Question

Answer

Myopia means short-sightedness, in this, a person has a clear vision when looking at objects close to them, but distant objects will appear blurred, to correct it easily concave lens is placed in front of a myopic eye, moving the image back to the retina and clarifying the image. This makes option B correct !!

Answer

If a person is suffering from myopia then the light rays will converge before the retina and not on it. So he should use a lens which diverges the rays before entering the eye so that the image is formed exactly on retina. Therefore he must use concave lens which is diverging lens.

Answer

Concave lens

Answer

Concave lens is used to correct myopia and the convex lens is used to correct hypermetropia.

Answer

The lens which is used to correct myopia is Concave lens.
(option B )

Answer

Introduction:
Correcting myopia, also known as shortsightedness, involves the use of specific lenses to improve distance vision. These lenses work by altering the way light enters the eye, focusing it properly onto the retina. The lens commonly used for this purpose is a concave lens.

Explanation:
A concave lens is a diverging lens that is thinner in the middle and thicker at the edges. It causes light rays to spread out or diverge after passing through it. This divergence counteracts the excessive focusing power of the myopic eye, allowing the light to properly focus on the retina.

How a concave lens corrects myopia:
When a person has myopia, the light rays entering the eye converge in front of the retina, resulting in a blurred image for distant objects. By placing a concave lens in front of the myopic eye, the lens causes the light rays to diverge before entering the eye. This divergence compensates for the excessive convergence of the myopic eye, allowing the light to focus properly on the retina.

Key points:
- Myopia, or shortsightedness, is a condition where distant objects appear blurry.
- A concave lens is used to correct myopia.
- A concave lens is a diverging lens that causes light rays to spread out or diverge.
- By using a concave lens, the excessive convergence of the myopic eye is compensated, allowing the light to focus properly on the retina.
- The concave lens helps to move the virtual image formed by the myopic eye to the retina, resulting in clearer distance vision.

Conclusion:
In conclusion, the correct lens used to correct myopia or shortsightedness is a concave lens. This lens helps to diverge light rays entering the eye, compensating for the excessive convergence of the myopic eye and allowing the light to focus properly on the retina. By using a concave lens, distant objects appear clearer and more focused for individuals with myopia.
