Document Summary

Somehow a distorted and upside-down 2-d retinal image is transformed into the. No species can see in the dark, but some are capable of seeing when there is little light. Light can be thought of as: particles of energy (photons, waves of electromagnetic radiation. Light enters the eye through the pupil, whose size changes in response to changes in illumination. Sensitivity the ability to see when light is dim. Acuity the ability to see details. Lens focuses light on the retina. Ciliary muscles alter the shape of the lens as needed. Accommodation the process of adjusting the lens to bring images into focus. Convergence eyes must turn slightly inward when objects are close. Binocular disparity difference between the images on the two retinas. Both are greater when objects are close provides brain with a 3-d image and distance information. Interspecies difference: retina and translation of light to neural signals.
