Which fundamental effect resulted from Alhazen's improved lens grinding?

💡 Explanation

Alhazen painstakingly shaped lenses, which improved focusing; reducing spherical aberration arose because shaping lenses closer to parabolic paths allowed precise convergence, therefore minimizing blurring. This outcome occurred rather than exacerbating it given uneven thicknesses.
