Amber and brown are also good common color. They can reduce the glare effect, in addition to ultraviolet light, in which unique molecules can also absorb higher frequency color. Long-term acceptance near ultraviolet light irradiation is cataract pathogenic factors. Sun Tiger has a special version called Blue Blockers, owns the patent. Such as Cheap Oakleys sunglasses with yellow lenses can cause color distortion, but it will increase the contrast and sharpness. Green lenses can filter out some blue, but also reduce glare effect. In all color lenses, green lenses offer the highest contrast and greatest visual acuity, so popular. In the green or blue background, purple and pink lenses can provide the best contrast of objects. So they are a good choice for hunting and water skiing. Many sunglasses manufacturers use a process called to give a constant density lens dyeing. This is the most antiquated sunglasses manufacturing process, the glass or polycarbonate mixtures of materials are the same color.
A layer of light-absorbing molecules deposited on the surface of pure polycarbonate, is a dyeing method. A polycarbonate lens dyeing most common method is to soak the lens containing a coloring substance in a special liquid, the coloring material that will slowly absorbed by plastics. If you want deeper color, simply extend the lens immersed in the liquid of the time. Whether light is transmitted or refracted when the light is in one or more vibration plane direction, the polarization of the light we say. Polarization process can be naturally occurring, it can be manually excited. You see when each observation glare lake is a natural example of polarization. Cheap Oakleys Glare reflected from the lake is not able to filter through the lake of light, which is why even though the lake is very clear and not be able to see the lake, objects cause. Only the gap and the filter portion of the light in different directions in order to pass through it. Other light rays will be absorbed. After a post- filter polarized light is considered.
Polarization filter is generally film by chemical plating layer on a transparent plastic or glass surfaces made up. Typically, the compound used between the molecules is arranged in parallel nature. When they are evenly coated on the lens, these molecules form a tiny lens, they can absorb all the same as the arrangement direction of the light. Forcing you to wear Cheap Oakleys sunglasses most of the glare comes from horizontal surfaces, such as water and highways. When light reaches a surface, the reflected light will be polarized direction of the same angle with the surface. A high level of reflection surfaces, such as lake, can produce large amounts of the horizontally polarized light. Polarized sunglasses lens fixed at an angle, so that only vertically polarized light through the lens to. You can use the following method to observe this principle, wear polarized sunglasses, and then observe a horizontal surface, such as a car hood. Slowly tilt head to the left or right. You will find the glare from the surface of the eye as you adjust the angle becomes brighter.
