I'm looking for a quote on progressive photochromic lenses designed for myopia control. Specifically, I'm interested in lenses with a blue light protection feature, crafted from polycarbonate material. These should be single vision lenses that offer superior visual comfort and clarity. Please provide details on the options available, along with pricing and any minimum order quantities. Additionally, I would appreciate information on lead times and potential bulk discounts if I decide to order larger quantities. If you have any recommendations or additional features that could enhance these lenses, please share that as well. I'm eager to explore what you can offer and how we can proceed with an order.
