Which type of lens is used to correct near sightedness ?

Correct option is B

The correct answer is (B) Concave lens

1. Nearsightedness (myopia) causes difficulty in seeing distant objects clearly.

2. Concave lenses are thinner at the center and thicker at the edges, which helps in diverging light.

3. The lens helps to adjust the focal point to the retina, improving vision.

4. Concave lenses are commonly used in eyeglasses and contact lenses for myopia.

5. The correction process allows the person to see distant objects clearly, as the light is appropriately refracted.

6. Concave lenses are typically prescribed after an eye exam that diagnoses the severity of myopia.

•  Plano-convex lens – This lens is used in some optical instruments to focus light but does not correct nearsightedness.

•  Convex lens – A convex lens is used to correct farsightedness (hyperopia), not nearsightedness.

•  Plano-concave lens – This lens is used for specific optical applications but is not commonly used to correct nearsightedness.
