Cooperative eye hypothesis Cooperative eye hypothesis The cooperative eye hypothesis is a proposed explanation for the appearance of the human eye. It suggests that the eye's distinctive visible characteristics evolved to make it easier for humans to follow another's gaze while communicating or while working together on tasks. Unlike other primates, human beings have eyes with a distinct colour contrast between the white sclera, the coloured iris, and the black pupil. This is due to a lack of pigment in the sclera. Other primates have pigmented sclerae that are brown or dark in colour. There is also a higher contrast between human skin,
Eye injury glaucoma, uveitis cataract, vitreous hemorrhage and retinal detachment. The complications risk is high with retinal tears, penetrating injuries and severe blunt trauma. Based on the injury to the eyewall(outer fibrous coat of the eye consisting of cornea and sclera) It includes A) Globe rupture:caused by blunt trauma and is an inside-out injury. B) Globe laceration:It is full-thickness wound caused by sharp objects. It includes 1)Penetrating trauma:The globe integrity is disrupted by a full-thickness entry wound and may be associated with prolapse of the internal contents of the eye. Such injuries are often referred to as a Globe fracture or a
