The Engineering Marvel: Why MR-8 is the Professional Choice
In the world of optical resins, the 1.61 index—specifically using the MR-8™ monomer—is widely considered the most balanced high-index material ever created. While lower indices prioritize cost and higher indices prioritize thinness, MR-8 offers a unique combination of high tensile strength, high Abbe value (optical clarity), and superior heat resistance. This makes it the "Gold Standard" for semi-rimless and rimless (drill-mount) frames. Unlike standard resins that can crack or flake when drilled, the MR-8 material is incredibly tough and flexible, ensuring the integrity of the eyewear even under physical stress. From an optical perspective, its Abbe value of 41 ensures that chromatic aberration remains minimal, providing a clear and comfortable viewing experience that rivals lower-index materials but with a much thinner edge profile. These lenses are roughly 25-30% thinner than 1.50 lenses, making them ideal for prescriptions ranging from -3.00D to -6.00D. Our 1.61 series is processed using high-precision liquid casting, resulting in a lens that is not only aesthetically pleasing but also biologically compatible and highly durable. For patients who lead active professional lives and require a lens that is both light and exceptionally strong, the 1.61 MR-8 is the definitive recommendation.

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.
