Lesson 1: Speed.
How much faster do PhotoFusion® high- and mid-index self-tinting lenses react to changing light conditions?
From dark to clear up to 2 times faster* and from clear to dark up to 20% faster* than previous photochromic lenses by ZEISS.
*Average performance for 1.67, 1.6 and polycarbonate lenses. Performance will vary according to material, temperature and light conditions.
** This is a simulation and does not reflect the actual time it would take for the lenses to react in varying light conditions.
Lesson 2: Innovative Technology.
How do the molecules in PhotoFusion® work?
Photo-active molecules for high- and mid-index self-tinting lenses respond more efficiently to light energy. This is why they react so fast, opening up like microscopic umbrellas when hit by solar UV rays and closing up again when the solar UV rays are less intense.next Lesson
Lesson 3: UV protection.
How well does PhotoFusion® protect against solar UV rays?
PhotoFusion® provides 100% solar protection.
Under all light conditions.
Lesson 4: Aesthetics.
Does PhotoFusion® turn dark and clear in a homogenous way?
Yes. With PhotoFusion® the tinting process is even and homogenous.next Lesson
Lesson 5: Very dark and very clear.
How dark are the PhotoFusion® high- and mid-index lenses in the dark state and how clear in the clear state?
The PhotoFusion® high- and mid-index lenses turn very dark when the solar
UV radiation is strong, achieving maximum clarity again when indoors.
- Clear state: 92 % T*
- Dark state: 11 % T*
*Average performance for 1.67, 1.6 and polycarbonate lenses. Performance will vary according to material, temperature and light conditions.next Lesson
Lesson 6: Durability.
Do PhotoFusion® high- and mid-index lenses retain their performance?
Yes. PhotoFusion® high- and mid-index lenses retain their strong self-tinting performance for a long time.next Lesson
Lesson 7: Wearer Trial.
How many people think that PhotoFusion® high- and mid-index lenses are better or equal than their old photochromic lenses?
97% stated that PhotoFusion® high- and mid-index lenses were better or equal.
