Fast Photocromic Essilor !

**mauroventura** · 06-30-2005, 09:36 AM

Is there someone who know which kind of photocromic lenses are the Fast Essilor?
It seems special kinds of Transitions lenses ( I mean very fast activation and deactivation , and start of absorption near 30%-40%).

Is it true?

thanks a lot for later answers.

Essilor uses Transitions Next Generation for its plastic lenses and Transitions V for its Poly and 1.67 lenses.

Many other companies uses the same.

Optiboard also has a wealth of Transition info here.

The fast lenses aren't Essilor - they are LifeRx from VisionEase

Really fast to darken but the real difference is in the way they lighten up very fast:)

SignetArmorlite has been touting the rapid darkening and fading of their Kodak Instashades line of photochromic lenses. SV, PALs, 1.56, 1.6 and poly, I believe.
