1. 580 Etched on The Lens

1. 580 Etched on The Lens

The first and most common way to know whether a Costa sunglass is fake or real is by noticing through the lens. 

You’ll see the number “580” engraved on the left lens of your sunglasses. This number indicates the lens material and at the same time, the authority. 

When you notice a “P” text after the number “580”, assume that the lenses are made of plastic, and when you see “G” after 580, assume that the lenses are created from glass material. 

Additionally, notice on the temple arm where the Costa logo is Etched.

2. Notice At The Product’s Pack

Costa offers a case and a cleaning cloth with every single product. That means when you buy sunglasses from Costa, your sunglasses pack will include a case and a lens cleaning cloth.

However, when you buy a fake Costa eyeglass from a fake seller or company, there is a high chance that the seller will want to give you more things with the pack such as extra lenses, extra frames, and a lens cleaning cloth. 

Real Costa will also have a warranty card with the pack where you can see all the information about the warranty for that specific model. Read more about their warranty.

3. Premium Lenses

Costa means advanced lenses and there are no lenses better than Costa in the current market. 

So you’ll not see any company that makes the same lenses as Costa, and this can be a great way to check whether your Costa sunglasses are real or fake. 

Wear sunglasses and feel the quality. You’ll see the color is enhanced and a better view around you.

Another direct sign of Costa sunglasses is the polarized lenses. As you may know , Costa only sells polarized lenses.

Costa uses multiple materials such as co-injected Nylon, Acetates, Metal, and Plastic. However, all of their frames are well-created. 

The frame will last for a long time as they are flexible and durable. So if you notice your already-having frame isn’t durable and flexible, you can assume that you’re having a fake Costa.

Costa ensures a smooth opening and closing feature with all of their sunglasses because the frame comes with flexible and smooth Spring Hinges that are carefully built. 

If you’re using sunglasses that make a breaking noise when opened, or you just feel something difficult when opening and closing the temple arms, assume that this sunglass isn’t from Costa.

6. Costa Should Be Expensive

Costa’s products are always expensive, and if you bought a sunglass at a cheap price, this would never and ever be Costa’s product. 

Visit the official store of Costa’s products on Amazon, and also check out Costa’s authentic site to check the price ranges.
