Which refinement applied to lenses improved image quality within medieval Islamic astrolabes?

💡 Explanation

Spherical aberration resulted in blurred images, so during the Islamic Golden Age, advances in lens grinding techniques allowed scientists to minimize this defect through aspheric lens shaping, leading to sharper image construction from focused light rays. Therefore, aberration correction helps image construction, rather than achromatic lenses, or segmented and reflective applications which are either beyond the period or not used for that application.
