In technical terms, all humans have 'hunter eyes,' i.e., forward-facing eyes that allow them to focus on and pursue prey, like what is found among other predatory animals. Hunter eyes can be considered the opposite to 'prey eyes,' that is, eyes that are located on the skull's side that aids prey animals in spotting potential threats in their peripheral vision. | In technical terms, all humans have 'hunter eyes,' i.e., forward-facing eyes that allow them to focus on and pursue prey, like what is found among other predatory animals.

Hunter eyes are likely a [[sexual dimorphism|sexually dimorphic]] trait. Vertically narrow, i.e. a high width-to-height ratio (with a low level of vertical scleral show) is considered the essential aspect of 'hunter eyes'.<ref>https://lookism.net/threads/whats-great-about-orbs-eye-area-in-lookism-terms.68363/</ref> | |||
In Caucasians, men's eyes have a greater width-to-height ratio than women's, while women's eyes are rounder,<ref name="daniel2020">https://link.springer.com/article/10.1007/s00265-020-02894-1</ref> i.e. more [[neoteny|neotenous]]. The same sex difference has been found in Asians and Africans.<ref>Hajnis K, Farkas LG, Ngim RCK, Lee ST, Venkatadri G (1994) Racial and ethnic morphometric differences in the craniofacial complex. In: Farkas LG (ed) Anthropometry of the Head and Face, 2nd edn. Raven Press, New York, pp 201-218</ref> | |||
The sex of human skulls can also be identified based on whether the eye sockets are more round or more square.<ref>https://www.futurelearn.com/info/courses/forensic-facial-reconstruction/0/steps/25656</ref> | |||
Though, the correlation between the eye's width-to-height ratio and global facial masculinity was close to zero and non-significant in one study,<ref name="daniel2020"></ref> suggesting it is not uncommon for men to have hunter eyes without having a particularly masculine face in general, despite the feature itself being sexually dimorphic. | |||
Women's round and cute eyes are closer to 'prey eyes'; however, women have a smaller interpupillary distance than men, rather than their eyes being peripherally positioned like in prey animals.<ref>https://pubmed.ncbi.nlm.nih.gov/8115125/</ref> | |||
