Sunglasses lens color lens to determine which parts of the absorption spectrum of light. Manufacturers use different colors to produce a specific effect of the use.
1, the color gray is a good general, while reducing the brightness, its color with minimal distortion. Gray lenses provide glare protection, making it ideal for driving and general-purpose choice. 2, yellow or golden lenses can reduce the Blu-ray, while allowing more light through the lens of other frequencies. Because a lot of Blu-ray can bounce and disperse light, which can produce a condition known as blue haze of glare effect. In fact, the yellow part to eliminate the blue spectrum, which makes all objects appear bright and clear. This is why the anti-snow blindness is usually yellow sunglasses reasons. Color perception of these colors will make a little distortion, and therefore not suitable for this type of color sunglasses to identify those who need accurate color activities. 3, amber and brown are also good general color. They can reduce the glare effect, in addition to ultraviolet radiation outside the molecule can absorb its unique higher frequency colors, such as blue. Studies have shown that long-term acceptance of near-ultraviolet light (such as blue and violet) radiation, is one of the risk factors of cataract. In fact, Sun Tiger has a special version called Blue Blockers, with the patent. Such as sunglasses with yellow lenses can cause color distortion, but will increase the contrast and sharpness. 4, the green part of the lens to filter out blue light, but also to reduce the glare effect. In all color lenses, green lenses offer the highest contrast and greatest visual acuity, so popular. 5, in green or blue background, purple and rose-colored lenses provide the best contrast of objects. Thus they are a good choice for hunting and water skiing. Many sunglasses manufacturers use a process known to give a constant density lens staining. This is the most old-fashioned sunglasses manufacturing process, the mixture of glass or polycarbonate materials have the same color. Thus this process in the manufacture of lenses, lens color is inside. Layer of molecules will absorb light in the pure polycarbonate coated surface, but also a staining method. Stained polycarbonate lenses to the most commonly used method is to soak the lens in a special liquid containing the coloring substance, the substance that will stain the plastic slowly be absorbed. If you want deeper color, simply soak in the liquid lens to extend the time. | |
