principle

Description

principle High quality sunglass is very effective “light stabilizer”. Sunglasses can regulate foreign light, make it suitable for the human eye. In the next section, we will introduce the sunglasses manufacturers various oakley technique. Adjust light To better understand these technology, must know something about the light of knowledge. A bunch of waves have certain electromagnetic energy. Wave to measure the size is the wavelength. The wavelength of visible light oakleys scope for 400 to 700 nano. Waves of energy and wavelength, the shorter the wavelength is inversely proportional to the higher, energy. In visible, red lights, largest minimum energy of energy in the visible spectrum, and above is oakley glasses ultraviolet light. In fact, natural light to contain a lot of ultraviolet light. Due to the high energy, uv ultraviolet radiation to your cornea and retina produce damage. What is the glare? The intensity of light brightness or unit of measure is lumen. For example, in indoor, most artificial light intensity for 400 to 600 lumen. If outside oakley minute in the sunlight, brightness will a wide range of the brightness of the float, the shade, and for 1000 lumen like highway where such a large cement for 6000 lumens brightness. The brightness of the 3,500 lumens below, we all feel very comfortable eye. When direct light or the brightness of the light when arrive 4,000 lumens eye receiving rays began to become sweaty. When sunglasses oakley we try to try to look at these very bright area, only will see a white flash, that’s glare. In order to reduce light into eyes because of massive caused discomfort, we start narrowed eyes. Once when lumens brightness reach 10,000, your oakley ski goggles eyes because receives the light overpowered and start completely filter to light. In such a strong light exposure for too long can cause damage, leading oakley goggles to temporarily or even permanent blindness. On a clear day, a big snow reflected by the brightness up to 12,000 lumens, if can no protection measures in our the situation look these light will lead to “XueMang”. Eye visible light is light can be Oakley Water Goggles Discount perceived. We see a visible light from the sun is a colorless, also looks is that we often say white light. In fact, it is by a variety of frequencies Oakley sport Sunglasses Discount of a color mixture. In visible spectrum are all within a mixture of light color is a colorless, namely white. (for detailed information, please see light principle). We have two basic ways to see color. One way is an object itself can emit certain frequencies of light, such as neon is this Oakley Snow Goggles Discount shows color; Another way is absorbed by the object and all other frequencies of light, and only reflect certain frequencies of light, or reflects various frequencies of light, the light is mixed one color of light perception, such as coated with paint such is the object shown that color. For example, must Oakley Polarized Sunglasses Discount see the yellow light, a way is object an immediate yellow frequencies of light; Another way is absorption spectrum of light, medium blue part reflected the red and green light, this part after mixing two light for yellow eye perception by.
