Question

Assess your ability to differentiate between myopia and hyperopia by classifying the following characteristics as appropriate. Defect occurs because the eyeball is too short, or the lens refracts too weakly Also called nearsightedness Also called farsightedness Images of faraway objects focus on a point Correction includes concave lensto causeImages of nearby objects focus on a point in front of the retina light rays to spread apart or diverge behind the retina Distant objects are seen if the accommodation reflex is activated to increase lens curvature Correction includes convex lens to cause light rays to meet or converge Defect occurs because the eyeball is too long or the lens refracts too strongly Hyperopia Myopia

Explanation / Answer

Also called nearsightedness - myopia

Defect occurs because the eyeball is too short, or the lens refract too weakly - hyperopia

Also called farsightedness - hyperopia

Images of faraway objects focus on a point infront of the retina - myopia

Correction includes using concave lens to cause light rays to spread apart or diverge - myopia

Images of nearby objects focus on a point behind the retina - hyperopia

Distant objects are seen if the accomodation reflex is activated to increase lens curvature - myopia

Correction includes using convex lens to cause light rays to meet or converge - hyperopia

Defect occrus if the eyeball is too long or the lens refract too strongly - myopia
