Question

Which of the following lenses is used to minimize myopia?
A) Convex lenses
B) Concave lens
C) Cylindrical lens
D) Planer lens

Answer 1

Hint
Myopia is also known as the short sighted. A person suffering from myopia, has a clear vision when the object is placed close to them but when that person is not able to see a clearly distant object. Because the image appears very blurred. It all happens because the light rays coming from the long distance get converged or focused in front of the retina. So to correct it we have to use the diverging lens.

Complete step-by-step answer:
Sometimes people face eye defects which cause formation of the blurred image and some the defect is: Myopia and Hypermetropia.
Myopia is also known as Shortsighted. Person suffering from myopia cannot see the distant object because the image formation takes place in front of the retina. Due to this the image appears blurred. So to correct it we have to use the lens which helps to diverge the ray and hence the image formation can take place in the retina and as we all know that concave lens is the diverging lens .It helps to diverge the ray and hence the ray finally converge at the retina.
Correct answer is option (B).

Note
Convex lens is known as the converging lens. Hypermetropia is the eye defect which is also known as far sighted defect. This defect can be corrected using the converging lens or convex lens. People typically become short – sighted as teenagers or in their twenties, with around three in 10 people in the UK being myopic.
