Question

assess your ability to differentiate between myopia and hyperopia by classifying the following descriptions. connection includes concave lens to cause light rays to spread apart or diverge. images of far - away objects focus on a point in front of the retina. connection includes convex lens to cause light rays to meet or converge. also called nearsightedness. defect occurs because the eyeball is too long or the lens refracts too strongly. also called farsightedness. defect occurs because the eyeball is too short, or the lens refracts too weakly. images of nearby objects focus on a point behind the retina. distant objects are seen if the accommodation reflex is activated to increase lens curvature. hyperopia myopia

Explanation:

Myopia (nearsightedness) occurs when the eyeball is too long or the lens refracts too strongly, causing images of distant objects to focus in front of the retina. It is corrected with a concave lens to diverge light rays. Hyperopia (farsightedness) happens when the eyeball is too short or the lens refracts too weakly, making images of nearby objects focus behind the retina. It is corrected with a convex lens to converge light rays.

Answer:

Hyperopia:

• Defect occurs because the eyeball is too short, or the lens refracts too weakly
• Images of nearby objects focus on a point behind the retina
• Connection includes convex lens to cause light rays to meet or converge
• Also called farsightedness
• Distant objects are seen if the accommodation reflex is activated to increase lens curvature

Myopia:

• Defect occurs because the eyeball is too long or the lens refracts too strongly
• Images of far - away objects focus on a point in front of the retina
• Connection includes concave lens to cause light rays to spread apart or diverge
• Also called nearsightedness
