At the molecular level, the reflective elements are uniformly dispersed in the surface of the lens to form a uniform film layer, but only half of the lens area covered by the film. This half silvered surface can reach about half its surface reflecting light, and let the other half of the light directly through. Mirror coatings is gradual, paint color depth gradually change from top to bottom. This can strengthen the Tiffany and Co Charm Bracelet Jewelry Outlet sunglasses on top of the light from the resilience, while allowing more light enters from the bottom and horizontally. This means that when you are driving, sunglasses block the sun's rays, while also allowing you to see the instrument panel. Sometimes the coating is a dual gradient, the upper and the lower the maximum color depth of the lens and the intermediate lens are clear.
Coating can easily be scratched. Today, sunglasses manufacturers have not been able to succeed in the reflective coating on the film surface scratch protection layer. Thus, anti-scratch protective coating layer on the lens surface and the reflection film is coated on the scratch-resistant protective layer. Polarization, also known as polarized light. Visible light is a transverse wave, the vibration direction perpendicular to the propagation direction. The vibration direction of the natural light in the plane perpendicular to the propagation direction is arbitrary; polarization for which the vibration direction at a certain moment, are defined in a specific direction. Now anti-ultraviolet radiation is usually divided into two Tiffany and Co Necklace Jewelry Outlet Store glasses and sunglasses polarized lens, sunglasses are familiar we usually block the sun and ultraviolet rays for colored glasses.
Daily lives in addition to sun and ultraviolet rays will produce irregular diffuse through the uneven pavement, water and other places, commonly known as glare. The emergence of the human eye glare discomfort and fatigue and affect the clarity of vision, the polarizer is that we can effectively filter out glare Fake Oakleys Frogskins Sunglasses Cheap for Sale sunglasses. 1 to identify many of the polarizer, wherein one is relatively simple: the two vertically stacked polarizing lens, the lens will appear opaque phenomenon. The reason is that a specially designed lens polarizer only allow parallel light through the lens, both lenses are stacked vertically in the majority of the light is blocked. Everyone at the time of purchase, as long as such a simple operation, they immediately know the authenticity and quality of the product.
At the same time, there will generally identify polarizer identification plate, the naked eye without the black stripes, but bring polarizer looks naked eye you can see the black provisions do not see! Sunglasses no! Generally refers to the so-called polarized linearly polarized light, also known as plane polarized light. Such a vibration wave along a specific direction is fixed, the spatial spread of the route is sinusoidal, and in the projection parallel to the direction perpendicular to the surface of the propagation is a straight line. Plane of the vibration direction of linear polarization component of the propagation direction is called the plane of Cheap Mac Cosmetics Makeup wholesale Outlet vibration, the vibration direction and perpendicular to the plane containing the direction of propagation of the plane of polarization is called. Natural light through the polarizer, the linearly polarized light can be obtained, often used in crystal optics research.
