3d vision glasses price

When sourcing 3D vision glasses, the most critical factor is synchronization technology. You must confirm whether the glasses use Active Shutter (Bluetooth/RF/IR) or Passive Polarization (Circular/Linear). For professional gaming or high-end home theaters, Active Shutter glasses with a high refresh rate (120Hz-144Hz) are essential to prevent flickering. Ensure the chipset compatibility matches the display brand (e.g., Sony, Samsung, or Epson) to avoid signal mismatch.

The quality of the Liquid Crystal Lens determines the user experience. Look for a Light Transmittance rate of ≥38% to ensure the image isn't too dark. The Contrast Ratio should be at least 1000:1 to provide a clear 3D depth effect. Additionally, verify that the lenses have an Anti-UV coating and a Scratch-resistant layer to extend the product's lifecycle in high-use environments like cinemas.

As electronic optical products, 3D glasses must meet specific regional regulations. For the US market, FCC certification and FDA registration (for optical safety) are mandatory. For the EU, CE marking, RoHS (Restriction of Hazardous Substances), and REACH compliance are required. If the glasses contain lithium batteries, they must have UN38.3 and MSDS (Material Safety Data Sheet) reports for air and sea freight.

Price varies significantly based on the power source. Rechargeable models using Lithium-polymer batteries are more expensive but offer better long-term value; look for a battery life of ≥40 hours per charge. Cheaper models often use CR2032 button cells, which lower the initial purchase price but increase maintenance costs for the end-user. Auto-power off functions are a premium feature that justifies a higher price point by preserving battery health.

Optical products are fragile. You should mandate a Pre-Shipment Inspection (PSI) focusing on the Drop Test (1.2m) and Functionality Test (syncing with a 3D emitter). Use Made-in-China.com's Secured Trading services to ensure payment is only released after the inspection report is verified. Always request reinforced packaging with EPE foam to prevent lens cracking during transit.

In the electronics industry, price is heavily tied to the Internal Component Brand (e.g., the Bluetooth chip). Negotiate by asking for a tiered pricing structure based on volume (e.g., 500, 1000, 5000 units). You can often reduce the unit price by 5-10% if you agree to a longer lead time or by choosing neutral packaging instead of custom-branded boxes.

Shipping items with built-in batteries is classified under Dangerous Goods (DG) regulations. Ensure your supplier provides a Battery Declaration and uses PI967 packaging standards. To save on costs, consider Sea Freight for large volumes, but for samples or small batches, use specialized DG couriers like FedEx or DHL to ensure the goods are not confiscated by customs.

Prioritize Audited Suppliers on Made-in-China.com who have been verified by third-party agencies like SGS or Intertek. Check their Export Experience—suppliers who have exported to your target country for over 5 years are more likely to understand your local compliance and quality expectations. Always use Formal Proforma Invoices that clearly state the Incoterms (e.g., FOB, CIF) and warranty periods.
