What does CNC stand for in the context of lenses and contact lens manufacturing?

In the context of lenses and contact lens manufacturing, CNC stands for Computer Numerical Control. This term refers to a manufacturing process in which computer software is used to control machine tools. In the production of lenses, CNC technology allows for high precision and intricate designs to be achieved in the shaping and finishing of contact lenses. This automated approach not only increases accuracy but also enhances efficiency in the manufacturing process, allowing for consistent quality across large quantities of lenses.

The application of CNC technology in the optics field is pivotal, as it enables manufacturers to craft lenses that meet specific vision correction specifications while ensuring that the production runs smoothly and effectively. The use of computer technology streamlines the manufacturing process, reduces human error, and can lead to higher customization options for patients, ensuring that contact lenses can be tailored to individual needs.
