Stub? Really
[edit]This article is more complete than many that do not claim to be stubs. I think stubbitude has expired.Dodger (talk) 22:17, 14 December 2008 (UTC)
Animals using their eyes...
[edit]The claim made on this page about dogs being one of only two species looking to others' eyes is absurd! — Preceding unsigned comment added by 124.183.250.163 (talk) 12:41, 20 August 2012 (UTC)
Humans with naturally dark sclera
[edit]I think it's worth mentioning in the article that many individuals with dark skin exhibit naturally dark sclera (usually of a yellowish or brown tint, but sometimes orange), and this is a natural, benign condition. There are relatively few references on it, and this is on of the only I have ever come across: http://www.knowswhy.com/why-do-africans-have-yellow-eyes/
I've also read this is due to an excess of melanin in the eye, which is why you primarily see it in individuals with very dark skin, which seems more likely than the claim it's due to subconjunctival fat. Sadly, the most common reference I've found (mainly in old texts) is that this some "primitive" trait comparing it to the dark sclera of gorillas (which are usually jet black), even though one can observe it in very dark skinned humans across the world, even in non-africans. It would be helpful if someone could incorporate more extensive, verifiable references on this, if they do exist. — Preceding unsigned comment added by 98.110.235.68 (talk) 01:26, 10 September 2014 (UTC)
Yes, normalizing white anatomy in this way is an obvious case of systemic racial bias in Wikipedia. I have added some more language, but citations and review by someone with expertise would be helpful. Vectro (talk) 14:17, 27 May 2018 (UTC)
Gorillas' scleras are not usually totally black: "They looked at a sample of 85 gorillas from two species. Out of the 60 western lowland gorillas they considered, only 30% had completely dark scleras. The remaining 70% had some degree of white in their eyes. Of these, a small sample of 7% had all white, human-like sclera, just like Nadia and Bana, below." http://www.bbc.com/earth/story/20150808-gorillas-with-human-eyes https://www.researchgate.net/publication/274642518_Gorillas_with_white_sclera_A_naturally_occurring_variation_in_a_morphological_trait_linked_to_social_cognitive_functions Extremophile (talk) 02:03, 4 December 2020 (UTC)

Exaptionist or alternative explanations on why the human sclera is more exposed
[edit]Compared to apes, the human ocular cavity has a wider aperture, thought to allow for an ample field of vision, quickly scanning a wider terrestrial environment with more efficiency than rotating the whole head. The article does not even mention the sclera, but it's sort of inevitably implied, as we would not be able to look through it: https://www.nature.com/articles/srep11528 Extremophile (talk) 01:57, 4 December 2020 (UTC)
