  2. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    One basic model describing the geometry of the optical system is the Arizona Eye Model. [2] This model describes the accommodation of the eye geometrically. Photons of light falling on the light-sensitive cells of the retina ( photoreceptor cones and rods ) are converted into electrical signals that are transmitted to the brain by the optic ...

  3. Mammalian eye - Wikipedia

    en.wikipedia.org/wiki/Mammalian_eye

    The structure of the mammalian eye owes itself completely to the task of focusing light onto the retina. This light causes chemical changes in the photosensitive cells of the retina, the products of which trigger nerve impulses which travel to the brain. In the mammalian eye, light enters the pupil and is focused on the retina by the lens.

  5. Visual system - Wikipedia

    en.wikipedia.org/wiki/Visual_system

    In the visual system, retinal, technically called retinene 1 or "retinaldehyde", is a light-sensitive molecule found in the rods and cones of the retina. Retinal is the fundamental structure involved in the transduction of light into visual signals, i.e. nerve impulses in the ocular system of the central nervous system.

    The resulting eye is a mixture of a simple eye within a compound eye. Another version is a compound eye often referred to as "pseudofaceted", as seen in Scutigera . [ 28 ] This type of eye consists of a cluster of numerous ommatidia on each side of the head, organised in a way that resembles a true compound eye.

  8. Globe (human eye) - Wikipedia

    en.wikipedia.org/wiki/Globe_(human_eye)

    The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve.

  9. Scleral spur - Wikipedia

    en.wikipedia.org/wiki/Scleral_spur

    The spur is an annular structure composed of collagen in the human eye. It is the origin of the longitudinal and circular fibres (which swerve acutely from the spur to run circumferentially, as a sphincter near the periphery of the lens) [1] of the ciliary muscle, and is attached posteriorly to the trabecular meshwork.
