The moment your lenses keep pace with changing light - and your life.

This is the moment we work for.


Self-tinting lenses with PhotoFusion technology

Comfortable and relaxed indoor and outdoor vision

Do you find switching spectacles inconvenient? One pair of spectacles for all vision needs – that's what many spectacle wearers are looking for! Lenses which automatically adjust to all light conditions dramatically reduce the need to switch spectacles, significantly boosting the wearer's comfort and safety. There has been a vast increase in the performance and speed of self-tinting lenses featuring leading-edge technology, such as PhotoFusion from ZEISS. In the production of self-tinting lenses, millions of photosensitive particles are applied to the lens in the form of a coating. These molecules are able to change their chemical structure when exposed to UV light, with the result that the lens darkens rapidly in sunshine and clears again indoors.

    • UV protection: 100% protection against harmful solar UV radiation is guaranteed – also for clear lenses.
    • Long life and no wear and tear: PhotoFusion lenses will continue to darken and clear for a long time to come – they just keep on performing!

  • Self-tinting lenses: who for?

    24 hours of excellent vision

    It takes just 15 to 30 seconds for lenses with PhotoFusion technology to darken in sunlight. Indoors, the lenses turn completely clear again within 5 to 10 minutes.

    *Average value for 1.67 and 1.6 and for lenses made of polycarbonate. Performance is dependent on the material, temperature and light conditions.

    Who is PhotoFusion suitable for?

  • Technology

    Untiring, photosensitive molecules are at work here!

    Special photosensitive molecules are applied during the coating of the lens in the ZEISS production area. Self-tinting lenses use a chemical reaction that was originally discovered in the 1960s and has been continuously enhanced ever since.

    The principle behind it all is very simple. When sunlight hits the lens, it increases the surface area of these molecules which makes the lenses darken. The stronger the sunlight or UV light, the darker the lens gets. This means that the right tint intensity is always achieved for the level of light. When the level of UV rays drops, the molecules 'fold' again and the lens becomes clearer. The speed at which the molecules act is a good indicator of the quality of self-tinting lenses.
