What does an optical lens manufacturer supply?

Can ShenHai Optical produce custom prescription lenses?
Yes. Send lens type, sphere, cylinder, axis, addition, diameter, design, coating, volume and destination for confirmation.
How should a buyer compare 1.56, 1.60, 1.67 and 1.71 lenses?
1.56 is a value-oriented everyday platform, 1.60 is a balanced aspheric option, 1.67 is a thinner high-index option, and 1.71 is a premium thin-lens option. Prescription, frame, market position and target price determine the best match.

Polycarbonate is commonly selected for lightweight and impact-oriented applications. Confirm the exact application and compliance requirement in the RFQ.
Can you supply anti-reflective and blue-light lenses?
Available treatments depend on the lens family. HMC, AR, hard coat, UV, anti-scratch, anti-glare and selected blue-light options can be discussed against the product specification.
Can you supply photochromic or tinted prescription lenses?
Selected photochromic options are available across relevant families, and the 1.56 tinted sunglass program supports finished or semi-finished discussion. Confirm color, power range, diameter and coating.

OEM and private-label requirements can be discussed for product specifications, labeling, envelopes, protective boxes and other packing details.
What should be included in an optical lens RFQ?
