NUIIT-Earth™ lenses are the result of the most cutting-edge technological research. They are entirely made of tempered glass and give the eyes the safest shelter in all daylight conditions, even in the most extreme. At the same time, the use of rare earths elements – minerals with special optical properties that enhance the crystal structure – ensures the greatest possible transparency for NUIIT-Earth™ lenses.
All the original NUIIT-Earth™ lenses are identified by 
the engraved on their surface that guarantees their authenticity
NUIIT pays great attention to the subjective characteristics of visual perception, and in order to guarantee the highest levels of well-being, has conceived different types of lenses. Each colour corresponds to a different filtering capacity, which allows the glasses to adapt to the specific needs of the eye wearing them.
