Condition that occurs when the image is focused in front of the retina.

• A. Cataract
• B. Astigmatism
• C. Farsightedness (hyperopia)
• D. Nearsightedness (myopia)

Answer: (D)

When the image is focused in front of the retina, the eye is nearsighted (myopia). This happens because distant light is brought to focus before it reaches the retina, usually due to an eyeball that is too long or a cornea that is too curved. The result is clear close-up vision but blurry distant vision. Corrective lenses are typically concave (diverging) to push the focal point back onto the retina, restoring sharp distance vision. In contrast, farsightedness (hyperopia) occurs when the focal point falls behind the retina, making near objects blurry and distant objects relatively clearer with accommodation; it’s corrected with convex lenses. Astigmatism stems from an irregular curvature of the cornea or lens, causing multiple focal points and blurred vision at various distances, not simply a focal point in front of the retina. Cataracts involve clouding of the lens, leading to blurred vision for reasons other than the focal point location.
