ZEISS PhotoFusion

The self-tinting lenses that react fast to changing light.

PhotoFusion was created by ZEISS experts to meet consumer expectations on self-tinting lenses that darken and clear again faster*. The introduction of PhotoFusion in 2011 has triggered a revival in the self-tinting market for these kinds of lenses.

    A state-of-the-art technology for strong performance

    Fast dark. Fast clear.

    PhotoFusion lenses adapt quickly to changing light conditions. The high- and mid-index lenses react up to 2 times faster* from dark to clear and up to 20% faster* from clear to dark than previous photochromic lenses by ZEISS.

    • Lenses darken to 15 %T** in 15–30 seconds*
    • Lenses fade back to 70 % T** in 5–10 minutes*

    Comfortable Vision.

    Indoors the PhotoFusion lenses are very clear whereas outside they turn very dark in the sunlight.

    • Clear state: 92% T**
    • dark state: 11% T**

    T = transmission based on AR coated lenses.

    PhotoFusion – a technical innovation

    The secret behind PhotoFusion technology is patented photo-active molecules that respond more efficiently to light energy, darkening up to 20 % faster* than existing photochromic lenses by ZEISS and fading up to 2x faster*. By combining these molecules with lenses by ZEISS, it has been possible to design a new generation of powerful self-tinting lenses: ZEISS PhotoFusion.

    A new level in wearing comfort
    PhotoFusion lenses by ZEISS incorporate the most important features customers expect from self-tinting lenses. They represent another step forward in wearing convenience and comfort while ensuring that wearers can trust the high quality of a ZEISS product at the same time.

    UV radiation & molecules
    Self-tinting lenses contain molecules that react to UV rays. When hit by UV rays, these molecules are unleashed, thus darkening the lens – the more intensive the UV rays, the darker the lenses. Self-tinting lenses therefore adjust automatically to changing light conditions. And of course, whether the lenses are clear or dark, PhotoFusion always provides 100 % solar UV protection.
