Lens Manufacturing Technology: From Blank to Finished Prescription Lens

Lens Manufacturing Technology: From Blank to Finished Prescription Lens

Short Answer: Ophthalmic lens manufacturing transforms a semi-finished lens blank into a prescription lens through four core stages: surfacing (or freeform generation), polishing, coating, and edging. Material choice (CR-39, polycarbonate, Trivex, or high-index plastic) determines the optical and physical properties of the final lens. Coating technologies (AR, hard coat, hydrophobic, oleophobic, and blue light filter) are applied in layers to improve performance and durability.
