Lens colour


The colour of the lenses plays a fundamental role in the management of brightness in the different work activities and in any environments in which they are used. The effects of an unsuitable protective filter colour may cause: decrease of visual acuity, sensation of effort, headache and even nausea and dizziness. Different colours of the lenses allow to promote or preserve the perception of colours, of contrasts and visual acuity; furthermore, they may reduce reverberation and remove UV rays.


Recommended for indoor environments with good visibility conditions and for indoor applications, where the protection of the eyes against impact and most common risks is recommended. Moreover, they help to protect against ultraviolet rays. Applications: mechanical indoor work with good visibility conditions.

Recommended for low-light conditions, cloudiness, mist or fog, seeing as in such conditions, it allows to make objects more visible. Beside perfectly filtering ultraviolet rays (UV) and the blue portion (up to 480 nm) of the visible spectrum, it increases contrast even in low-light conditions. Applications: works in bad weather conditions and in foggy environments, inspection of surfaces, working in tunnels, subsoil working, mines, mechanical working, ultraviolet light exposure, warehouses.

Recommended for well-lighted environments where light causes a considerable eyestrain. It greatly absorbs both ultraviolet rays (UV) and infrared ones (IR), beside keeping the relative proportions among colours. The absorption is almost constant in the visible spectrum while the wavelength changes, so that the chromatic perception is only slightly altered. Applications: outdoor works, mechanical works with risk of glare, agriculture, building, refineries.

Recommended for environments where it is necessary to be protected against intense sunlight, glare, reverberation and all those elements which cause considerable eyestrain. The mirrored treatment on the outer surface of the lens reduces transmittance through a greater reflection of the light hitting the lenses. It is obtained, therefore, a significant reduction of the quantity of light that reaches the eyes, getting a high benefit and a visual comfort even after an extended use. Applications: outdoor works with intense sunlight and with risk of glare, agriculture, building, refineries.

Recommended for intense light and high glow caused by reflective surfaces. Such situations cause a remarkable decrease in eyesight and consequently a considerable eyestrain. This type of lens is able to let the light pass selectively; indeed, acting like “Venetian blinds”, they reduce the overall quantity of light passing through and let only the “useful” light pass through. In this way, reverberation is notably reduced and it is increased the quality of images which appear brighter, consequently even the visual perception is improved. Applications: outdoor works with a high risk of glare, construction site, road work, driving vehicles, oil-plants, work on highly reflective surfaces (water, ice, snow, sand and street surface).

Recommended for anyone frequently passing from indoor (closed and with low light) to outdoor environments (openair and quite enlightened) and vice versa. Being a clear lens with a light mirrored treatment, it provides optimal view in both indoor and outdoor lighting conditions. This lens allows, therefore, a greater visibility and a high identification of colours and shapes during the use in both conditions and during the passage through these two environments. Applications: works with forklift truck, mechanical works, works with the passage between dark and bright environments.

Recommended for protection against impacts, ultraviolet rays (UV), infrared rays (IR) and dazzling caused by welding processes. Applications: works in welding and brazing departments (green 3: brazing and gas welding; green 5: gas and oxyfuel welding, foundries and furnaces).
