How to distinguish true and false Oakley sunglasses on the market?
There are now more and more substandard Oakley sunglasses on the market. So, from which aspects should we judge?
Diopter, Sunglasses belong to the Flat Lens series
According to the national standard, sunglasses are only allowed to have a diopter of plus or minus 8 degrees at most, beyond this error range is an unqualified product. The measurement of diopter requires a professional measuring device “focal meter”, which cannot be evaluated at will. According to the detection of sunglasses on the market by scientific researchers, nearly 30% of the sunglasses have a diopter exceeding the tolerance, and some are even as high as 20 degrees. Experts pointed out that consumers with normal vision wearing such sunglasses are like wearing a pair of glasses for shortsightedness or farsightedness. After a summer, consumers will be “trained” into patients with myopia or farsightedness by inferior sunglasses. When you experience symptoms such as dizziness, nausea, and glare after wearing sunglasses, you should stop wearing them immediately.
Safety performance indicators
Sunglasses with safety performance, whose lenses are made of impact-resistant materials such as PC lenses and TAC lenses, are often marked with “impact resistance”, “approved by the US FDA”, “compliant with the highest standards in Europe and the United States” on the labels and instructions. If the product can meet the requirements on the label, consumers who have special requirements for safety such as motorcyclists and drivers are a good choice. Consumers should learn to protect themselves about the promises made on product labels. Either keep the labels or instructions well, or let the merchants mark them on the invoice. Once a dispute occurs, they will not be passive due to lack of evidence.
Models and Specifications
Models and specifications are generally printed on the temples, not on the legs.
Packaging and accessories and after sales
Genuine glasses should have the manufacturer’s or general agent’s certificate, manufacturer’s manual, mirror box, mirror cloth and some original accessories. The workmanship of the box, frame and mirror cloth is generally fine. Genuine sunglasses should have a complete accessories service of 3 months or more.
Domestic licensed sellers should have brand authorization documents, and there are basically no overseas channels. There is a customs clearance certificate for imported goods, but there is no such document for overseas direct delivery goods. Experts remind consumers that when buying sunglasses, they should go to regular stores to buy well-known brands; when buying, they should try them on first, and compare whether the color difference before and after wearing is obvious, so that the color of objects seen after wearing sunglasses is different. Distortion is appropriate.
