Answer:
Myopia also known as near sightedness
In nearsightedness (myopia), the point of focus is in front of the retina, making distant objects appear blurry. Nearsightedness (myopia) is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry.
It can be corrected by concave lens.
Myopia is diverging lens.
Hypermetropia is also known as far sightedness
Hypermetropia, sometimes called hyperopia, is the term used to define being longsighted. If you are hypermetropic, the image of a nearby object is formed behind the retina. This means that light is focused too far back in the eye, causing things which are close up to appear blurred.
It can be corrected by convex lens.
Hypermetropia is converging lens.
1) Myopia is the term for nearsightedness. Myopia results when parallel light is focused in front of the retina.
2) This defect is most usually linked with an elongated eyeball.
3) In myopia, a person is not able to see distant objects clearly.
4) Myopia can be corrected by using a concave lens of suitable focal length.
Hypermetropia
1) Hypermetropia due to a short eyeball, causes parallel light to be focused behind the retina
2) People suffering from hyperopia have blurred vision of near objects and a clear vision of farther objects.
3) Hypermetropia is also known as farsightedness.
4) Hypermetropia may be corrected using the convex lens of suitable focal length.
