High-Quality Vintage Round Acetate Eyeglasses Frames for Men by China Factory Suppliers - OEM/ODM Available

The 9005 Pilot Double Bridge frames are crafted from eco-conscious materials that meet strict international environmental standards. These materials are free from harmful substances and engineered to reduce environmental impact across their entire lifecycle without compromising durability or style.

The size 50-24-145 represents three key measurements: 50mm is the lens width, 24mm is the bridge width (the gap between the two lenses), and 145mm is the temple arm length. Knowing these dimensions helps you select the ideal fit for your face shape and size.

IP (Ion Plating) gold is an advanced vacuum-deposition plating technology that bonds a highly durable, tarnish-resistant gold layer directly onto the metal frame. It delivers superior scratch resistance and long-lasting color while being more environmentally responsible than conventional electroplating — requiring fewer chemicals and producing a more resilient finish.

The spring hinge mechanism allows the temples to flex outward beyond their standard open position, accommodating a wider range of head sizes without creating uncomfortable pressure points. This self-adjusting design also significantly reduces mechanical stress on the frame joints, extending the overall lifespan of the eyewear.

As shown in the full color catalog above, the 9005 Pilot Double Bridge is offered in a comprehensive range of finishes — from classic understated tones to bold fashion-forward options. Each color is applied using the eco-friendly IP coating process, ensuring both visual appeal and long-lasting quality.

Gently clean the frames with a soft microfiber cloth and an alcohol-free lens cleaner. Avoid prolonged exposure to extreme heat, harsh chemicals, or direct sunlight, all of which can degrade the eco-friendly coatings over time. When not in use, store your frames in a hard-shell case to protect both the finish and the structural integrity of the frame.
