Aspheric lenses

Aspherical lenses have a special shape that is not perfectly symmetrical, which allows them to minimize optical image errors, called aberrations. The most common are spherical aberration, which causes an out-of-focus image because light rays passing through different parts of the lens do not converge to a single point, and chromatic aberration, which creates colored edges around objects due to the different refraction of light of different colors. Due to their unique shape, aspherical lenses eliminate these distortions, allowing for a sharp and clear image.
