To minimize the spherical aberration, parobolic mirrors can be used mainly in astronomical telescopes to enhance image quality. The answer is not too complicated: parabolic mirrors work better to produce nice, tight beams of light. At focus of the mirror. When an object is placed at its focus it produces its respective image at infinity (see figure). When you spin a parabola around its axis to make a curved surface, you get the surface with the shape that's used for the reflector in car headlights, flashlights, solar cookers, telescope mirrors,.
