Rare Earths

By integrating Rare Earths and selected Lanthanides into the glass melt, Barberini® creates lenses with enhanced visual performance and distinctive colour definition.

These advanced mineral oxides selectively filter light frequencies to intensify contrast and enrich the perception of colours such as green, red, blue, and yellow.

Combined with sophisticated treatments and coatings, this technology delivers a brighter, sharper, and more natural visual experience, elevating comfort, clarity, and protection in every light condition.
