Which term describes difficulty seeing distant objects clearly?

• A. Presbyopia
• B. Cataracts
• C. Myopia
• D. Pinna

Answer: (C)

Distant objects appear blurry because the eye focuses light in front of the retina, not directly on it. This is myopia, or nearsightedness, usually caused by an eyeball that’s too long or a overly curved cornea. Because the focal point lies in front of the retina, distant images aren’t sharp, while nearby objects can be seen clearly. Corrective lenses with minus power (concave lenses) diverge light slightly so the focus lands on the retina, improving distance vision. Presbyopia involves trouble focusing on near objects with aging lens changes, cataracts blur vision by clouding the lens at all distances, and the pinna is part of the ear, not the eye.
