This causes the soft of future instability,optical glass polarized sunglasses of the curved arc is different,lens assembly of the frame,the lens,the optical refractive standard,loose video,it is difficult to achieve the deformation.Since the curved arc of instability,and the resulting deformation of the lens,it is that bad transmitted image and transparency,is a direct result of the distortion of the image,you can not reproduce the effects of normal visible light.Surface scratches,is easy to wear.

There is no durability.Polarized lenses,thin synthetic resin material of the multi-layer is pressed.Each layer will have a different effect.The middle layer of the polarizing layer,principle is the shutter for stray light to filter the reflected light.Second,it filters the 99.9% of the three harmful UV rays,the intensity of light,functions,and can reduce the difference between ordinary sunglasses.Fourth lens polarization,five so as not to be easy the lens to crack for the shock layer,sixth,after curing of 7,I will wear the easily lens.It is possible to filter harmful rays,polarizer had a role of eye protection.5 Application 1.operation,does not come from the sun and the many problems in front of the vehicle reflection.
2.When fishing,the water sparkling in the light of the sun,but you feel right,it did not feel comfortable with impunity.3.skiing,you can can enjoy the glider,you do not need to worry about reflection and ultraviolet light.4.It is,rainwater overflow of rain clearly exist road traffic signs are available to you in front of your eyes.5.vacation,you can enjoy the sun,sand and leisure time.6 Shopping Tips Sunglasses do not have to be worn only in the summer only,in fact,it should be used all year round.Sunny Wear good,it was cloudy and must be worn.Weather,lightly unconscious,taken more harmful ultraviolet radiation,it is not hot,cloudy day,I do not think the sun is not strong.The quality of the main considerationsThe main function of polarizing sunglasses,UV and polarizing filter,good polarized sunglass lenses are able to penetrate blocking the ultraviolet rays 90%.

You can choose the UV symbol block "UV400" at the best polarized sunglasses.For example,poor quality polarized sunglasses such as dark sunglasses,when the dark of entry human eye,the pupil of the eye increases,ultraviolet rays increases the burden of entering the eye to eye,will increase.Depending on the material true natureChromatic polarization sunglasses,sharp edges of objects that can identify the principle of effective in different colors of light without distortion,you must choose the base color of the surrounding environment.In particular,in order to ensure safe operation,

such as a driver in sunglasses.Infrared,these color lenses for ultraviolet absorption,so that wearing a better effect in the case of air pollution and fog is positive can improve the visual contrast and clarity,The color of the lens,brown,but green is good,in gray.There will be a long-term wear discomfortGenuine polarized sunglasses,in order to wear too comfortable,lens material is also very bad,lens ,,bad health at all inferior to the production of technical and functional,wearing a headache after feeling dizziness,dry eye,tingling ,immediately discontinue use.Please refer to the frame protection.Most frames polarization sport sunglasses,effectively prevents irritation of wind and foreign eye outdoor sports,it is veneered arc design.

In addition,the flexible material of the rigid polarized lenses and frames,it is I will not take into account whether an adverse effect on the human body.7 Notes1 polarizer,it has linear polarizer and (linear polarization) circularly polarized lightPolarizerPolarizerHave access to the same effect as the use of (circularly polarized light); It is possible to pass through the filter,but circularly polarized light is not linear is annular with a particularly suitable autofocus system to the camera.The camera,because it uses a reflective lens,it is possible annular polarizer to ensure the focus accuracy,please use the single-lens reflex unit.If you use a polarizer with a digital camera,since it requires the use of circularly polarized light,inexpensive line bias during use,give affect some automatic focus camera.2 polarizer is generally thick,it is easy to form a Noir to image Otherwise,do not use ?? in combination with the best of other filter.3.
