True and false oakley jawbreaker glasses

In recent years, the cottage products in the mainland market have begun to explode large -scale and construction system. Unlike the previous behavior of sneaking manufacturing, mixing of authenticity and fake, and charging with good times, the current “Li Gui” has begun to make a fake price price. “High imitation”, “fine imitation” and even “perfect details”, the vocabulary layers such as “A cargo” and “ultimate version” are emerging endlessly. When consumers choose products, they have laid one after another “landmine”. Essence

Chapter 1: Buying a cottage in psychological effects is the key

Why do people buy cottage goods? The “pragmatism” and “face” mentality in traditional culture provides a hotbed for fake price buying prices. I saw in a few years ago was still fresh -about two testers who bought two D & G sunglasses purchased as counters, but told one of the testers to wear them. It’s fake. The testers who think they are wearing “fake” sunglasses may be affected by the psychological psychological psychological psychology of wearing fake goods. It performs very unnatural in the next test activity. Compared with the testers wearing “genuine” sunglasses difference.

This experiment shows that people really care about whether the cottage of the product, but from another aspect, can it show that people lack the ability to identify the cottage of the product? Will this be the “rationality” explanation of cottage products -after all, most people cannot distinguish between cottage and genuine products.

“It’s good to use”, “I can’t see it”, these are commonly used rhetoric to buy cottages, but in the eyes of the editor, this is the saying of self -deception. What really affects the purchase of cottage decisions is the ratio of price and quality, and then It is called “cost -effective”, and different consumers have different prices of products, or they are different from “price sensitivity”. When the price of cottage is different from genuine products, buyers naturally reduce the quality of cottage products, and when the quality of cottage is increased, the cost of the product will inevitably increase and lead to the rise in prices. When the price reaches the critical value of his expectation value, he either choose to reduce Requires to buy cheaper products; either add budget and buy genuine products.

In fact, the quality of the cottage’s products can never be compared with the genuine product. In addition to the low imitation of “seeing a fake”, the high imitation and even imitation cottage goods are compared with the genuine product, and they will still show their feet.

Chapter II: Break the inside story of the cottage, the editor test the insurance with the body

In order to unveil the mystery of cottage products, Xiaobian specially selected an object that is closely related to riding riding to analyze, trying to show the so -called “cost -effectiveness” of cottage products, and then explore the value of the authentic money. Provide some references for car friends to buy products.

The protagonist of this article: Oakli ride glasses that are popular in the world: jawbreaker, “same” glasses with cottage.

Oakli Jawbreaker has been popular with O Fan since its listing. Back books, full -scale technology, breakthrough full surround design, of course, ordinary consumers will readily buy it. Of course, the cottage manufacturer will not give up this “opportunity”. The “explosive Jawbreaker” on a certain treasure is hot, and some shops have reached a surprising transaction volume. So what are the characteristics of these cottage Jawbreaker?

First of all, in addition to the same color matching as Oakli’s official, the manufacturers are ingenious and launched a lot of “special color” that even the official nobles. “”. The lenses are also engraved with the word “Prizm” in the lower right corner. So, in addition to color, what are the differences between these cottage goods and genuine products? Is there a difference between cottage goods of different manufacturers?

With these questions, Xiaobian specially purchased a genuine Oakli Jawbreaker (white black color+prizm lens), and bought cottage of the same color glasses and ordinary PC version of cottage and same color glasses, which is known as the “TP90 Ultimate Edition”. Whether there are differences in different manufacturers’ products, they have purchased the “TP90 Ultimate Edition” glasses of another shop as a reference to choose different color matching to show comparison.

How to Spot Fake Oakley TwoFace Sunglasses

Oakley is a company that has been around for over 50 years. They make some of the most iconic sunglasses in the world and are known for their high quality products. However, Oakley Twoface, Oakleys are also very popular knockoffs on the street, as well as in surfing and skateboarding culture. If you’re not careful, you could end up buying a fake pair of Oakley Twofaces In this blog post, we’ll give you some tips to help you spot the real Oakley from a fake so you can buy with confidence!

