If you have bought a pair of Costa Sunglasses from someone other than Costa, you may wonder "are your Costa sunglasses real". When purchasing a pair of Costas you want to make sure you enjoy their premiere 580 technology. Therefore, you want to make sure to follow along to find out how you can be confident about the legitimacy of your pair of Costa Sunglasses.
How to verify the authenticity of your Costa Sunglasses
The main way to verify if your Costa Sunglasses are real is by looking for etching on the top right corner. Depending on the lens you bought, different etchings will appear.
580P Polycarbonate Costa Sunglasses
Costa polycarbonate lenses with 580 technology will have a 580P etched on the top left of the lens to demonstrate it's authenticity.

Prescription Costa Sunglasses
If your Costa pair has a prescription on them, a Costa logo will show before the 580 or a C followed by the 580 on different models.

All Costa Lenses are Polarized
On top of that, all Costa Sunglasses are polarized. Costa has established themselves as a premium polarized company with their 580 lens technology. Each Costa sunglass will have a polarized coating embedded in the lenses. Costa's 580 goes beyond polarization. Costa's lenses will filter out the harsh yellow light and filter out the bad HEV blue light. Essentially if you have authentic Costa sunglasses with the 580 etched in the top right lens, your eyes will always be protected. Also, Costa offers 7 different signature lens tints. Check out the diagram below to see how Costa 580 lenses differentiate themselves from other sunglass brands.

I bought a pair of costas about 1 year ago "tuna alley T39" at nordstrom rack the lenses dont have any kind of markings only the frames. I went to sell them and they been returned twice because the lenses are not real( thats what people that return them said) but they were purchased at nordstrom rack. Ive notice that all from nordstrom dont have markings on lenses. can you help me out with this. thanks
PS best sunglasses in the world thank you
It is possible Nordstrom only had Costa sunglasses with the 400 lenses, not 580 lenses. The old Costa 400 lenses did not have any markings on the lenses as you are describing. The 400 lenses were discontinued about a year or two ago. We only sell authentic Costa sunglasses with the 580 lenses that have the marking on them. Give us a call at 888-831-5817 and we can help you get some real Costa sunglasses with the 580 technology.
We just got word back from our friends at Costa that back in the earlier days they use to etch "Costa" in the right lens. They no longer do this but we can confirm you have authentic Costa sunglasses. As for the specific Tuna Alley frame you have, I'd recommend sending in a picture of the model to our optician team here They will be able to identify the specific colorway you have and any other question.
I hope you have a great day!
The Costa Double Haul is an older model that was discontinued a few years ago. It is possible the Double Haul has the Costa 400 lenses that did not have any etching on it. I hope this helps answers your question. Please feel free to contact us at www.sportrx.com/contact if you have any more questions.
Our team of opticians should be able to help with that. You can send a picture of the Costa sunglasses you have here https://www.sportrx.com/contact. They will respond quickly and help answer any other question you may have. Thank you for reaching out!

Our friends at Costa confirmed the Reefton was released in 2016, which is when they still were etching Costa into the right lens. However, since then all Costa Reeftons will only have either 580P or just 580 etched into the lens. It is possible whoever gifted them to you had one of the early Reeftons from 2016. But if they were purchased recently they should only have 580P or 580 on the lenses. If you are not sure please feel free to email me a picture at ryan@sportrx.com and ill help confirm if you have authentic Costa sunglasses. Thank you for reaching out!
If you take a few pictures of your frames from various angles and one that includes the info on the inside arm, and send them to info@sportrx.com one of our licensed opticians will get back to you in no time with confirmation of their authenticity.
