Replica
There is a lot of controversy over the use and manufacture of replica sunglasses. Not everyone can or is willing to pay out $100 to $400 for a single pair of designer sunglasses. Replica sunglasses can be obtained for on average about 10% of this designer cost. The look of the sunglasses is the same but the primary concern of the name brand designers is that the replica sunglasses are not produced with the same quality materials and long lasting durability of the originals.
Because of this lesser quality construction coupled with replica sunglasses makers even going so far as to place the brand name on them, designer sunglass manufacturers feel their reputations are being ruined. It is illegal to sell these lower quality exact replica sunglasses although it is not illegal to buy them. As an alternative, one could search only for those replica sunglasses makers that advertise as being "like" this brand or the other and that carry a logo that is not an exact copy of the designer brand. While these companies do stay on the legal side because they do not advertise their products as "original", the quality of their replica sunglasses is still lower. Where name brand designer sunglasses are constructed with high impact polycarbonate plastics or metal which can last for years, the replica sunglasses are usually made with cheaper, more brittle plastics that will not stand up to the wear and tear of the originals.
Some replica sunglasses makers will still provide a decent quality product on the sunglasses they mimic. A good pair of replica Oakley sunglasses from sunglassesmall.com may still run you $40 for a replica half jacket style. And while their seven-day warranty against factory defects hardly compares to a year's warranty from Oakley itself, they do try to provide replica sunglasses that are made well enough as to not be below par when it comes to ultraviolet radiation blocking.
One thing that makes it tempting for retailers to offer the replica designer sunglasses is that you can purchase a bulk quantity of these exact copies at wholesale for what one pair of the original designer sunglasses cost. Bvlgari replica sunglasses, Locoste and Christian Dior are some other designer brands that are very commonly replicated by copycat manufacturers.
One should always check to see that the replica sunglasses they purchase have at least been made with polarized lenses. Some replica sunglass manufacturers will try to mimic polarization by using colored plastic lenses. These do not provide the anti glare benefits of polarization and often do not even meet the minimum standards of UV blocking for vision protection.
