Lab Supply Overview
Lens Blanks Built for RX Surfacing and Regional Fulfillment
Semi-finished lenses are ophthalmic lens blanks that are not yet finished to the final prescription. Optical labs use them as surfacing lens blanks for polishing and coating workflows based on prescription requirements, base curve, add power and local fulfillment needs.
Vena Optics supports semi finished lenses wholesale for labs and distributors that need reliable optical lab lens blanks across common lens designs, indexes, functions and coatings. Optical teams can plan stock by lens design, material, base curve, diameter, coating requirement and target market.
