    Reasons why wearing sunglasses at work is vital

    The side effects of being exposed to the sun without eye protection are not immediately appreciated but accumulate over time and cause retinal burns, photoretinitis, photo-keratitis, photo-conjunctivitis and induce the appearance of cataracts. The WHO warns that approximately 18 million people worldwide are blinded by cataracts that can be attributed to exposure to ultraviolet radiation. This is reduced with the use of protective glasses, and may even make these effects disappear completely. Our sun protection glasses are classified as PPE of different categories, but always certified with the EN166 and EN172 regulations.

     

    What is the indicated use for each category of sunscreen

    Knowing and knowing how to interpret the filter category of a sunglasses is one of the most important things when choosing. When we buy a sunglasses it is always accompanied by a small brochure or marking on the sunglasses that specifies a number from 0 to 4: this is what we call the class or category of sunscreen and indicates its intensity, with 0 being the most light and 4 the darkest. Assigning them a number that allows us to typify them can help us suggest uses and indicate limitations, regardless of what color the lens is. Then we leave you a guideline where the light transmission and the environment indicated for each of the solar lenses are shown.

    Filters needed for work sunglasses

    Sunscreens for work use must have absorption of visible, UV and IR radiation. Here are some recommendations for the options of solar eye lenses:
    Optical class: This can be 1, 2, or 3.
    Resistance to surface deterioration by particles: marked with the symbol K.
    Fog resistance: marked with the symbol N.
    High reflectance in the infrared: Marked with the R symbol, recommended for long exposures and high heat levels.
    Photochromic Filter: that reversibly varies its transmission in the visible and ultraviolet depending on the light intensity.
    Polarized Filter: It prevents the passage of light that reflects on objects.

    Knowing what type of glasses to choose for work use is that easy

    You must take into account if your activity is indoor and outdoor, if so you will choose a photochromic lens. If you work in environments with greater glare, with water or liquids, crystals such as driving, the most recommended lens is the polarized one.
    If your work activity requires a complete lateral view produced by a high risk in the environment, you can consider the option of a panoramic glasses like the Aventur, in all its lens variants, depending on the desired intensity. For work with risk of external impact, there is also the option of a sunglass with an internal foam protector, which seals the eyepiece very well.

    Frequent questions

     

    What does UV 400 mean in sun safety glasses?

    That the lens is prepared and treated for complete protection against ultraviolet radiation that is composed of non-visible rays with a high energy from the sun and that are not useful for vision.

     

    How to know if my industry sunglasses are polarized?

    Forming a 90 degree angle (L-shaped) with two lenses of this type. If an almost total darkening occurs, it is concluded that they are polarized.

     

    What is the role of photochromic work glasses?

    Save yourself a double cost, since in a single glasses you have a colorless and a solar, since their lenses automatically darken or lighten according to the light exposure. It also saves you the inconvenience of wearing two glasses, and having to graduate both, since in one you have everything! You can know more here.
