Which visual outcome arose when Alhazen refined lenses?

💡 Explanation

Alhazen's work improved lens grinding techniques, thus minimizing spherical aberration because the lenses focused incoming light more effectively using Snell's Law of Refraction, therefore sharper images were produced, rather than exhibiting the distortions of earlier designs.
