Which visual distortion arises because imperfections in ancient lens grinding?

💡 Explanation

Spherical aberration occurs because curved lens surfaces incorrectly focus light rays; lens makers aimed for uniform spherical surfaces. Therefore, sharp imaging degrades rather than colors separating (chromatic), or wave interference or polirization playing a role.
