Many attemps were made, by many companies, some famous brands, some licensed replicas, but no one came close to replicate the exact look. Only Rodenstock came really close, but they discontinued their run many years ago. So we were left stranded, with no replicas to wear. Cheap knockoffs did make the trick for a while, but they had frames. We did NOT want frames!
So the choice was simple: I'm going to make my own, whatever it takes. I'm walking that path.
The first step was the design. Nobody really nailed the shape but Rodenstock, and I soon discovered why. The lenses look different depending on the angle you look at them, because they are bent in three different directions. So it was really difficult to nail the shape in every direction you look at them. But we suceed. We had a prototype.
Then I bought some virgin lenses and dremeled them by hand, until they were the exact shape we wanted them. On the first pair I ever built, I made the small holes for the temples and the nose bridge by hand, and then mounted everything together. I was very lucky they came out pretty decent, so I was happy for a while. That was circa 2008.  Time to upgrade. The first pair weared out 4 years later, and I had to start all over again. But I had the templates, so it was way faster this time.
I went to an optometrist, and asked him to drill the holes and bought some quality nose bridge, and titanium temples. Three days later, a PERFECT pair of NEO's sunglasses were mine. Finally.
They lasted 4 days. A gust of wind took them off my shirt, and they landed under a car's wheels.
Shit happens.
The third pair lasted 5 years, and I gave them to a friend. The next pair is the  ones you see in the pictures, here in this website, that's how sturdy and durable they are. You can see chips here and there if you look closely, but those sunglasses are 8 years old now, and I even stepped on them by accident once! Now that is quality building materials there.

So here they are, for you. A little pricey, but you'll have sunglasses for YEARS. 
A very well known Collector of MATRIX Sunglasses named these the BEST REPLICAS ever, or at least the best available.  See the video here. The first pair he holds and talks about, around 2min 44sec in, are mines. See how he explains the bending, and how accurate they look once they are bent to your face. Thanks Andrew.
Those are exactly the same pair you buy here. Same lenses, same nose bridge, same temples, same sunglasses.

Still here? What more do you need? Go grab a pair!

Thanks a lot for you trust in this product, you will not be disappointed. Take care!
