Lens production involves several key steps to create optical lenses used in glasses, cameras, and other devices. The process begins with selecting raw materials, typically high-quality glass or plastic. These materials are then melted and shaped into rough lens forms, which are later polished to achieve the desired clarity and curvature. After shaping, the lenses undergo various treatments, such as coating for scratch resistance or anti-reflective properties. Quality control checks ensure that each lens meets specific standards before being cut and fitted into frames or devices. This meticulous process ensures that lenses provide clear vision and enhance optical performance.
