Which outcome occurred when early lens grinders polished uneven surfaces?

💡 Explanation

Spherical aberration impaired early lenses because imprecise curvatures caused light rays to converge imperfectly through refraction, thereby blurring images rather than forming sharp focal points like a parabolic mirror would.
