Document Summary

Determines its hue: dimension of colour determined by the wavelength of light. Wavelength: distance from the peak of one light or sound wave to the peak of the next. Intensity: the amount of energy in a light or sound wave. Iris: a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening. Lens: transparent structure behind pupil that changes shape to help focus images on the retina. Focuses incoming rays of light into an image onto the retina via a process called accommodation by changing curvature. Accommodation: the process by which the eye"s lens changes shape to focus near or far objects on the retina. Retina: light-sensitive inner surface of the eye containing the receptor rods and cones plus layers of neurons that begin the processing of visual information. Retinal receptors that detect black, white and gray; necessary for peripheral and twilight vision when cones don"t respond.
