PhotoFusion® by ZEISS – the fast-reacting self-tinting lenses:
  • Fast dark. Fast clear. Convenient everyday lenses
  • Comfortable vision indoors and outdoors
  • 100% protection against harmful solar UV rays.


Clear vision indoors. Full solar UV protection outside. ZEISS PhotoFusion lenses, adjust automatically to changing light conditions and they adapt to your lifestyle offering convenience.

The ZEISS high and mid-index self-tinting lenses react up to 2x faster from dark to clear than previous photochromic lenses offered by ZEISS.* The secret is their photo-active molecules which react quickly to changing light.

ZEISS PhotoFusion lenses don‘t just react quickly, they also offer excellent vision under all light conditions. Indoors there are no solar UV rays and therefore the lenses remain clear, no matter  how brightly the sun shines outside. Outside, when it is cloudy the molecules are exposed to some solar UV radiation and in response they grow larger by unfolding themselves – the lens turns semi-dark. In full sunshine the photo-active molecules are hit with the full intensity of solar UV rays and they unfold completely darkening the lens to its maximum.

And what about protection against solar UV rays? Thanks to the premium ZEISS quality you have nothing to worry about in this respect. ZEISS PhotoFusion lenses, offer 100% protection against solar UV rays. Even when the lenses are clear no solar UV rays reach your eyes!
