Lenses of The Sunglasses

Many Cheap Oakley Sunglasses manufacturers use a process called constant density to the lens dyeing. This is the most old sunglasses manufacturing process, the glass or polycarbonate mixture of materials have the same color. Thus such a process of manufacturing the lens, the color of the lens inside. Layer absorption of light molecules deposited on the surface of pure polycarbonate is also a staining method. To the polycarbonate lens dyeing the most common method is to soak the lenses in a special liquid containing coloring substance, such a coloring substance will slowly be absorbed by the plastic. If you want darker, just extend the time of the lens immersed in liquid. Polarized light waves from artificial sources such as sun or even light bulbs are vibration in all directions, and dissemination. Light transmission, reflection, divergence or refraction, when the light toward the vibration of one or more of the plane, we say the light polarization. The polarizing process is a naturally occurring, can also be artificially excited. Each time you observe the lake to see the glare is an example of natural polarization. Glare reflected from the surface of the lake is not able to pass through the lake "filter" light, which is why even if the lake is very clear is not able to see the reasons of the object under the lake. The polarization filter is generally to the surface by a layer of chemical thin films deposited on transparent plastic or Cheap Oakley Holbrook Sunglasses made. Typically, the molecular compounds among naturally arranged in parallel. When they are evenly coated lenses, these molecules formed a tiny lens, able to absorb all the same light with their orientation. Forcing you to wear sunglasses, the vast majority of glare from horizontal surfaces, such as surface and highway. When the light reaches a surface, the reflected light will be polarized, the direction of the surface point of view is the same. Thus, a reflection high-level surface, such as the lake can produce large amounts of the level of polarized light. Therefore, the polarized lenses of the sunglasses is fixed at an angle, making only vertical polarized light can be through the lens. You can observe this principle through the following methods: wearing polarized Cheap Oakley Squared Sunglasses, and then observe a horizontal surface, such as the hood of the car. Slowly to the head left or right tilt. You will find the glare from the surface with your line of sight angle adjustment becomes bright.
