When driving at night,in order to monitor the high beam on the road,flash photography will cause damage to the intense irritation and eye.The car from the normal or less was in also about 5? 8 mm automatic contraction of small 1mm after it will be too late,multiplied by the pupil to light stimulus of light,the human eye,so many more can,of light for the original amount of the 16 minutes of the pupil response is reduced to one,the same phenomenon forward light,plunged night blindness,it has occurred on many of the accidents occurred [1].The people's eyes to the bright light resistance small,the irradiation light,in many cases,is the allowable range of the number of times of the human eye.As the photopolymerization eyes,hundreds of times when strong light intensity is doubled,in order to reach the cornea than thousands of,and through the eye retina.[1]Safety solutions of night driving1 normal sunglasses and the mirror: You only have to wear during the day,appropriate,night driving seriously vision (national standard night driving glasses light transmittance shall not be less of> 75%),average transmittance of less than standard sunglasses It can affect the rate.[1]No driving mirror of pale yellow light barrier effectBlocks the driving mirror ineffective,pale yellow light (2)2 normal pale yellow gradient night and all-weather driving mirror driving mirror:;,the same weather driving mirror can be reduced glare,
cheap jerseys from chinabut darkened affect safety vision of the road,the normal pale yellow of the night vision goggles is the only 20? Just be able to cut off 30% of the light-shielding is not enough night driving glasses,does not meet the national standards [1].3 light barrier,bar,night vision treasure dimming: driver of the field of vision,form vision blind of some of the car to block glass front Place further object of the dimmer before,and the vehicle of such obstacles .They headaches,over a period of dizziness and nausea,time to cause side effects,the driver's eyes always shaking bumps,and not fragile secure some products [1].Wearing night vision goggles pair of transmittance were affected of the main lens,but you need to> 75% of the observation of the road,a pair of good night driving mirror,other cars on top of the 80% should be able to stop the light,you will be able to ensure good driving driver road safety.[1]22 fashion of process Sunglasses,
Cheap iphone caseand or first appeared,you shut off the sunlight.1752,JamesAyscough first green or blue of the spectacle lens manufacturer.Although he revered ancestor sunglasses after,he was able to improve the only human vision problems and become such a design.According to the 12th century,worn by official great people of China,Liu Chibukku "Guiqianzhi" record,"sunglasses",this "sunglasses",the other of which are manufactured in smoky topaz so as not to block the glare of the sun Although people so as not to see his reaction,when I heard the confession.In addition,sunglasses at the start of the function of the present invention and shadow,I think a very different way.With the rise of the second innovation,shading and eye function more clearly sunglasses.The manufacture and use of the car of aircraft,sunglasses,will be that it has entered into public view.At that time,almost all types of convertible aircraft,strong in order to shield the wind and bright sunlight,indispensable become one of the pilot of the items,sunglasses attention shading and eye function more in the design.Lift fashion sunglasses,is an American pilot and "Le Pen" definitely the biggest contributors.The pilot early 20th century that had to be faced with a strong mission in the eyes of the damage caused by sunlight,.In addition,part of the pilot after the flight,
nike shoesnausea,vomiting,there will be dizziness side effects,also,because the special recourse that was called the company of Ray-Ban of Bausch & Lomb,US Air Force Lieutenant,their pairs a lot of light production sunglasses can be absorbed.After repeated experiments and research and development Ray-Ban,and finally not only beautiful in 1930,not only to prevent the UV eye sunglasses,and success in the development of this.Sunglasses Initially,this new invention,there simply pilot goggles.Then,it absorbs sunlight,little difference in heat and vision,in order to facilitate opening,subsequent US gradually,that is not only able to have a protective effect has been found.Since many of the girls of mind of US soldiers become prince,as a result,good looks and neat uniforms and cool sunglasses,wind.During the Second World War,US Admiral MacArthur,he smoked a pipe,the image of 佩戴 thunder popular friends,you are wearing off the sunglasses,the people also,some to the general sunglasses hero of love I asked.Ray-Ban sunglasses,has become a famous brand sought after by the public.Polarizer,the clear vision so the nature of the light,to be able to track the transmission axis in the visual image of the eye,in order to eliminate stray light,are manufactured in accordance with polarized lenses and the principle of the filter of the light.
Ugg Boots OutletSunglasses,and is used in the lens of the camera.Operating principle PL is the role of the mirror to increase the contrast,it is reflected in the optical filter.It works by filtering the light from the selectively specific direction.Sky dark pressure,thereby weakening the intensity of light in the sky,it can increase the contrast between the thing door blue sky and white clouds filtering the many diffusion of polarization.The darkest in the sky of the viewfinder,the darkest between the most appeared 90 degrees,and look through the viewfinder to rotate by shooting the most obvious difference between the mirror effect,specific.You the most dark and there may be a need to move to any of the angle between the bright.By adjusting the polarizing plate can be effectively filtered in PL lenses,weaken,or generally polarized to eliminate reflective metallic surface (metal surface,the light does not operate polarization microscopy,polarized is reflected back not) can reflect light quality improves,so as to increase the sharpness of the screen and reflects this part of the subject.As fish clear water is captured,for example,by using a polarizer,it is possible to reduce reflection surface.When you shoot such a scene,there is a tendency that the projection angle of the light source and the camera of the camera angle is consistent,need the maximum deflection angle between 30? 40 degrees.When you turn the front lens group to slowly adjust,you can use the time to filter through efforts to the reflecting surface in order to minimize the scene.Further,the polarizing plate,a polarizer as image capture is more pure,since it is possible to absorb the stray light reflected in different directions and dusts or mists in the air,improve the contrast,
Adidas Springblade color saturation It can be improved.For example,in many cases,in order to photograph the colorful pictures,and using a polarizing microscope to take still pictures,flower photo.In landscape photography,and useful flower photos,and when photographing a specific relatively strong reflection landscape.landscape drawn to the excellent result,a polarizing plate is used when shooting a cloud.Light blue sky and white clouds refractive index of,is much larger than the scattered light.Polarizer also,you can green of the leaves to use a more elimination of saturated colors and low angle city scene shade fog.2 composition And a polarizing plate body,into two parts by the lens and the lattice consisting of microcrystalline glass attached,the seat back frame to rotate the lens body it.When rotated,the person who is not a grid polarizer likely,it will be polarized parallel to the line that was blocked.Thus,control,a polarizer for selecting the parallel light reflected record number (this is the light that was reflected polarized).This is the polarizing plate can be removed or reduce the non-metallic surface reflection of the truth.However,it was bluish most polarizing microscope a little.To stop while shooting in vibration,it will be the polarization direction of the same portion of the non-polarized light.To avoid color screen,a plurality of files in order to increase the exposure is generally too dull.Classification By usingSki gogglesFishing mirrorPolarization drive mirrorOutdoor Sports mirrorGolf GlassesMaterialGlassResin materialTAC lens materialAccording to the principle point,Circularly polarized light microscope (below CPL)Linear polarizer of (referred to as LPL)LPL is mainly used in the old-fashioned manual focus camera.Add a layer of 1/4 wavelength of the film,after,this film is CPL display have special properties,in one direction (eg,x) while its vertical,/ 2 phase shift π polarization of the electric vector You can generate the electric vector direction (assuming y) it has no effect.
