I. Core Product Characteristics
1. Material and Optical Properties
Material: Made of high-purity polycarbonate (PC), featuring both lightweight design and extremely high impact resistance (in line with international ISO safety standards).
Refractive Index 1.59: Thinner than ordinary resin lenses (1.50), with a reduction of approximately 15% in edge thickness, suitable for moderate to high myopia (300 - 800 degrees) and large-frame glasses.
Transmittance ≥ 92%: Close to the clarity of CR-39 resin lenses, reducing visual distortion.
2. Safety Protection
Bulletproof and impact-resistant: Certified by FDA and CE, capable of withstanding an impact speed of 120 meters per second (10 times that of resin lenses), suitable for sports and children's wear.
100% UV Protection: Built-in UV protection function, no need for additional coating, able to resist light damage to the eyes for a long time.
3. Upgrade of Coating Technology
Surface hardness increased to 6H (ordinary PC glass lenses are 3H), approaching the wear resistance of resin lenses, reducing daily scratches.
Filters out harmful blue light within the range of 415 - 455 nanometers and retains beneficial blue light (480 nanometers), suitable for users of digital devices.
Superhydrophobic and anti-slip coating
Waterproof, oil-resistant, fingerprint-resistant, maintaining clear vision even in rainy or sweaty environments.
4.Purchase Suggestions:
Optometry Adaptation: Suitable for 300 - 800 degrees, recommended products with a refractive index of 800 degrees or above.
Coating Selection:
Daily Use: Hardening + Anti-slip Coating
Digital Dependence: Enhanced Protection + Anti-blue Light Function
Driving Needs: Anti-glare + Anti-fog
Frame Matching: Prefer full-frame or half-frame designs, avoiding frameless designs (the edges of PC lenses tend to appear thicker).
5.Summary: 1.59 PC lenses focus on safety, impact resistance, and high refractive index lightness. By 2025, coating technology will further make up for the lack of wear resistance, becoming the first choice for children, sports enthusiasts, and high myopia patients. Suggest matching functions according to usage scenarios to achieve maximum cost-effectiveness.
Currently, IDEAL OPTICAL have launched a product for children's myopia control: 1.591 Light-Transmitting Astigmatism Control Lens SHMC LRB x6
Its advantages include: lattice diffusion design; inner ring enhancing peripheral astigmatism effect; aspheric design to ensure clear visual areas.
It can better meet the wearing needs of children.
