The good choice of the Solar glasses It is of great importance to care for the health of our eyes. The best thing is to let yourself be advised by a professional, but a few basic notions, not to get lost among the multitude of options is presented to us, is undoubtedly essential.
As I said in the previous post, it is important to not be based only on the aesthetics eyewear, but find that better adapt to our specific needs, although in these times the range of possibilities that we offer lenses are innumerable.
The Norma European sunglasses (UNE) establishes a classification of the Solar filters into five categories, each one determines the absorption of each one of the filters to light and ultraviolet radiation.
- Category 0: Let go at least one 80% of the light visible. Especially for low-light environments and indicated, in interiors, for people who suffer from photophobia.
- Category 1: Photochromic lenses or lightly colored. Special for use in city.
- Category 2: Recommended for sport, com bike, run,…
- Category 3: Suitable for sunny areas, beach and mountain. More apopiadas for the summer.
- Category 4: Especially indicated torque zone of high mountains, skiing and water sports. This type of lens is unadvised for driving.
Then there are the different types of filters that can be found, usually tend to be three. The Brown filter is that most alters the colors, i.e. how we perceive them, but enhances the contrasts, widely used in sports in winter and on the mountain. The Green filter little alter the colors, recommended for nautical sports, although suitable split all uses. The grey filter It is that shows colors in a more natural way, so it is preferable for prolonged daily use and driving.
In my opinion it is important to choose a good sunglasses for the proper protection of our eyes and our children. It is important that they choose, so we guarantee that they use them, but marking a specific parameters on the most appropriate for their age and condition. If our son does some kind of sport-specific, we should opt for glass suited to those conditions. If not we can purchase a standard glass, but always with guaranteed checks. A bad glass It can cause more damage in the absence of this retina.
It is important to explain the damage that we cause the Sun’s rays, raise them from well small on the correct use and choice of sunglasses, not let us drag only for aesthetics, but for the same functionality. In pharmacies and optics we can find models different for each age and taste, guaranteeing their quality and safety, this is the best option and so we must explain it so that they see the importance that has.
