereby eliminates circadian difficulties, as well as allows our eyes to maintain dark adaptation by not bleaching rhodopsin.
Therefore, the current study was carried out to determine the effects of NiONP on the visual functions of the vertebrate eye including visual processes, ERG b-waves, and rhodopsin regeneration using ERG techniques.
