Product Introduction
Introduction: The Clear Choice for High Prescriptions and Active Lives
The demand for effective myopia management solutions has grown exponentially, especially for patients with higher prescriptions who require durable, thin, and lightweight lenses. Our High Index Polycarbonate Myopia Lenses represent the pinnacle of modern optical engineering, seamlessly combining superior vision correction with unparalleled impact resistance. Polycarbonate, known originally for its use in bulletproof glass and astronaut helmets, provides an exceptional safety profile, making these lenses the ideal choice for children and adults with active lifestyles. Unlike standard plastic lenses, the high index nature of this material allows for significantly thinner lens edges and centers, dramatically improving the aesthetic appeal for high myopic corrections. This blend of thinness, lightness, and toughness ensures wearers can enjoy clear, corrected vision without the burden of thick, heavy lenses, directly addressing the core needs of patient comfort and confidence.
These lenses are manufactured using advanced casting techniques to ensure perfect optical clarity across the entire lens surface. The inherent UV protection of Polycarbonate material blocks nearly 100% of harmful UV rays up to 400nm, providing a built-in layer of eye health defense. Furthermore, we apply premium anti-scratch (HC) and Super Hard Multi-Coating (SHMC) treatments to enhance surface durability and virtually eliminate glare. The high refractive index (e.g., 1.59 or 1.60 options) ensures that even patients with strong refractive errors achieve a sleek, cosmetically pleasing result. We focus on ensuring that the lens design also incorporates necessary power profiles for effective myopia control, often featuring peripheral defocus technology integrated into the lens structure. This technology, combined with the superior material properties, positions this product line as a critical tool for practitioners managing progressive myopia. The final product delivers exceptional optical quality, reduces visual distortion, and stands up to the rigors of daily life, offering both peace of mind and crystal-clear sight. Our commitment to utilizing only the highest grade raw materials and adhering to strict international manufacturing standards ensures every lens meets the precise optical parameters required for effective long-term eye health management.

Technological Highlights: Material Science and Safety
- Advanced Polycarbonate Monomer: Utilizes a high-purity Polycarbonate resin known for its superior thermal stability and optical homogeneity, critical for precise lens casting.
- Integrated UV Absorption: The material composition is engineered to intrinsically absorb 100% of UV-A and UV-B radiation up to 400nm, offering permanent, built-in protection that cannot scratch off.
- Impact Fusion Casting: A specialized casting process ensures the lens is stress-free and optically correct, maximizing the material's inherent impact resistance properties.
- Plasma-Enhanced Coating Deposition: The application of Super Hard Multi-Coating (SHMC) utilizes plasma technology to create an ultra-strong bond with the polycarbonate substrate, preventing peeling and enhancing long-term durability against scratches and abrasion.
- Optimized Aspheric Design: Incorporates advanced optical computations to flatten the lens curve, reducing peripheral distortion and minimizing the "magnification" effect often seen in high-power conventional lenses.
Application: Ideal Usage Scenarios
- High Prescription Wearers: The high index and thin profile are essential for patients with strong myopia corrections seeking aesthetic appeal.
- Active Lifestyles & Sports: Superior impact resistance makes these lenses ideal for athletes, children, and anyone engaged in high-movement activities.
- Safety Eyewear Needs: Excellent durability for use in specific occupational settings requiring enhanced eye protection.
- Long-Term Myopia Management: Prescribed as part of a structured program to help slow the progression of nearsightedness.
- General Daily Use: Offering lightweight comfort and high optical clarity for all-day wear.
Advantage: Why Choose Our Polycarbonate Lenses?
- Extreme Impact Resistance: Provides the highest level of safety and durability, reducing the risk of lens breakage and injury.

Frequently Asked Questions (FAQ)
- Q: What is the primary benefit of Polycarbonate over standard resin material?
- A: The primary benefit is safety. Polycarbonate is inherently impact-resistant, making it up to 10 times more impact-resistant than standard plastic lenses (CR-39). It is also lighter and provides built-in UV protection.
- Q: Are these lenses suitable for children undergoing myopia control treatment?
- A: Yes, they are highly recommended. Their superior impact resistance ensures maximum safety during play and physical activity, while the thin, light profile promotes comfort and compliance for young wearers.
- Q: Does the high index feature affect the quality of the myopia control design?
- A: No. The high index material allows us to create a thinner, flatter lens profile, which is beneficial for the aesthetics, while the sophisticated myopia control design (e.g., peripheral defocus zones) is precisely engineered onto the lens surface regardless of the index.
- Q: What is the recommended cleaning method for these coated lenses?
- A: Use mild soap and lukewarm water, or a specialized lens cleaning spray. Always dry with a clean, soft microfiber cloth. Avoid strong solvents or rough materials that can damage the Super Hard Multi-Coating (SHMC).
- Q: Can the Polycarbonate material be tinted or colored?
- A: Yes, Polycarbonate can be tinted, though it requires specific tinting processes. We offer various tinting and light-absorbing options, including photochromic and polarized treatments, to meet diverse customer requirements.
- Q: What indices do you offer besides 1.59/1.60 for this lens type?
- A: For impact resistance and the best combination of safety and thinness, 1.59/1.60 PC is the standard. For non-safety focus, we offer high index resins like 1.67 and 1.74, which you can find under our other relevant tag pages.
- Q: How does the coating (SHMC) benefit the wearer?
- A: The SHMC (Super Hard Multi-Coating) drastically reduces glare and reflections, enhancing visual acuity, especially in low light or while driving. It also acts as a durable shield against minor scratches and makes the lens surface easier to clean (hydrophobic property).
- Q: What is the typical lead time for a standard order of these lenses?
- A: For finished lenses in standard parameters, the lead time is typically 7-10 working days. For semi-finished blanks or complex custom orders, the time frame will be confirmed upon order details, usually 15-20 days.
- Q: Do these lenses comply with international safety standards?
- A: Absolutely. Our Polycarbonate lenses comply with and often exceed global standards, including CE and FDA registration, confirming their safety and quality for international distribution.
- Q: Can I order these lenses with a Blue Cut feature?
- A: Yes. We can integrate advanced Blue Cut technology into the coating or the material composition, providing protection against harmful high-energy visible (HEV) blue light from digital screens.
