Macropinna microstoma is a ray-finned fish with transparent head shield. Can reach up to 6 inches in length. Has green lenses and fluid-filled shield protecting sensitive eyes. Body covered in large scales and tiny mouth
Fish eyes have spherical lenses and focus by moving lens closer or further from retina. Retina contains both rod cells for low light and cone cells for color vision. Some fish can see ultraviolet and some are sensitive to polarized light
Roger M.N Clark's research shows human eyes need 576 megapixels for full field of view. Human eyes can only move about 180 degrees. Fovea contains about 7 megapixels of visual information. Average field of view is 120 degrees
Adult human eye measures 24.2mm x 23.7mm x 22.0-24.8mm. Pupil size varies from 2 to 8mm in diameter
Eye contains over 2 million parts that process light and interpret visual information. Six paired cranial nerves supply sensory and motor innervation to eyes. Visual system receives, processes, and interprets visual information
The eye contains three layers: outer, middle, and inner. It has three fluid chambers: anterior, posterior, and vitreous. The eyeball is made up of cornea, sclera, and the retina
