Product Features

Aogang CR-39 lenses use the true value of imported CR-39 monomer, the longest history of resin material and the most widely sold lens in middle level country.

  • Compared With Glass Lens


1) It’s inexpensive, since it’s been around for over 70 years. Optically speaking, it has a good, reasonably smooth refractive surface, and very little distortion at the edges of the lens

 

2) The big advantages of CR39 lenses over previous glass lenses were light weight, and better shatter resistance. The lower weight allowed eyeglass makers to experiment with larger size lenses, since CR39 is much lighter in weight.

 

3) Glass lens almost has no UV protection, but CR39 lenses can protect eyes from UV380.

 

  • Compared With Other Index Optical Lens


1. Hardness: The best among other index lenses in hardness and toughness, high impact resistance.

2. Tintable: The most easily tinted than other index lenses.

3. Transmittance: The highest transmittance as compared with other index lenses.

4. ABBE: The highest ABBE value providing the most comfortable visual experience.

5. Consistency: The most reliable and consistent lens product physically and optically.
