At the beginning of the 20th century, Carl Zeiss revolutionized the calculation and manufacture of eyeglass lenses. This magic moment in 1912 was the brainchild of Moritz von Rohr who calculated the point-focal imaging eyeglass lens, thus laying the foundation for Punktal® eyeglass lenses. It was the first axis-symmetric lens to minimize the blurring that occurs when looking through edge areas of a lens. It is still included in the current product line of Carl Zeiss. With continuous advancements such as new coatings or the incorporation of the wearer’s visual parameters in the Gradal® series, Carl Zeiss Vision is still setting new standards in the field of eyeglass lenses.
