History of Eyeglass Lenses

How it all began

At the beginning of the 20th century, Carl Zeiss revolutionized the calculation and manufacture of eyeglass lenses. Moritz von Rohr was the brains behind this technical development in 1912. He calculated point-focal imaging eyeglass lenses, which were marketed under the name PUNKTAL. They were the first axially-symmetric eyeglass lenses to minimize the blurring that occurs when looking through the edge areas of a lens.

It is still an integral part of the current ZEISS product line. Thanks to continuous advancements, such as new coatings and the incorporation of the wearer’s own visual parameters in the Gradal®series, Carl Zeiss Vision is still setting new standards in the area of eyeglass lenses.
