We have two basic ways to see ?? color.Another method,although intended to absorb









700 the visible wavelength range of nanometers.Inversely proportional to the energy light waves and wavelength,short wavelength,high energy.The visible light,the maximum value of the purple energy,minimum energy red light,and the visible light spectrum is ultraviolet light.In fact,it contains a lot of natural light in the ultraviolet.Ultraviolet light of high energy,and due to the ultraviolet energy of your cornea and retina damage.What is glare?

yeezy boost 350 moonrock craigslistUnit of measurement of the intensity of the brightness and light is the lumens.For example,in the room,most of the artificial light intensity is from 400? 600 lumens.Sunny outdoors,if you want to float in the brightness wide range,thousand lumen shade of brightness,high-speed roads and other specific areas,there is a large area,such as the brightness of 6,000 lumens.Brightness following of 3500 lumens,we feel very comfortable to the human eye.When the brightness of direct or reflected light from reaching the 4000 lumens,the human eye will receive light became difficult.We are the white flash that only glare,

New Balance Prix Belgiquein order to see,it tries to efforts to refer to these very bright area.Much of the light entering the eye is decreased because,in order to cause discomfort,we narrowed started.When the brightness reaches 10,000 lumens,light of reason is too your eyes strongly,it will start a completely filter the light.This is such a strong light exposure to bring temporary or permanent blindness too long,can cause damage.On sunny days,large-scale snow,we stare into the light in the absence of any protective measures that lead to the light,it can be up to 12,000 lumens of brightness,reflection "snow blindness."

Casquette Rap France You can perceive the light visible to the human eye.We,we often referred to as white light,in other words,please see the visible light emitted from the sun appears to be colorless.In fact,it is a combination of optical frequency mixing that has been colored.All of mixed color of light ?? flux in the visible spectral range,namely,white,is colorless.(For more information,please refer to the principle of light) ??.We have two basic ways to see ?? color.Another method,although intended to absorb all other frequencies of light,reflecting only a specific frequency of light or reflected a plurality of frequencies,
Nike Lunar Flyknit Sale one of the methods specified object light The frequency is emitted,for example,it can show is light is that like a neon colors,these waves,such as a painted object has been recognized by mixing one color of light,thus It will display the color.For example,yellow light,to see how is the direct target of the frequency of the yellow light,another method may be to absorb light,the green portion of the light mixed after the blue portion and two spectra it refers anti ?? red light eyes were perceived as yellow light.Speaking of sunglasses associated with the light,the following three types of light are important.Direct light - (the sun,etc.),direct light directly hits your eye of light from the light source.

Also a lot of direct light,will now appear the details blur surrounding environment,also to concentrate that it is difficult attention too.Reflection of light - glare of reflected light,in many cases,has a form-based.The reflected light of the reflected light back it will be reflected from the object to the eye.As with direct light,strong reflected light,will be that it is difficult details to appear in perception or object.Snow,water,glass,It is a white sand is a good reflective su***ce.Diffused light - After repelling the scattered light is directed in multiple directions,so diffusing light,the light does not seem to this particular source such.A typical example is the diffused light shine on top of the city.
