Which effect occurred due to Ibn al-Haytham's improved lens grinding techniques used for early reading stones?

💡 Explanation

When grinding techniques improved, less surface asphericity resulted because better control over the lens shape diminished the blurring caused by light rays not converging at a single focal point. Therefore, diminished spherical aberration artifacts resulted, rather than other improvements, as manufacturing influenced this effect primarily.
