Frequently Asked Questions

Unlike standard photochromic lenses that rely on ambient UV light exposure and take up to several minutes to darken or clear, Chamelo utilizes Japanese-engineered liquid crystal electrochromic film technology. An integrated micro-controller supplies a low-voltage electrical signal to realign molecules within the film instantly (under 0.1 seconds).

Key advantages include:

• Instant response speed (<0.1 sec switch time).
• Manual control via slider, tap sensor, or dynamic automated tint sensors.
• Full functionality inside vehicles (behind UV-blocking glass) and indoors.
• Consistent UV protection regardless of current tint transmission state.

VLT ranges vary based on the frame design and intended environmental use case:

• Sport Series (Music Shield Gen 2, Shield Black): 63% VLT (light tint for dusk/overcast) down to 17% VLT (dark tint for direct sunlight).
• Lifestyle Series (Zurix): 50% VLT down to 10% VLT.
• Dusk Classic Series: 38% VLT down to 4% VLT for intense sunlight environments.
• Prismatic™ Series: 65% VLT down to 20% VLT with 4 selectable hue modes (Violet, Blue, Ruby, Amber).

All Chamelo lenses block 100% of UVA and UVB rays (UV400 compliance) at every light transmission level.

Yes. Selected frame architectures like Aura Rx support custom single vision, progressive, and reading prescriptions. Our patented mounting bevel allows certified optical laboratories to glaze prescription lenses into our electrochromic chassis. B2B buyers can procure unglazed frame units directly or integrate with our international laboratory fulfillment network.

All performance sport models—including Music Shield Gen 2, Shield Black, and Golf Shield—are engineered with IPX4 water resistance. This rating protects internal electronics and micro-audio drivers against sweat, splash, and high-intensity rainfall. Frames are not designed for full submersion or swimming.

Yes. Chamelo supplies optical chain stores, sports gear distributors, specialty retailers, and corporate buyers globally. We offer structured wholesale tier pricing, POS marketing collateral, localized packaging support, and technical training for retail staff.

• Optical & UV Standards: ANSI Z80.3 (USA), ISO 12312-1 (Europe), AS/NZS 1067.1 (Australia/New Zealand).
• Electronics & Wireless: FCC (USA), CE (Europe), RoHS, TELEC (Japan).
• Medical Registration: Registered under FDA optical device guidelines.

Compliance documentation and laboratory test certificates are available upon request for commercial buyers.

Standard wholesale orders carry an entry MOQ of 50 units across mixed SKUs. Custom co-branded or licensed custom editions (such as our licensed NBA team series) require higher volume thresholds depending on decoration and packaging specifications.
