High Index Polarized Lenses
This urethane based lens has the unique features. The High Index Polarized Lens has better optical property compare to CR39 or Polycarbonate lenses. Suitable for high end products for lens labs.
We have 1.60,1.67 and 1.74 index lens for this high-end collection. The raw materials are all MR monomers which are most popular high index monomers in the market.
Please contact us for more details.
The material index enables you to provide thinner and lighter lenses to your patients.
This polyurethane based material lens has much more clarity compare to the Polycarbonate lens which is popular in North America.
Crack and Craze Resistance:
Also as this material is softer than polycarbonate, you do not need to worry about cracking or crazing during the process of drilling. Of course it has still enough impact resistance to pass ANSI standard.
Have you experienced delamination problem with CR39 polarized lens?
Polyurethane has strong adhesibility as its material feature. So you do not have to worry about delamination at all.
