Which effect primarily limited image clarity in early Islamic lens making?

💡 Explanation

Images were blurry because spherical aberration focus rays at different points, rather than uniformly. This occurred because lens grinding created spherical surfaces; therefore spherical aberration limited resolution rather than chromatic effects prevalent in later multi-lens designs.
