Does a convex lens help in correcting myopia?

A convex lens is specifically designed to converge light rays, which means it brings them together, and is primarily used to correct hyperopia, or farsightedness, where distant images are focused behind the retina. Myopia, or nearsightedness, occurs when the eye is too long or the cornea has too much curvature, causing light rays to focus in front of the retina.

To correct myopia, a concave lens is used, which diverges light rays, allowing them to focus further back on the retina. Thus, the assertion in the question identifies that a convex lens does not help with myopia, making it clear that the best choice is that a convex lens does not correct this condition at all.
