Sunglasses play an important role in protecting the eyes from potentially harmful UV rays. This invisible form of energy in the form of radiation that can damage your eyes if you are overexposed. But the important question is the level of protection I need? Or, in other words, when exactly should I wear sunglasses?
One of the most important factors in deciding whether a particular situation requires the use of sunglasses is the environment in which you areSomewhat surprisingly, exposure to UV radiation is more snow, as well as on sand, asphalt and water, green spaces. Often we imagine, in a park at lunch for some of the most dangerous conditions for UV exposure. But in reality, an environment that reflects the environment, such as snow and water, offer some of the most dangerous situations. This is because in such situations, the amount of UV is not easily absorbed through the green around you, but meets theEarth and is back to his eyes down. This means that you are approaching to UV light, from above and below the eyes have it.
Another dangerous situation where you should be careful to always wear sunglasses, if you are at high altitude. UV rays are filtered into the atmosphere. This essentially means that the gas between you and the sun that are trapped inside the earth appeal to filter UV light before it reaches your eyes. UpHeights, but the concentration of these gases by filtering, as well as their thickness is reduced significantly. As a result, light rays are much stronger, and therefore the presence of UV radiation is much greater at higher elevations.
Now the day is, of course, one of the major risk factors for UV. The direct UV rays of the sun. Therefore, it should be obvious that the risk of UV exposure is greatest when the sun is strongest during the opening hours from 10.00 a clock clock 04:00.At these times the UV rays are more direct and therefore the impact on your eyes are much stronger. It 'so important to take during this period the necessary precautions and wear sunglasses when out.
Weather is another factor often overlooked in determining whether to wear sunglasses. It seems intuitive that, when the sun shines, then ultraviolet rays are strongest, and as a corollary, if the day is cloudy, the risk of UV exposure is virtually nil. This is not theCase, however. Rather, the UV rays penetrate easily clouds, rain, and so on. This means that a cloudy day is no indication that the UV rays are less intense on this day. On the contrary, there is often more important to be litigation to wear sunglasses during the day as we are often unaware of the risks we face to UV rays and take risks with our eyes as a result.
After learning about the dangers of UV radiation, the eyes, the question is not whether Iwearing sunglasses, but when I was wearing sunglasses?
