Flattening the base curve randomly on a spherically ground lens will most likely result in which of the following?

When the base curve on a spherically ground lens is flattened randomly, the geometric configuration of the lens changes. This alteration leads to a misalignment of the light rays as they pass through the lens, resulting in optical distortion. Because the lens is designed to focus light to a point, any changes to the curvature can increase spherical aberrations. These aberrations cause light rays that enter the lens at different angles to come into focus at different points, which can lead to a blurred or distorted image.

As a consequence, the quality of vision is adversely affected; thus, the lens is less effective at providing clear vision. The increased aberration that results from this change in curvature is what directly correlates to the decreased clarity of vision experienced by the wearer. It is essential for lenses to maintain appropriate curvature to minimize optical aberrations and ensure that vision remains sharp and clear.
