High quality sunglasses are very effective "regulator". Sunglasses can regulate inward light, making it suitable for the human eye.Oakley Frogskin Sunglasses In the next section, our sunglasses.Regulation will be adopted by the Council on the sunglasses manufacturer of optical technologies. In order to gain a better understanding of these technologies, you must first know something about the light of knowledge. A beam of light with a certain amount of electromagnetic energy.Cheap Oakley Frogskin Sunglasses Size of a wave is measured in wavelengths. Visible light wavelength range from 400 to 700 nanometers. Wave energy is inversely proportional to wavelength, the shorter the wavelength, higher energy. In visible light, violet energy Max, red energy minimum, and is above the visible light spectrum ultraviolet.Oakley Frogskin Sunglasses Outlet In fact, natural sunlight contains large amounts of UV radiation. Due to the high energy UV, ultraviolet rays can have on your cornea and retinal damage. What is glare? Lumen is the unit of measure of the brightness or intensity of light. For example, in the Interior, most artificial strength of 400 to 600 lumens of light. If the sunny outdoor, brightness are floating in a very large range, the shade has a brightness of 1000 lumens, such as highway where there are large concrete,Oakley Frogskin Sunglasses Sale 6,000 lumens brightness. 3,500 lumens of brightness, our eyes are feeling very comfortable. When direct sunlight when the brightness of the light or reflected light reaches 4,000 lumens, human eye receives light start to become difficult. When we try hard to look at these very bright areas will only see a white Flash,Oakley Sunglasses this is the glare. In order to reduce the discomfort due to large amounts of light entering the eye, we begin to blink. Once the brightness when it reaches the 10,000 lumen, your eyes receiving the light is too strong to start a full filter light. Exposure to strong light over long period of time can cause injury,Cheap Oakley causing temporary or even permanent blindness. On a clear day, the reflection of a large snow up to 12,000 lumens brightness can, if we open with in the absence of any protection measures that light would result in "snow blindness". Visible light is the human eye can detect light. Issued by the Sun's visible light we see is colorless, that is, we often say that the white light. In fact, it is a combination of frequency mixing colored light. In the visible light spectrum all within a shade of light was colorless, blend, that is white.Cheap Oakley Sunglasses (For more information, see principle of light). We have two kinds of the basic way of seeing color. One way is itself an object of which can issue certain frequencies of light, for example neon light is color; the other a way of absorbing all other frequencies of light are objects, and only certain frequencies of light reflection, or reflects a variety of frequencies of light, these optical mixing and the perceived color of light, such as coated with the paint color of the object is displayed.Oakley Frogskin For example, to see the yellow, one way is direct yellow frequencies of objects of light; the other is the absorption of blue light in such a way, reflecting the red and green light, eyes of the mixture of two kinds of light was perceived as yellow.
