You recognize a good pair of sunglasses
When buying sunglasses, you should not rely on well-sounding names, because these are often misleading. Terms such as 100 percent UV protection sound good, however, it is not really. Of very cheap sunglasses, you should let the Finger, if you carry the CE mark. Regardless of the fact that the CE mark is not available for the best protection, it is a fake also and you hardly have to test a possibility of the own.
- The CE mark States simply that the sunglasses meet the requirements of the appropriate EU Directive. These Minimum requirements must glasses all the sun, which will be sold in Europe, fulfil.
- Accordingly, the CE symbol is not a special quality feature, but merely States that the sunglasses meet the minimum requirements. And the minimum requirements are quite modest: The sun glasses offer UV protection up to 380 nm. This is according to the EU Directive as 100 percent UV protection.
- This in turn means that the full-bodied advertising slogan 100 percent UV protection is also no special additional quality feature of the sunglasses. Strictly speaking, it is even misleading the consumer, because the CE mark implies this statement.
- Basically, the sun are divided into levels of glasses in four of protection. Glasses, which have only the CE mark, are usually located only in protection level 2. From the dangerous UV rays protect glasses eyes not really.
- To be on the safe side if you are with a sun protection level of 3 glasses. These sun glasses they can see on the label UV 400. Protect your eyes against UV-rays with a wavelength up to 400 nanometers. The sun keep glasses the protection level 3 is also the dangerous rays from your eyes.
- Only if you are on snow-covered mountains, is the highest protection level 4 is required. So you are also protected from photo-keratitis, the so-called snow blindness. Note, however, that the sun protection level of 4 glasses will not be allowed to wear on the road.
- That sunglasses protects the better, the darker the lenses are, is also a truism. The opposite is the case. You wear a pair of sunglasses with dark lenses, but a low level of protection in case of strong sunlight, you can cause damage your eyes. Through the dark glasses, the pupils, and the UV-wide automatically-rays of the eye can hit with full force.
- Well, however, dark glasses are glasses in combination with protection level 3 are. In addition, the sunglasses should have a wider strap, so that the sun, the eye meets the light from the side.
Behind the sunglasses the eyes well-conceal, however, we can tell you that helps.
