Waterproof glass lenses are optical lenses treated with multiple layers of nanoscale or polymer coatings on the glass substrate, featuring a hydrophobic effect characterized by "water beading and rolling off upon contact." They also offer multiple functions such as anti-fog, anti-fouling, wear resistance, and scratch resistance.

Core Features

1. High Hydrophobicity: Surface contact angle > 110°, allowing rainwater and sweat to roll off quickly without leaving water stains, ensuring clear vision at all times.

2. Long-Lasting Anti-Fog: Some models utilize a hydrophilic-hydrophobic composite nanofilm, remaining fog-free even after boiling at 80°C for 1 hour and undergoing three cycles of -35°C ? 80°C.

3. High Light Transmission and Low Reflection: Visible light transmittance ≥ 92%, with an anti-reflective coating reducing residual reflection to below 0.5%, eliminating glare during nighttime driving.

4. Scratch and Wear Resistance: Passes a #0000 steel wool friction test of 5,000 cycles without coating detachment; supports over 200 alcohol wipes.

5. Chemical Stability: Resistant to salt spray, acids, and alkalis, ensuring no corrosion during long-term use in coastal or industrial environments.

6. Safe and Eco-Friendly: Lead-free and cadmium-free, compliant with RoHS and REACH regulations. Can be UV or thermally cured with low energy consumption during production.
