Lens treatment and frame features

ANTI-SCRATCH TREATMENT Hardening treatment carried out on the surfaces of the lenses which determines an improvement in terms of resistance against abrasion and therefore, a longer duration in time.

ANTI-SCRATCH TREATMENT PLUS Hardening treatment carried out on the surfaces of the lenses which determines an improvement in terms of resistance against abrasion and therefore, a longer duration in time. In conformity with the optional EN 166 requirements, eyepieces with anti-scratch treatment PLUS satisfy resistance parameters to the damage of surface caused by thin particles (whose minimum provided requirement is a luminance factor lower than 5 cd/(m2∙lx)), thus offering definitely higher performance compared to the standard anti-scratch treatments on the marketplace. COFRA indicates such performances by specifying the maximum luminance factor (expressed in cd/(m2∙lx)) tested by the certification bodies. Therefore, such eyepieces may be marked with the symbol “K”.

ANTI-FOG TREATMENT Treatment carried out on the surface of lenses which prevents fogging and, being able to spread condensation formed on the surfaces of the lenses in the passage from cold to hot environments, improves the visibility in critical conditions.

ANTI-FOG TREATMENT PLUS Treatment carried out on the surface of lenses which prevents fogging and, being able to spread condensation formed on the surfaces of the lenses in the passage from cold to hot environments, improves the visibility in critical conditions. In conformity with the optional EN 166 requirements, eyepieces with anti-fog treatment PLUS satisfy resistance parameters against fogging (whose minimum provided requirement is a resistance for at least 8 s), thus offering definitely higher performance compared to the standard anti-fog treatment on the marketplace. COFRA indicates such performances by specifying the minimum time of resistance to fogging (expressed in seconds) tested by the certification bodies. Therefore such eyepieces may be marked with the symbol “N”.

UV400 PROTECTION UV400 protection extends protection of lenses beyond the conventional block, rated 380 nm. Such treatment, indeed, allows to filter UV radiations beyond this wavelength, blocking the transmittance of the light spectrum up to 400 nm and helping to protect eyes from a wider range of harmful light rays.

MIRRORED TREATMENT Carried out externally to the lens, covered with a thin partially reflecting layer, it is a treatment that allows a greater reflection of incident light on the lens itself, reducing most of the light that reaches the eyes. This treatment is suitable and recommended for use in conditions of extremely strong light and where it is necessary to be protected against glare (snow and ice).

EXTENDIBLE TEMPLES It consists of a system for length regulation of the temples that allows glasses to adapt optimally to the face of the wearer, thus ensuring the best comfort.

ADJUSTABLE TEMPLES It consists of a system for grade regulation of the temples that allows glasses to adapt optimally to the face of the wearer, thus ensuring the best comfort.

VENTILATION SYSTEM System which, permitting the air to flow, allows to minimize the fogging effect.

SOFT NOSE PAD The soft rubber used for the nose pad improves the comfort of glasses, allowing a prolonged use.

EYEBROW PROTECTION Protection system which, thanks to its softness, makes glasses more comfortable and provides an excellent impact protection against high-speed particles or against accidental and frontal impacts of the operator.

SOFT EAR PIECES Situated at the end of temples and made up of soft rubber, they reduce the pressure of the temples on the head of the operator, ensuring a better adherence and a greater comfort especially in the case of prolonged use.
