Product Introduction
Unbeatable Protection: The 1.59 Polycarbonate Advantage
When safety and durability are non-negotiable, the 1.59 Polycarbonate lens is the ultimate choice. Originally developed for aerospace applications (helmet visors) and bulletproof windows, this material is virtually indestructible under normal optical use. Polycarbonate is a thermoplastic material that is injection-molded rather than cast, resulting in a lens that is 10 times more impact-resistant than standard plastic or glass. This makes it the mandatory standard for children’s eyewear, sports goggles, and industrial safety glasses. Beyond its incredible strength, the 1.59 index is surprisingly thin and is the lightest material in the optical industry (with a specific gravity of 1.20). Every 1.59 lens we produce comes with inherent 100% UV400 protection, blocking all harmful solar rays without the need for additional coatings. To counter the natural softness of the material, we apply a specialized, cross-linked hard coat that provides superior scratch resistance. For athletes, active students, or anyone in a high-risk environment, the 1.59 Polycarbonate lens provides the peace of mind that their eyes are protected by a ballistic-grade barrier that remains crystal clear and comfortable all day long.

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: Can polycarbonate lenses break?
- A: They are extremely resistant and will crack rather than shatter under extreme force.
- Q: Are they good for rimless frames?
- A: Yes, they are highly recommended for rimless and semi-rimless designs.
- Q: Do they scratch more than CR-39?
- A: The material is softer, so we include a reinforced hard coat to protect them.
- Q: Are they heavy?
- A: No, they are the lightest lenses available on the market.
- Q: Do they have built-in UV protection?
- A: Yes, 100% UV400 protection is a natural property of polycarbonate.
- Q: Are they as clear as 1.50?
- A: They have a lower Abbe value (30), but modern coatings minimize any visual issues.
- Q: Can I use them for sports?
- A: Yes, they are the gold standard for sports and high-activity eyewear.
- Q: How are they manufactured?
- A: Through a high-precision injection molding process.
- Q: Is Blue-Cut available?
- A: Yes, we offer Blue-Cut polycarbonate for digital safety.
- Q: Are they suitable for high-power prescriptions?
- A: They are thin enough for moderate powers, but 1.67+ is better for very high powers.
