The correct answer is Option C: a concave lens of suitable power. Correction of Myopia (Short-Sightedness) Using Optical Lenses

Step-by-Step Solution & Concepts:
Key Fact: Correction of Myopia (Short-Sightedness) Using Optical Lenses

Given: Eye defect: Myopia (person can see nearby objects clearly but cannot see distant objects distinctly)

Key Facts: Myopia = Short-sightedness $\rightarrow$ Corrected by Concave lens.; Hypermetropia = Long-sightedness $\rightarrow$ Corrected by Convex lens.; Presbyopia = Old-age vision defect $\rightarrow$ Corrected by Bifocal lens.

Steps: Cause of Myopia: In a myopic eye, the image of a distant object is formed in front of the retina rather than on the retina itself, caused by excessive curvature of the cornea or elongation of the eyeball.. Optical Correction Mechanism: A concave lens (diverging lens) of suitable focal length diverges incoming parallel light rays before entering the eye, shifting the focal point back onto the retina.

Answer: Option C is correct — a concave lens of suitable power
