Good faith edit

I quit feeling like it was all about death but hey, someone had to make it this way. More personal information about give and take and that vision exists in your mind due to Biology and the Brain. — Preceding unsigned comment added by 2602:301:7751:160:1D1C:5C29:ED0:86C0 (talk) 13:05, 4 September 2016 (UTC)[reply]

More information about the 'vision that exists in the mind' can be found in the article Visual perception. That article is mentioned in the 'See also' section, but it deserves more prominence in this article. Apuldram (talk) 18:35, 4 September 2016 (UTC)[reply]

Photosensitive ganglion cells

Intrinsically photosensitive retinal ganglion cells are now known to be involved in conscious vision in rats.^[1]
There are more opsins at work in various IPRGCs than just melanopsin (no citation for that, sorry). We likely do not have the full story there yet: from what I can tell, the full complement of retinal neuron types has not been cataloged.
Similarly, there are about 15 axon types within the optic nerve (I've seen higher numbers in some publications). It is not known what each is for; color, brightness and movement only account for a few.
Humans with normal vision do seem to use melanopsin information within their color perception.^[2]

I'm not sure exactly how the article needs to change because it isn't clear that there's scientific consensus regarding melanopsin's role in conscious human vision. But there must be some consensus by now - those refs are from 2010 and 2012!
