Freeform Lens Production by KARUSON — Accurate, Comfortable, Reliable

KARUSON, established in 2010, is a global eyewear factory and OEM/ODM supplier with over 15 years of experience in eyewear design and precision manufacturing. Our freeform lens production combines digital surfacing and precision engineering to deliver custom lenses with superior clarity, thinner profiles, and optimized visual zones for every wearer.

Why choose KARUSON freeform lenses?

Freeform lens production creates individually optimized lens surfaces rather than one-size-fits-all curves. The result is better vision across all distances, fewer distortions, and more comfortable wear. Whether you need progressive single-vision prescriptions or specialized sports optics, our freeform technology improves visual performance for optical eyewear, polarized sunglasses, and sports goggles.

Brands in Spain, Europe, and the Americas rely on our consistent delivery and product reliability.

Customization and finishing options

We offer extensive customization for freeform lens production: personalized prescriptions, anti-reflective and hydrophobic coatings, polarized lens options, tinting, and edge finishing for any frame. Our digital surfacing can craft complex progressive corridors and tailored visual zones to match the wearer’s frame choice and lifestyle needs.

Applications and compatibility
