Question

A person cannot see the objects placed between near point and the point of least distance of distinct vision. His defect of vision can be corrected by using

• A. bi-concave lens
• B. bi-convex lens
• C. bi-focal lens
• D. concavo-convex lens

Answer 1

The Correct Option is B

The defect described here is myopia (nearsightedness), where a person cannot see objects placed beyond a certain distance (the far point) clearly, and typically objects placed between the near point and the point of least distance of distinct vision appear blurry.

Correction:

The defect of myopia can be corrected using a concave lens (also called a diverging lens). This lens helps diverge the light rays before they enter the eye, shifting the focal point to the retina.

Correct Answer:

The defect can be corrected by using a bi-concave lens.

So, the correct option is:

bi-concave lens
