Question

For the myopic eye, how is the defect is cured?

Answer 1

Myopia:

1. Nearsightedness is defined as myopia.
2. People diagnosed with this condition can visualize objects present close to them but unable to see objects far away from them.
3. Myopia occurs due to the light rays entering the eyeball through the lens converging before reaching the retina and hence do not focus accurately.
4. The distant objects appear blurry and out of sight because the image is formed before the retina.

Correction of Myopia:

1. Myopia is corrected by using a concave lens before the eye lens.
2. The concave lens diverges the light rays, hence correcting the path of light rays.
3. Due to this, the image is focused precisely back on the retina.

The diagram represents the corrected case of myopia, where light rays arriving from a distant object diverge through the concave lens to meet at the retina, hence focusing on a clear image.
