This allows you to verify the coating quality, lens clarity, and progressive corridor design firsthand. Danyang's optical manufacturing cluster means suppliers in the area often have established logistics channels for international shipping.
Progressive lenses require precise fitting, so confirm the exact corridor length, fitting height, and available addition powers with Changxing Optical to ensure the lenses meet your market's requirements. Ask for their current product catalogue and specification sheets. The supplier offers both finished and semi-finished lens options, which may be relevant if you have your own surfacing lab.