Check the price

The most obvious way to find out if your Oakleys Twoface lenses are fake is to see how much you’ve spent on them. If you buy sunglasses at a fraction of the MSRP (manufacturer’s suggested retail price), they may not be genuine. The MSRP for each type is set at a specific number to ensure that the retailer gets enough profit for the wholesale price of sunglasses. A reduction in the suggested retail price by more than a reasonable amount should always be considered a red indicator.

Check the outer packaging

All Oakley sunglasses will be packaged in a cardboard box. The cardboard boxes we tested were fairly accurate replicas of the real thing, but they didn’t have any labels or barcodes on the outside to identify what was inside. On its packaging, the copycats used Oakley’s logo, but they were often blurry and low resolution due to the copycat black prizm everyday polarized glasses.

Check the Certificate of Authenticity

Available on any Oakley Twoface authentic sunglasses. As you can see in our movie, some fake frames come with this certificate and warranty card. However, we did notice that the shipping address on the fraudulent warranty card was completely wrong. View Oakley Twoface 009189

Check SKUs

The unique identifier for frame type, size, and color is the SKU (stock keeping unit), commonly referred to as the part number. On the inside of the temple arm, you’ll find it. Sunglasses start with the letters OO, while glasses start with the letters OX. After OO, the four-digit number corresponds to the frame model. After that, there’s a dash and other numbers associated with the colorway. The most straightforward way to ensure an authentic SKU is to enter the full SKU into Google. On the other hand, some knockoffs have the real SKU printed on the frame!

Check lens etching

‘PRIZM’, ‘POLARIZED’ or ‘PRIZM P’ will be engraved on the lenses of every genuine Oakley PRIZM eyewear. Any Oakley glasses that have an “O” on the lens and are not a prescription are fake. However, if you bought Oakley prescription glasses, the lenses will have an “O” engraved on them. If your sunglasses have non-PRIZM lenses, there will be no markings on the lenses.

Oakley Frogskins 009444F will not print or have logos on its regular over-the-counter lenses; instead, any logos will be etched. So if you notice paint on the glass, run it another way. It’s important to note that this only works with over-the-counter lenses. For example, the Oakley “O” may be engraved on the lower corner of a real Oakley prescription lens. Again, a tiny “O” will be cut into shots for ballistic and industrial shots. Matte black prizm for everyday wear with dual lightweight frames.

check stickers

Some fake lenses have stickers on them. For example, the “P” tag is very popular. However, this does not mean that the lenses are polarized. Other stickers are designed to look like lens etchings, but you can tell they’re not when you run your finger along the edge of the sticker. Additionally, the stickers on counterfeit Oakleys often leave residue on the lenses.

Check the hinges

Oakley’s unique frame material, O Matter, is used on most Oakley sunglasses. Because it’s made from pre-dyed nylon, the frame’s color remains the same on all corners and hinges. False edges may chip or peel, and the inside of the hinge may take on a different tint.

Check lens sharpness

Oakley High Definition Optics like the Oakley Half Jacket 009144 ensure your sunglasses are as simple as possible with good lens technology and laser protection products. The image may be distorted or appear larger compared to traditional sunglasses lenses. Oakley genuine lenses provide more precise and accurate vision of the surrounding environment without blurring or blurring of Oakley lens frame materials.

  • Quick visual assessment of product quality.

In most cases, just one look can tell if you’re dealing with cheap knockoffs. Genuine Oakley sunglasses are made of high quality durable plastic, metal and rubber. On the other hand, knockoffs are often hastily cobbled together using the cheapest available materials – which shows.

Spend as much time checking as possible. If a supplier tries to distract you, rush you, or prevent you from handling their merchandise, they may have something to hide.

  • price

The most obvious way to tell if there are fake Oakleys is how much you paid for them. If you’re buying sunglasses well below the MSRP, chances are they’re not genuine. The suggested retail price sets a designated amount for each style to ensure retailers get the right amount of profit from the wholesale price they pay for sunglasses. Cutting the MSRP beyond a reasonable amount should always be a red flag.

  • the quality and clarity of the lenses.

Oakleys are engineered for performance, giving your sunglasses maximum clarity. This means the lenses on real sunglasses will be crystal clear and perfectly coloured to block out the sun while ensuring optimum visibility. Traditional sunglasses lenses can distort the image or make them appear larger than they actually are. Oakley genuine lenses give you a more realistic and accurate view of your surroundings without any blur or blurry distractions.

