In optics, {{w|spherical aberration }} is an image imperfection that occurs due to the increased refraction of light rays that occurs when rays strike a spherical lens near its edge, in comparison with those that strike nearer the center. The origin lies within the fact, that reflection/ refraction on a spherical surface is not perfectly focused on a single point, in contrast to paraboloid reflective surfaces, that have a single focus point. From the perspective of a viewer, this causes the image to appear blurry. | In optics, {{w|spherical aberration }} is an image imperfection that occurs due to the increased refraction of light rays that occurs when rays strike a spherical lens near its edge, in comparison with those that strike nearer the center.
