Aesthetic Excellence: 1.67 Ultra-Thin Lens Technology
For individuals with higher prescriptions, the "Coke Bottle" effect of thick lenses can be a source of significant discomfort and self-consciousness. Our 1.67 Ultra-Thin High Index Lenses are designed to solve this aesthetic challenge. By utilizing an advanced MR-10™ or similar high-index resin, these lenses are approximately 35% thinner than standard 1.50 lenses and significantly flatter than mid-index options. The key to our 1.67 series is the standard inclusion of an aspheric design. Unlike traditional spherical lenses, aspheric geometry flattens the curve of the lens, reducing peripheral distortion and the magnification (or minification) of the wearer's eyes. This means that plus-power eyes look less enlarged, and minus-power eyes look less "small," resulting in a much more natural appearance. Despite the extreme thinness, the 1.67 index maintains excellent mechanical properties, making it suitable for all frame types, including nylon-string supra and semi-rimless designs. We apply a premium multi-layer anti-reflective coating to maximize light transmission, which is critical for high-index materials to prevent distracting surface reflections. This is the ideal choice for fashion-forward users with prescriptions exceeding -4.00D who demand a sleek, lightweight, and high-performance visual solution.

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.

FAQ
- Q: Is 1.67 much thinner than 1.61?
- A: Yes, it offers about 10-15% additional thickness reduction.
- Q: Do these lenses look flatter?
- A: Yes, the aspheric design makes them significantly flatter than 1.50 or 1.56.
- Q: Is it good for very high prescriptions?
- A: It is excellent for prescriptions up to -8.00D.
- Q: Can I get them with Blue-Cut?
- A: Yes, Blue-Cut is highly recommended for 1.67 lenses.
- Q: Are they heavy?
- A: No, they are much lighter than standard lenses due to the reduced volume.
- Q: Is the vision clear at the edges?
- A: The aspheric design helps reduce peripheral distortion.
- Q: Can I use them for sunglasses?
- A: Yes, they can be tinted or used with a polarized film.
- Q: Does the lens have UV protection?
- A: Yes, 100% UV400 protection is built-in.
- Q: Is it suitable for rimless?
- A: Yes, though 1.61 is tougher, 1.67 is still very suitable for rimless.
- Q: How do I clean them?
- A: Use a microfiber cloth and standard lens cleaner; the SHMC coating makes it easy.
