Sunlight people,usually,the light intensity,if it exceeds the capacity

However,this new material is halogen is unnecessary,shows a significant change in the process.And this study,the development of this new material,pointed out that can help to more high tech applications "optical memory" device (laser can be "printed" on the optical memory element to repeat the information via) Island did.10 network language Of network vocabulary from "light"."Light" is used to describe bright spot,humor,what people sent shock,and the like.Sunglasses that block the light,bright things,someone is content,when you publish the contents too great,but sunglasses you can not resist them highlights,the degree of fragmentation even,everyone I shouted: broken my sunglasses! It is the device refers specifically to withstand harsh intended to prevent his glasses that are not informed.Similar alloy sunglasses after,we have derived the usage of sunglasses and other high-strength tempered glass.Sunglasses,also known as a shade for shading.Sunlight people,usually,the light intensity,if it exceeds the capacity to modulate the human eye,it causes harm to the human eye,relies on the adjustment pupil size to adjust the flux.So,in outdoor activities,especially in the summer,you must block the sun visor mirror to reduce the adjustment eye fatigue and light stimulate the harm caused.SunglassesEffect of sunglassesWhile protecting the free eye,sunglasses will be able to block an unpleasant glareSunglassesSunglasses (6)By UV damage.All this,thanks to the metal powder filters,they "choices" is that it can light hits.Colored glass,selectively,for very fine,by using a metal powder (iron,copper,nickel,etc.),you will be able to absorb some of the band composition of the sun of light.In fact when light illuminates the lens,based on the process of the so-called "destructive interference",the light has been cut up.That is,specific wavelengths of light (in this case,the times,UV A,UV B,an infrared),when passing through the lens,the inner lens of the eye in a direction,kill their phases with each other,It is.It is not a coincidence by forming the optical wave overlapping phenomena.
