Sunglasses Ocean Lens — Saltwater-Resistant Coating

User Scenarios

• Activities with Ocean Exposure: Water sports such as surfing, stand-up paddle (SUP), and beach activities, where it effectively resists the weak alkaline erosion of seawater.
• Outdoor Sports Prone to Mud and Sand: Events like triathlons, cycling, and road running, where lenses are frequently splashed with muddy water, sweat, or dirt.
• Daily Easy Maintenance: Ideal for everyday users looking to minimize eyewear maintenance time, enjoy simple cleaning, and extend the lifespan of their sunglasses.

Principles of Operation

• Seawater Resistance (Chemical & Physical Defense): Seawater is slightly alkaline (pH 8.0 to 8.3) and contains large amounts of salt and impurities. The coating utilizes materials that are highly resistant to acids and alkalis, drastically reducing chemical erosion from seawater and sweat on the inner lens. Additionally, its physical toughness prevents salt and sand from directly scratching the lens.
• Oil & Smudge Resistance (Nanotechnology & Lotus Effect): Employing vacuum-deposition "nano-engineering technology," an ultra-fine protective film is applied to the outermost layer of the lens. This film fills in the microscopic imperfections on the lens surface, making it exceptionally smooth. Similar to the natural lotus effect, dust, grease, and water droplets cannot securely adhere due to the lack of anchor points, giving the lens excellent self-cleaning properties.

What is TR90?

TR90 (also known as "Plastic Titanium") is a high-tech thermoplastic material originally developed by the Swiss company EMS. It is highly celebrated in the eyewear industry for its revolutionary combination of lightness, flexibility, and extreme durability.

TR90 frames are ideal for everyone, but particularly recommended for:

• Children: Due to its shatterproof, safe, and flexible nature.
• Athletes / Outdoor Enthusiasts: It provides reliable eye protection and stays securely in place during vigorous movement without hindering performance.
• Daily Long-Term Wearers: Anyone seeking to minimize eyewear fatigue during long office hours or daily commutes.

Photochromic (Light-Adapting) Lenses

User Scenarios

• All-Weather Alpine & Snow Sports: Optimized extensively for skiing and snowboarding. Because snow has a massive UV reflectivity rate of up to 95%, these lenses are designed to activate and protect even on overcast or flat-light days when invisible UV rays still penetrate the clouds.
• Variable-Light Outdoor Sports: Perfect for transitions from deep indoor/shaded areas to blinding outdoor environments, or long sessions running from dawn to dusk.
• One Lens, All Day: Eliminates the hassle of carrying separate lenses for sunny and cloudy periods.
