Which effect complicated image clarity when Medieval Islamic scholars refined lenses using ground quartz?

💡 Explanation

When Medieval Islamic scholars made lenses by grinding quartz, spherical aberration occurred because achieving perfect spherical curvature was extremely difficult, causing rays at the lens edge to focus differently than those near the center. Therefore, spherical aberration resulted, rather than chromatic, astigmatism, or coma, all of which involve separate optical effects/failures.
