Hint:In human eye, the retina is a very thin layer of tissues where lights rays coming from any object falls and it has nerve cells which have the sensation of sending signals to the brain that light has been received and then the image formation of any object takes place.
Complete answer:
Let us examine the myopia defect in brief. When in some human eyes, the eyeball is somehow longer than normal which is focussing power of the cornea and lens of the human eye then the light rays which comes from an object gets too focused at a point somewhere before the retina rather than falling directly on the surface of retina.
This causes the converging of light and then diverting the light to form a final image which forms a little blurred image, this type of defect is known as myopia. So, when the light rays converge at a point in front of the retina and then diverge to form a blurred image on it, this defect is known as myopia.
Hence, the correct option is A.
Note:Its should be remembered that myopia is also known as Near-sightedness while the defect hypermetropia is known as farsightedness and Astigmatism defect causes the distorted images and the presbyopia defect causes the loss of focussing the image with aging effect.
