Product Introduction
Optical Convergence: The Engineering of Wide Corridor Digital Freeform Progressives
The Wide Corridor Digital Progressive lens represents a paradigm shift in multifocal optics, specifically engineered to overcome the limitations of traditional progressive designs. For many presbyopes, the primary complaint with standard progressives is the "tunnel vision" effect—a narrow intermediate corridor that forces the wearer to move their head excessively to find the clear focal point. Our Wide Corridor design utilizes sophisticated Digital Freeform surfacing, where the entire prescription is mapped point-by-point on the back surface of the lens. By utilizing complex mathematical algorithms, we are able to push the inevitable peripheral astigmatism further toward the edges of the lens, effectively widening the usable intermediate and near-vision zones by up to 35%. This creates a much more natural visual experience, allowing for comfortable eye-scanning across a computer screen or a book without the constant need for lateral head movement. Furthermore, this design incorporates "Swim Effect" reduction technology, which stabilizes the peripheral image and minimizes the dizzying sensation often felt when walking or navigating stairs. Each lens is customized based on the wearer's specific frame parameters, including the pantoscopic tilt and vertex distance, ensuring that the wide corridor is perfectly aligned with the user's natural visual path. This lens is the ultimate solution for active professionals who require seamless, high-definition vision at all distances with an almost instantaneous adaptation period.

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.

Frequently Asked Questions (FAQ)
- Q: What makes a "Wide Corridor" better?
- A: It allows for more lateral eye movement without losing focus.
- Q: Is it harder to adapt to than regular progressives?
- A: No, it is actually much easier due to lower peripheral distortion.
- Q: Can I use these for driving?
- A: Yes, they provide an excellent, wide far-vision field.
- Q: Are these lenses digitally surfaced?
- A: Yes, they use 100% back-surface Freeform technology.
- Q: Do they work with small frames?
- A: Yes, we offer short-corridor versions for shallow frames.
- Q: Can I add a blue-light filter?
- A: Absolutely, blue-cut monomer is recommended for all-day use.
- Q: Is the prescription more accurate?
- A: Yes, digital surfacing is accurate to ±0.01 diopters.
- Q: Do they look different from regular glasses?
- A: No, they look like standard clear single-vision lenses.
- Q: Why is adaptation faster?
- A: Because the "swim" effect is reduced by the stabilized design.
- Q: Are they available in photochromic?
- A: Yes, they can be made in Gray or Brown transition versions.
