(B) Near-sightedness,or myopia,is a common refractive error of the eye. Myopia occurs when the eyeball is too long relative to the focusing power of the cornea and the lens of the eye. This causes light rays to focus at a point in front of the retina,rather than directly on its surface. To correct this,a diverging lens is required to shift the focal point back onto the retina. $A$ concave lens is a diverging lens,which is why it is used to treat myopia.
