Since lenses are inevitably subject to the hazards of everyday use, scratches are the main enemy of uncoated organic lenses or those with a mediocre-quality coating.

The mechanical properties offered by nanocomposite coatings offer an excellent solution.These are sufficiently hard to effectively protect the lenses from scratches while also providing the suppleness required to ensure they do not become detached under extreme conditions of use.

This is the type of coating that BBGR currently uses:
Tonic® offers maximum protection and a sustainable improvement in visual contrast by eliminating the risk of diffraction due to scratches.