  • Try on glasses to test their comfort.

The rubber on genuine Oakleys is soft and slightly spongy for a comfortable all-day fit. It should almost feel like you’re not wearing glasses at all. Hard, rough, or ill-fitting ear socks and nose pads are a clear sign that someone is trying to pull fast. Removable ear socks on fake glasses may be easier to move around, or easy to put on and take off when you’re not wearing them.

  • Hinge inspection

O Matter is Oakley’s proprietary frame material used on most Oakley sunglasses. It’s a pre-dyed nylon material, which means the frame’s color is always true to any edge or hinge. Beyond that, arm movement should be smooth throughout its entire range of motion, thanks to Oakley’s sturdy all-plastic hinge. The fake frame may chip or peel and look a different color on the inside of the hinge.

5 Way To Tell If Your Oakleys Are Real Or Fake

Are you looking for a new pair of Fake Oakley sunglasses but don’t know which one to buy? Are you wondering if the pair of Oakley sunglasses you own are real? Due to its popularity, price and patented sun protection technology, Oakley sunglasses are one of the most widely counterfeited designer accessories on the market. As a consumer, it’s not always easy to tell a genuine pair of Oakley shoes from a poor knockoff. Fortunately, the company’s product designs, branding elements, and accessories include a number of features that can help you determine whether the pair you’re looking at is genuine. We have our complete guide to the best Oakley sunglasses of 2022, and we’re here to help you identify yours and judge whether they’re real or not.

1. Check the price

Anything brand new, out of the box, is more likely to be at least in the $80 to $100+ range. Of course, it does depend on the model. It’s always good to check the retail price as well as other frame uses in the same condition. Many factors affect the price of an item, including age, wear and tear, the number of original accessories included, and how much the seller pays for it. Keep this in mind when trying to determine if sunglasses are worth the money.

2. Look at the frame

Many of Oakley’s plastic frames are made from pre-dyed plastic, so the plastic is always the same color. If the frame is to be folded in half, the plastic inside should be the same color as the outside. And those with a design or metal frame that are painted have a high-quality finish that can withstand normal wear and tear over time.

3. Certificate

Ask if they come with a certificate of authenticity or warranty card. You will receive these two documents whenever you purchase a brand new pair of Oakley sunglasses. Documents like this are designed to assure buyers that they are getting the real deal. Beware that glasses advertised as new or unused are not included. [twenty three]

If you are buying second hand, the seller may or may not have the original certificate and warranty card. In this case, you need to rely on other authentication methods.

4. Fake SKUs

If you see SKUs with random letters, they are probably counterfeit. It’s a good idea to plug your SKU into a search engine and see what pops up. Some counterfeiters put genuine Oakley SKUs on their knockoffs, but those genuine SKUs rarely match the models they print. If the model you’re evaluating has an item number on it, take the time to hit it into a search engine to confirm it’s legit.

5.Raised seams

Counterfeit Oakleys tend to have imperfect finishes, and the plastic frame may have raised lines during molding. On real Oakleys, this seam is almost imperceptible. You can pick it out with your eyes, but if you run your fingers along it, you shouldn’t feel it.

The Importance of Owning Cheap Oakleys

Integrating science and art, Cheap Oakleys will redefine product categories and break the limitations of traditional concepts.

Nowadays, the earth has rarely had a mild climate with four seasons like spring. Thus people fall in love with outdoor sports, such as cycling, skiing, rock climbing and so on. Then for the sake of safety, a suitable pair of sunglasses is very important.

First of all, a pair of qualified sunglasses should be used for the following purposes: absorbing and reflecting ultraviolet light to prevent the skin around the eyes from being disturbed by ultraviolet light. Reduce the burden of eye ciliary muscles under strong light and reduce light damage. Prevent sand particles from entering human eyes, etc. These are also the purposes of our purchase of fake Oakley sunglasses.

