We have 1.60 and 1.67 index lens for this high-end collection.
Benefit
- Low weight:
As described above, the material index enables you to provide thinner and lighter lenses to your patients. - Clarity:
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. - Delamination free:
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.
