China Wholesale Prescription Sunglasses Suppliers & Exporters

Our factory utilizes two primary integration methods based on the target retail model. Method 1 involves custom optical clip-in inserts mounted directly behind the electrochromic lens stack, allowing wearers to easily swap corrective powers. Method 2 utilizes precision CNC optical edging to mount prescription single-vision or progressive lenses into customized frame rim grooves adjacent to the electrochromic liquid crystal layer, ensuring constant corrective power while tint changes dynamically.

Standard ready-to-ship wholesale stock orders start at low MOQs (50–100 units). For custom OEM branding (custom frame colorways, branded packaging, laser-engraved logos, and custom firmware bluetooth pairing names), MOQs typically start at 500 units per model. Full ODM custom frame design tooling starts at 1,000 to 2,000 units depending on plastic injection mold complexity.

Depending on the chosen electrochromic film platform, our frames cover VLT transitions from as high as 65% (ideal for indoor or low-light sport environments) down to 4% (extreme sunlight/glare conditions). The transition is controlled directly via a capacitive touch slider on the temple arm or an automated light-sensor micro-controller, taking less than 1 second to shift.

Electrochromic tint technology is exceptionally power-efficient because electrical current is drawn almost exclusively during state changes. Pure tint-control frames can run for several weeks on a single charge. Combined audio-tint platforms feature dual rechargeable lithium-polymer batteries (80mAh to 120mAh total capacity), delivering up to 6–8 hours of continuous audio playback and instant magnetic fast-charging (80% charge in ~80 minutes).