Additionally, judging whether a pair of sunglasses is qualified is our essential skill – never do useless work. In addition to looking good, we also need to pay attention to the anti UV function. For sunglasses, the UV index is the effect of filtering ultraviolet rays. We should pay attention to whether it has the function of resisting ultraviolet rays. General lenses have anti UV effect. If you want to filter out ultraviolet light below 400nm, you need to see whether there is a sign of UV400 on the lens. Good sunglasses are 100% UV resistant. That is UV400; Ordinary optical resin lenses are generally uv360-uv380 resistant, eliminating 280-400nm wavelength light. At present, the UV index of most sunglasses is between 96% and 98%. Generally speaking, dark sunglasses are better than light sunglasses. The UV index of Oakley sunglasses can meet the above values.

Of course, there is always a misunderstanding when many people choose sunglasses. They think appearance and color are very important, but in fact, comfort is more important. We all know that ski sunglasses have a large internal space, because the larger their internal space is, the less likely they are to fog. If you only listen to this side of the story and buy a pair of huge sunglasses, which are very cumbersome when you wear them, but it backfires. Therefore, the best things are not necessarily suitable for you, and the ones that are suitable for you are not necessarily the best. Just follow your own feelings.

Having a pair of sunglasses that suits you is not simple, but it is very important. They can protect our eyes during outdoor sports. For example, when you are in the vast white ski resort, the sunlight shines on the ground to form a reflection, directly shining on our eyes. On the one hand, many ultraviolet rays will make our eyesight worse and worse, affect our vision, which is easily cause dizziness and danger. On the other hand, there are always many branches on the ski resort. Thus, we need a tool to protect our eyes from branches and other objects.

It can be seen how important it is to choose high-quality sunglasses for sports – Cheap Oakleys!

The difference between real and fake Oakley sunglasses

I did some research when buying sunglasses to prevent me from buying fake Oakley sunglasses. The Oakley brand was created in 1975. American science madman Jim Jannard is the founder of this brand. You may not know that they started out with not sunglasses but motorcycle handles. I’m curious how they transformed. But Oakley’s ultra-high-tech sunglasses completely fascinated me. HDO high-definition optical technology was invented by Oakley. This shocked me very much. I always thought that sunglasses were simply used to protect from light. It turns out that they can also make the vision clearer. They even block UV rays as well as glare and harmful blue light. We use sunglasses in life and sports, so they also have a high degree of impact resistance. This can prevent a certain degree of damage to the eyes.

Fake Oakley sunglasses are bound to be worse in this regard. They may not be as sturdy and have less protection from light. What amazes me the most is that the Oakley waterproof lenses also eliminate static charge. This also means they won’t be covered in dust. Their protective layer is amazing. But if it is not genuine, this function will be weakened. So this can be the basis for our judgment.

Oakley’s ultra-high performance meets the needs of professional athletes and can also be used by the military. I’ve observed that Oakley sunglasses come in a lot of colors and look great. So they are equipped with the function of freely removing and changing lenses and even temples. I have to say that the designer is very thoughtful. I have a brief understanding of their fashion styles. As the top brand of outdoor sports sunglasses, it is also very outstanding in fashion. They have many types of lens shapes. Coupled with unparalleled high performance, they are sought after by many celebrities.
Based on the above information, I fully understand Oakley’s positioning in the market and the technical content they have. Therefore, we can think that the top sunglasses naturally have a high price. But often someone falls into the price trap. Fake Oakley sunglasses on the market aren’t usually cheap either, but they’re still a lot less expensive than the real thing. These sunglasses are almost identical in function and appearance to the real thing. When you’re not obsessed with true or false, fake Oakley sunglasses are a good choice. But I still put together 2 identification methods for your reference.

  1. Check workmanship and details
    First of all, we need to know that Oakley sunglasses have many styles and styles, such as limited edition, military edition, sports edition and so on. For the military version, information such as the production date and brand logo will be engraved on the inside of the frame. You should note that these engravings are laser engraving. They are very smooth. Secondly, there will be a brand O-shaped logo on the temples. Usually where the frame and temple meet. If the details are rough then there is a good chance they are fake. Not to mention that they are misaligned or discolored. Another point that is easier to ignore is that the model and focal length of the sunglasses are also marked on the sunglasses. You have to look for it.
  2. Check the packaging
    Oakley has carton dust bags and instruction manuals. The most important thing is the warranty card. The printing quality of the packaging box is very important. You can tell from the color and clarity of the ink used. Secondly, there must be a white label on the side. There are two different barcodes on the label. What you have to do is judge whether the information is consistent. If it doesn’t match, it’s definitely fake. If you have a dust bag, you can check to see if there is any excess thread. After all, it is impossible to open the line under the level of high technology. The logo of the oval letter O can also be seen if it is on the surface.

