Comprehensive Guide to Eyewear Lenses: Insights for Optimal Customer Choices

We are a Chinese eyewear manufacturer. Although we do not produce lenses, but a good eyewear manufacturer should know how to help customers choose lenses. This is lens knowledge that general eyewear factories do not know. The following is my brief introduction to the lens. I hope to discuss with you.

AC lens: also called acrylic sheet, with extremely high perspective, lowest cost, brittle material, may have brittle chips when broken, and average stability of optical indicators. Usually used in the cheapest reading glasses lenses or transparent fixed-shaped lenses of optical frames.

PC lens: injection molding process. When the thickness reaches a certain level, it is bulletproof glass, which is strong and impact-resistant, not easy to break, and not expensive; because PC and Acetate are incompatible, PC lens can only be used in injection molding frames, usually used in sports sunglasses and labor protection glasses.

TAC lens: It is a polarizing technology. Unlike the injection molding process of other lenses, it is made by lamination, and the polarizing layer is sandwiched like a sandwich. The price is relatively low, and it is the most cost-effective polarizing function lens among all polarized lenses, but the disadvantage is that the thickness is thin, the light transmittance is poor, and stratification will occur after a long time or soaking in water.Usually used in some economical or small brand sunglasses

CR39 lens: casting process. Lightweight,easy to dye, rich colors, and strong optical properties. It is the preferred choice of some mid-to-high-end sunglasses brands.

Nylon lens: injection molding process. Made of nylon, it has high elasticity and strong impact resistance. It is relatively expensive and is a safety lens. The manufacturing process is relatively environmentally friendly. It is the preferred choice of some mid-to-high-end sunglasses brands.

Glass Lens: high clarity, but heavy and easy to break, high price, few people use it recently.

Except for TAC lens, all the above are non-polarized lenses. If you need to increase the polarization effect, you need to add a polarizing layer during the manufacturing process, which will increase the cost.

We hope this guide helps you better understand the different types of lenses and their applications. For more details, please contact us!
