Myopia is also known as nearsightedness. A person who is suffering from this eye defect cannot see the distant objects clearly. The normal vision of the eye is 25 cm. In this eye ball is longer than usual and light rays converge in front of the retina which forms the blurred image. The image is formed in front of the retina to the person who is having this defect. So, the person is advised or recommended to use a concave lens of the correct power. So, the image will form on the retina. Thus, this eye defect can be rectified.

Hypermetropia is the eye defect also called nearsightedness. In this eyeball is shorter than the normal. When the light rays strike on the retina before convergence it forms a blurred image. A person who is having this defect can see the distant objects clearly but cannot see the near objects very clearly. This is because light rays from the object focussed at the point behind the retina. This condition can be corrected by using an appropriate convex lens.
