Care and Use
Use and maintenance of eyeglasses and sunglasses
ALTRO sunglasses and protective filters protect eyes from the dangerous and unpleasant effects of sunlight. All ALTRO sunglasses meet the essential safety requirements covered by the European Directive 89/686/EEC Directive and its amendments, and are also consistent with the standard EN ISO 12312-1:2013.
The model identification is located inside of the frame. The category filter, as determined by the European standard EN1836 and specified in the table below, appears on the box of glasses you have purchased. When multiple filter categories are present, they identify the class of different glasses filters proposed(models with interchangeable lenses) or if it is a photochromic glass, they identify the category glasses filter in its clearest state and darkest state.
It is not recommended to wear sunglasses while driving in conditions of reduced visibility or at night. ALTRO sunglasses should not be used to look directly at the sun, or as protection against the light from artificial light sources such as tanning lamps. The sensitivity to light and glare, especially in bright lighting such as the presence of snow, on the beach or at sea depends on one person to another. However, it is important to consider the fact that lighting filter categories 0 and 1 only slightly reduce sunlight in the field of vision, while ensuring sufficient protection against UV rays. In normal use, the glasses sun and protective filters provide sufficient protection. However, they should not be used as protection against blows or impacts that could break the glass, causing injury to face and eyes.
Altro sunglasses should be kept in their cleaning bag to a temperature between 35 degrees – 10 degrees C. Avoid exposure to sun without air conditioning in closed environments such on the dashboard of the car, because temperatures reached in these conditions can damage the functionality of the glasses. If the sunscreens are worn (e.g., scratched or opaque), it is recommended to replace with genuine spare ALTRO original parts.
Use warm water and mild liquid detergent. Dry glasses with a soft clean cloth. Avoid the use of solvents, such as alcohol and acetone, and of aggressive cleaning chemicals, as these may impair the functionality of the glasses.
