Answer:
The defect is myopia that causes distant objects to appear blurred, while close objects can be seen clearly.Myopia is corrected by using a concave lens which is placed in front of a myopic eye, moving the image back to the retina and making it clearer.Longsightedness is corrected using a convex (outward facing) lens
