How to design the contact lens with CAXCAD？
Contact lenses are medical devices used to correct vision, placed directly on the surface of the eye or cornea unlike traditional eyeglasses. They are typically made of soft, breathable materials for comfort and adaptability. Contact lenses can correct vision problems such as nearsightedness, farsightedness, and astigmatism, providing a more natural appearance without obscuring facial features.

Successful cases of CAXCAD in glass optimizationIn October 2022, CAXCAD's optical design software successfully utilized its material optimization function to complete the design of a medical confocal microscope tube lens. The optimized material used CDGM glass material from China's Chengdu Glass CDGM, optimizing the chromatic aberration of the lens from 400 to 2000nm to the diffraction limit. In January 2023, the lens product designed by CAXCAD was delivered to Beijing Institute of Technology and passed the testing and acceptance smoothly.

ToleranceCAXCAD's tolerance analysis feature, which is sensitive to lens manufacturing, can help users better control dimensional variations during the design process, thereby reducing manufacturing defects and product failure rates. CAXCAD also provides a tolerance instruction set, which allows users to customize the instructions and parameters required during the tolerance analysis process. This feature enables users to conduct tolerance analysis more flexibly to meet different design and manufacturing requirements.
