Sunglasses Categories

What to choose and which ones are best according to the context, place, environment or situation in which you are going to be


First of all and before looking at the categories of sunglasses, make sure they have the certificate EC. There are several things that you have to pay attention to when choosing good sunglasses to protect your eyes from solar radiation. But the most important thing is to check that it has the CE seal, this guarantees that it conforms to the four categories established that tell you how much light they protect you from.

Sunglasses protection categories are set from 0 to 4. Not because they have greater category protection they will protect you better or worse from UV400 radiation since the categories indicate the amount of light transmission that they allow to pass and this is added to the UV400 solar filter. The higher the category, the darker the lenses, and the lower the category, the more light it will let through. Depending on the environment where you are going to move, it will be advisable to use one or another lens category. For example, if you are going to go to the mountains and it is snowy with a radiant sun, the ideal is to use a category 4, but if you are going to drive, you need more light so a category 3 would be fine. In this case, category 4 is prohibited to drive.
