The Carl Zeiss optical lens is attributed to German businessman and optometrist Carl Zeiss. The name Carl Zeiss is recognised globally for its high-quality optical instruments, industrial measurement tools, and medical equipment. He founded the ZEISS workshop in Jena, Germany, in 1846 to produce microscopes and other optical tools. Working together for a very long time is Zeiss and Nokia. Several Nokia cell phones are fitted with Carl Zeiss Optics. This optics feature does not, however, stop Nokia's fall.
