On many occasions we let ourselves be carried away by a frame of beautiful sunglasses regardless of their other conditions and without measuring the impact that these may generate in the future, since most likely they do not meet the conditions of sunglasses and we think so or use them. as if they were, leaving aside the true protection that should be given to the eyes from the sun’s rays.
Remember that solar radiation is now stronger and more direct, causing irreparable damage, therefore the importance of protecting our body from it, the face, neck, lips, hands and of course the eyes.
According to experts, lenses are classified into several categories ranging from 0 to 4, with 0 being the lightest and 4 being the darkest. This is the classification given to the sunscreen according to its intensity regardless of color. Here I leave this table that better explains the classification and for which case each of them applies.
It is valid to bring to the subject the lenses that we know as transition that darken in the light, in places where there is greater sun exposure and darken indoors, normally these lenses handle two categories, one for when they are clear and another for when they darken: 0-3 and 2-4. These are ideal because they adapt to the event, being ideal for any case offering excellent protection from solar radiation.
Remember that we can find them in different shades or colors, the important thing is that they effectively offer protection against UV rays, that they meet the minimum established standards and that they adapt to your style and daily work.
