NXT® SFSV blanks: Confined tint technology • Following the development of a breakthrough patented “dyes bonding” technology, Intercast can offer the same outstanding properties of lenses in the fixed tint and photochromic SFSV blanks | | | • The dyes and/or photochromic molecules are incorporated in the mass of the SFSV polymer but are confined close to the front surface (less than 0.9mm)
| 
NXT SFSV blanks: Advantages for lab processing | 1. The color is uniform after digital or analogical surfacing and it is not dependent on final prescription and thickness profile
| 2. No longer need to tint lenses pair by pair as colors always match
| 3. Color stability and full UV cut-off over the product life to provide a reliable eye protection in accord with the International Standards | | 4. Ability to strip coatings for process optimization without impacting colors | 5. No color change during hard coating process (no bleaching or fading of the dyes by solvents/chemicals used for cleaning) | | 6. Reduced breakage | | 7. Shorter lab processing time | | 8. Broad compatibility with hard coat and A/R coatings | 9. Visual appeal of the edge finish lens and traditional surface tinted lens | | | | Every Day Use
