Correct Answer:
Option B —
Concave Lens
The Principle: Myopia (Short-sightedness)In a "short-sighted" eye (technically known as Myopia), a person can see nearby objects clearly, but distant objects appear blurry. This happens because the light rays entering the eye converge too quickly, forming the image in front of the retina instead of directly on it.
The Cause: This is usually due to the eyeball being too long or the eye's lens having too much curvature (too much converging power).
The Correction: To fix this, we use a Concave Lens (also called a diverging lens). This lens spreads out the light rays before they enter the eye, pushing the focal point further back so that the image lands precisely on the retina.
