Product Introduction
Introduction: The Premium Standard for Digital Life
As digital screens become an inseparable part of our work and personal lives, the eyes are exposed to more High-Energy Visible (HEV) blue light than ever before. Our High Index 1.67 Blue Cut Lens is designed as the ultimate "all-rounder" for the modern prescription wearer. The 1.67 index material is 35% thinner and significantly lighter than standard 1.50 plastic, making it the perfect choice for mid-to-high prescriptions (ranging from -3.00D to -8.00D). By using a high-index monomer, we can achieve a sleek, aesthetic look even in fashionable, thin-rimmed frames, eliminating the "bulky edge" that often plagues high-minus prescriptions.
The "Blue Cut" technology in these lenses is not just a surface coating; it is a "Mass-Absorption" technology. The blue-light-blocking molecules are integrated directly into the lens material itself. This allows the lens to filter out the harmful 415nm-455nm spectrum of blue light—which is linked to digital eye strain and sleep cycle disruption—while allowing the "good" blue-turquoise light to pass through for color perception and mood regulation. Unlike older blue-blocking lenses that had a heavy yellow tint, our 1.67 Blue Cut series utilizes "Residual Color Balancing," resulting in a lens that looks virtually clear on the face while providing maximum protection. Topped off with a premium 16-layer Anti-Reflective (AR) coating, these lenses also eliminate the annoying reflections from overhead lights and computer monitors. This combination of thinness, lightness, and advanced protection makes the 1.67 Blue Cut lens the professional choice for office workers, students, and anyone who demands both style and ocular health in a digital-first world.

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.
Primary Applications
- Mid-to-High Prescriptions: Best for powers between -3.00 and -9.00.

Frequently Asked Questions (FAQ)
- Q: How much thinner is 1.67 compared to 1.50?
- A: It is approximately 35% thinner and much more lightweight.
- Q: Does the lens look yellow?
- A: No, our advanced substrate ensures a clear base without the yellow tint.
- Q: Is the blue protection a coating or in the material?
- A: It is built into the lens material for permanent protection.
- Q: Does it block 100% of UV rays?
- A: Yes, it provides full UV400 protection.
- Q: Can I use these for night driving?
- A: Yes, the premium AR coating reduces glare from headlights.
- Q: Are they good for children?
- A: Yes, especially those with high prescriptions and lots of screen time.
- Q: Do they scratch easily?
- A: No, they feature a high-performance Super-Hydrophobic hard coat.
- Q: What is the benefit for office workers?
- A: It significantly reduces eye fatigue and headaches caused by digital screens.
- Q: Are these aspheric?
- A: Yes, all our 1.67 lenses come with an aspheric design as standard.
- Q: What is the Abbe value?
- A: It has an Abbe value of 32, which is optimal for a high-index lens.
