Document Summary

Perception: the selections, organization, and interpretatory of sensory output. Form of radiation that travels as a wave. Measured in amplitude (height) and wavelength (distance between peaks) Purity: how varied the mix of amp and wave is. Perception of saturation (relative amount of whiteness) Cornea and lens create upside down image. Lens: transparent eye structure that focuses the light rays falling on the retina. Accommodation: when the curvature of the lens adjusts to alter visual focus. Close: lens of your eye gets fatter (rounder) Nearsightedness: close objects are seen clearly but distant are blurry. When cornea or lens bends light too much or eyeball is too long. Farsightedness: distant objects are seen clearly but close appear blurry. Pupil: opening in the center of the iris that helps regulate the amount of light passing into the rear chamber of the eye iris : colored ring of muscle surrounding pupil. When constricts: less light but sharpens retina (bright)
