HOYA Free-Form™ surfacing achieves optical results unmatched by any other lens manufacturer. Conventional lens designs are optimized for only one prescription within each base curve. HOYA Free-Form surfacing technology applies both aspheric and atoric curves to the back side of the lens design to optimize all prescriptions within each base curve.

HOYA Free-Form technology:

• Optimizes all prescriptions within each base curve
• Uniquely designs lenses according to the ordered prescription and frame measurement
• Enhances vision acuity
• Provides much wider fields of clear vision at all distances
