LENS TREATMENT

 ANTI-SCRATCH-TREATMENT-ico

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-vert-ico

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 antiscratch 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-ico

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-vert-ico

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-ico

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-ico

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).
