Wide Corridor Digital Freeform Progressive

A digital-age progressive lens with an expanded visual channel for effortless multi-tasking.

Product Introduction

The Evolution of Varifocals: Maximizing the Visual Corridor

Traditional progressive lenses often force users to "hunt" for the sweet spot, leading to neck strain and a claustrophobic visual experience. Our Wide Corridor Digital Freeform Progressive Lens is engineered to solve this by fundamentally redesigning the intermediate and near zones. Using state-of-the-art back-surface digital surfacing, we expand the usable "corridor"—the area of the lens used for computer screens and smartphones—by up to 35% compared to standard designs. This is achieved by moving the unwanted peripheral astigmatism further toward the edges of the lens, creating a much broader channel of clear vision. The "Digital Freeform" process means the lens is not made from a static mold but is carved point-by-point based on the wearer's specific prescription, pupillary distance, and frame measurements. This personalization ensures that the focal zones are perfectly aligned with the wearer’s natural eye movements. Whether you are shifting your gaze from a driving task to a dashboard or from a physical book to a tablet, the transition is seamless and free of the "swim effect." This design is particularly favored by modern professionals who spend significant time on digital devices but require the versatility of a single pair of glasses for all-day use. Crafted from high-clarity optical resins, these lenses provide a natural, wide-angle view of the world, making them the gold standard for easy-adaptation progressive eyewear.

Technological Highlights: Premium Monomers and Coating Integrity

  • High-Purity Monomer Selection: We exclusively use high-performance monomers (e.g., MR-series) to achieve superior tensile strength and optical purity, resulting in excellent clarity and minimal risk of yellowing over time.
  • Precision Liquid Casting Process: The lenses are produced via a controlled liquid casting method that ensures uniform material density and refractive index consistency across the entire blank, which is critical for accurate therapeutic power zones.
  • Advanced Vacuum Multi-Coating (SHMC): Coatings are applied in a high-vacuum chamber, using multiple layers of metallic oxides to create a durable, anti-reflective stack. This process guarantees maximum light transmission and minimal glare.
  • Thermal Curing Optimization: A slow and precise thermal curing cycle is employed to maximize the material’s resistance to internal stress, ensuring the finished lens remains stable and optically perfect under varying temperature conditions.
  • Integrated Peripheral Defocus Geometry: The therapeutic design is engineered into the mold itself for cast lenses, or applied via digital surfacing for semi-finished blanks, guaranteeing the accuracy and consistency of the myopia control zone geometry.
