lens-making

Lens-making involves shaping transparent materials like glass or plastic to bend light accurately for various uses, such as glasses or cameras. The process includes designing the lens shape using precise calculations, selecting high-quality materials, and then shaping and polishing the surface to exact specifications. Modern techniques may use computer-controlled machines for cutting and grinding, ensuring smooth, accurate surfaces. coatings can also be applied to enhance durability and reduce distortions like glare or reflections. Overall, lens-making combines engineering, materials science, and craftsmanship to produce optical components that focus or disperse light precisely for their intended application.
