Sports sunglasses manufacturers

When sourcing sports sunglasses, prioritize Polycarbonate or Trivex lenses because they are impact-resistant and shatterproof, which is essential for athlete safety. For outdoor sports with high glare (like cycling or water sports), ensure the lenses are Polarized to reduce eye strain. Additionally, look for UV400 protection to block 100% of UVA and UVB rays, and consider Photochromic lenses that automatically adjust to changing light conditions.

The frames should be made of TR90 (Thermoplastic Polyamide), a material known for being lightweight, flexible, and extremely durable. To ensure the glasses stay in place during intense activity, verify that the design includes hydrophilic rubber nose pads and temple tips that increase grip as the athlete sweats. A wraparound design is also critical to provide a wide field of vision and protection from wind and debris.

For the US market, products must comply with ANSI Z87.1 for high-impact resistance and FDA 21 CFR 801.410 (the drop ball test). For the European Union, ensure the sunglasses carry the CE Mark and meet the EN ISO 12312-1 standard. If you are sourcing for children's sports, CPSIA compliance regarding lead and phthalate content is mandatory.

Request a Hinge Durability Test report to ensure the frames can withstand repeated opening and closing. You should also ask for Anti-scratch coating validation and Salt spray testing results, especially if the products will be used in coastal or marine environments. Conduct a visual clarity inspection to ensure there is no distortion in the peripheral vision areas of the lens.

The primary risks include Intellectual Property (IP) infringement if the design mimics patented brand shapes, and non-compliance with medical device regulations (as sunglasses are often classified as Class I medical devices). To mitigate this, use Made-in-China.com's 'Audited Supplier' reports to verify the manufacturer's legal standing and production capabilities before placing a bulk order.

Negotiate based on Total Landed Cost. While a low unit price is attractive, factor in customization costs for logos (OEM) and packaging. Many professional suppliers on Made-in-China.com offer tiered pricing; aim for a 15-20% discount on volumes exceeding 1,000 units. If you are a startup, negotiate a lower MOQ for a trial shipment by agreeing to use the supplier's 'in-stock' frame colors.

Always use Secure Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. For shipping, choose Air Freight for high-value, low-volume samples to speed up the approval process, but utilize Sea Freight (LCL or FCL) for bulk orders to maintain healthy profit margins. Ensure the supplier uses protective inner-box dividers to prevent lens scratching during transit.
