Concept:The diagram shows myopia, or nearsightedness, in which distant objects appear blurry.
Explanation:In a myopic eye, light rays from distant objects are focused in front of the retina instead of on it.
This happens because the eyeball is too long or the eye lens is too strong.
To correct this, a concave lens is used.
A concave lens diverges the incoming light rays slightly before they enter the eye.
This shifts the image backward so that it forms exactly on the retina, producing a clear image.
Answer:B. concave lens