How To Remove Scratches from Sunglasses

Scratches on fake Oakley sunglasses lenses can reduce clarity when looking at objects. If knockoff Oakley sunglasses designed for sports such as skiing or golf are scratched, the polarity of the lenses can also be affected.

Buy white toothpaste without abrasives.

Toothpaste must not contain mint, gel and whitening ingredients. Cleaning your lenses with regular white toothpaste works best. Toothpaste with special ingredients can cause further damage to the lens. Baking soda toothpastes from brands such as Alwomei are also a good choice for cleaning your lenses, as these types of ointments do not contain abrasive chemicals.

Squeeze a pea-sized amount of toothpaste onto a cotton ball.

Squeeze as little as possible so that excess toothpaste doesn’t smear the lenses all over the place. Wiping the lenses with a cotton ball works best, as no shed fibers will remain on the lenses after wiping.

Rub the scratched area with a cotton ball.

Rub the lens in circular motions. And rub each scratch for about 10 seconds. Doing this will help smooth out scratches.

Rinse off the toothpaste from the lenses.

Turn on cold running water and rinse off the toothpaste. While rinsing, rotate the lenses to make sure all the toothpaste is rinsed out. Toothpaste may be hidden in the gap between the lens and the frame, so you need to pay special attention to these places when rinsing.

Wipe off toothpaste with a soft, lint-free cloth.

Do not wipe your glasses with a coarse or dirty cloth, as the lenses are easily scratched again. Use your thumb and index finger to carefully rub around the scratch with a lint-free cloth to remove any remaining moisture or toothpaste. Do not press too hard or the lens will fall out of the frame.

Check the lenses. Check your sunglasses under a light to see if the scratches are still there. Then, put on your glasses and check the lenses for scratches. If scratches are still noticeable, rub the lenses again with toothpaste and a cotton ball. Rub it a few more times until the scratches disappear.

Mix water and baking soda

Prepare water and baking soda. The alkaline component of baking soda is great for breaking down acidic residues on your lenses, allowing them to regain clarity. A thick paste of baking soda and water can remove scratches and clean your lenses.

Mix one part water and two parts baking soda in a small bowl. The amount of water and soda used is largely determined by the size and number of scratches. You can start with a tablespoon of water and two tablespoons of baking soda and increase the amount if the scratches are severe.

Choose the right lens material

Choose scratch-resistant lenses

Fake Oakley Sunglasses are useless after being scratched. Lenses made of NXT polyurethane are impact resistant, flexible, lightweight, and have high optical clarity, but are expensive.

Glass is heavier, more expensive, and “cracks” when dropped.

Polycarbonate has less scratch resistance and optical clarity than NXT polyurethane or glass, but is more affordable.

Polyamide is a lesser-used material that provides glass-like optical clarity without the risk of shattering.

The scratch resistance of different polycarbonate lenses varies significantly, depending on the hardcoat surface used in production.

Acrylic materials are less expensive, but have the worst durability and optical clarity. They are also less heat resistant and often deform. Glass or resin material is the best choice.

Choose the suitable frame

Fake Oakleys with Round frames are suitable for square faces, rectangular frames are suitable for heart-shaped faces, and square frames are suitable for round faces.

If your eyes are smaller, you can try choosing darker lenses, which can make the eyes appear larger.

Remember to check that the lenses are smooth and free of scratches, air bubbles or spots before buying.

Check that the sunglasses are the right size and won’t slip off your face. If you’re playing sports, you need to be aware of your surroundings, and your sunglasses could be thrown out if you’re not careful.

When traveling, be sure to store your sunglasses in a hard case for protection; otherwise, you could sit on it and crush your sunglasses.

Make sure the sunglasses look and feel right on your face. Sunglasses that are too small or too big, too heavy, or look good but don’t feel comfortable are not for you.

Be sure to check that the lenses are dark enough.

Sunglasses with light, white or pink frames and lenses will stand out on darker skin.

When not wearing, keep your knockoff Oakley sunglasses in a safe place to avoid scratching the lenses.

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.

Product channel

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.
