Which limitation was encountered when early Islamic scholars attempted to refine lenses produced using grinding techniques?

💡 Explanation

When Islamic scholars refined lenses via grinding, achieving perfect spherical surfaces proved difficult, leading to beams focusing at different points, forming blurry images from spherical aberration. Therefore, image sharpness was lost, rather than color distortion, scattering, or reduced transmission that would require other material flaws or optical issues.
