Precision Surface Design for Progressive Lenses.
Elevating visual acuity through advanced computational
surface mapping.
Dual-Platform Precision Lens Manufacturing System
Leveraging advanced COBURN surfacing platforms in our Gongda optical lab, we deliver exceptional surface accuracy for complex optical designs.
With RX freeform equipment imported from COBURN (USA), we precisely design and manufacture each lens according to the wearer's visual parameters—whether high-index, progressive, or special-purpose—reducing distortion and maximizing comfort.
COBURN Precision Surfacing Platform
Optimized for high-throughput, micron-level precision surfacing, ensuring exceptional fidelity for complex progressive profiles.
Gongda Freeform Optimization Platform
Specialized in rapid surface-topography optimization and the tight integration of freeform micro-structures into finished lens designs.
Progressive Lenses
Custom-tailored power transitions
mapped to the wearer's exact
biomechanics. Our freeform process
allows for discrete optimization
between Thin and Wide corridor
options, minimizing peripheral
distortion and maximizing the functional visual field.
Thin Corridor: Rapid power transition for active dynamic focus.Wide Corridor: Expansiveintermediate zones for digital
workspaces.
Micro-Structure Surfacing
Micron-level surface mapping
reproduces complex freeform geometry,
from progressive corridors to
micro-structured zones, directly from
the wearer's prescription and frame
measurements, so the machined surface
matches the calculated design.

Protective Coating
Integration
The integrity of a freeform surface is only as robust as its
final layer. CBC's proprietary hard coating application is
chemically integrated post-machining. This ensures
that the complex micro-structures of freeform
progressive designs remain pristine, offering superior
scratch resistance without altering the calculated
refractive index.
