emmetropia Ans: optical state of the eye in which parallel light enters the eye and focuses on the retina without the need for any corrective lenses or accommodation; this is the absence of refractive error and the "normal" or ideal state of the eye ametropia Ans: refractive error, "abnormal" optical state of the eye in which parallel light rays enter the eye and focus on an area other than the retina; this condition requires corrective lenses to produce clear retinal images asti...

emmetropia - ANSWER normal refraction presbyopia - ANSWER natural elasticity of the lens is lost w/ age. Lens is unable to assume more spherical shape for viewing near objects. requires a convex lens hyperopia - ANSWER farsightedness, eyeball is too short, light rays converge toward a point behind the retina. requires a convex lens myopia - ANSWER nearsightedness, eyeball is too long, light rays hit in the front of the retina. requires a concave lens. astigmatism - ANSWER irregular c...
