印度采购需求：眼镜片、透明镜片、防蓝光镜片、变色镜片、处方镜片、半成品镜片

I'm reaching out to inquire about the availability of stock lenses. I'm particularly interested in understanding the range of options you have, including various specifications and any potential discounts for bulk purchases. Additionally, it would be great to know the lead times for delivery and if there are any minimum order requirements. Please share any catalogs or product sheets you have, as I'm keen to explore what you offer. Looking forward to your prompt response!
