Which outcome was more likely when Medieval Islamic lenses suffered bubbles?

💡 Explanation

Image distortion increased due to light scattering at air-glass interfaces within bubbles, a process known as Tyndall effect. Therefore, image fidelity suffered, particularly for astronomical observations, rather than only affecting the lens's chromatic dispersion or focal length.
