How does spherical aberration affect your vision?

Spherical aberration occurs when light rays entering a lens or cornea at different distances from the optical axis focus at varying points, leading to a blurred image. This can cause difficulty in seeing fine details, particularly in low light conditions. In the human eye, it may result in a loss of sharpness and clarity, affecting overall visual quality. Additionally, it can contribute to halos or glare around lights, particularly at night.
