I'm looking to source various types of progressive lenses for our eyewear line. We are interested in high-quality options that can cater to different prescriptions and customer preferences. Please provide details about the available models, including materials and coatings, as well as any customization options you offer. Additionally, it'd be great to know about your pricing structure, minimum order quantities, and lead times for production. We're keen to establish a partnership with a reliable supplier who can meet our needs consistently while maintaining competitive pricing. Looking forward to your prompt response!
