Glasses not only a real supplies, or a collection of good taste varieties, collection fake oakley sunglasses to keep in mind the following two aspects:

Identify strengths and weaknesses. Concrete from the class, quality, engineering, Ming, ornaments and other aspects of identification. Categories, namely the type of glasses. The classification of glasses, one depends on what era, what style of glasses; second look is plain, old flowers, myopia, or astigmatism. Quality, mainly the lens material. To discern is a crystal stone or fake oakleys, natural or man-made crystal crystal.

Natural and man-made crystal piece crystal pieces differences: First, look at patterns. Crystal chip natural pattern, changes in smooth lines; two is to look at spray (crystal growth in the nodule distribution in various parts of the hardness of the lens is different from grinding polished, hard look at some particularly bright against the light, such as the oil slick floating on the water). Natural crystal spray looks bright and the floating cheap oakley sunglasses lens, the edge of the volatility of the spray pattern direction is consistent with; the edge of rigid artificial crystal lens spray, spray with the pattern to be inconsistent.

Workers, including precision lens grinding, and polishing the edge of the level of processing, as well as frames, mirror box style and fine craftsmanship of the degree. Ming, is whether there is production of glasses logo, name, size, producers name, and whether or not gold, gold logo, such as "Yangmengyuan", "Yu Sheng Xiang" and so on. Ornaments, mainly referring to frames, mirror box patterns, carving level, the level and fine embroidery craft cheap oakleys level, including the mirror box of poems, calligraphy writing characteristics and level, and the art of the mirror box packaging level.

See authenticity. Main methods are: look, touch, try, knock, measurement, ratio. Look to the lens, for example, for the crystal plate and glass of the main differences is to look at the lens surface without scratching the line. Crystal lens, high hardness, smooth surface without scratching the general lines; glass lenses are soft, the lens scared, facing the light and see the scratches on the mirror. Touch, the natural crystal lens always feels cold, artificial crystal lens temperature will be feeling a little longer. Test, the lens Kazakh gas, water, natural gas disappear faster crystal lenses, artificial crystal fake oakley sunglasses lens moisture away slowly. Knock, the two lenses gently collide, clear and melodious voice of the natural crystal lens, artificial crystal lens sound dumb. Measured, using polarized light microscopy, lenses measure table, metering and other equipment to measure the lens material, curvature of the precision, lens transmittance, etc. Ratio is a comparison, mainly the authenticity of comparison, comparing the price comparison.
