Polycarbonate is known to be a great material in the eyewear industry. Some companies use it to make lenses and even eyewear. But why do companies and store use Poly? Lets take a look at the pros and cons.....
PROS
-Bullet-proof: Well, that's what chain stores claim, but it's at a few inches thick that it is bullet-proof
CONS
-Scratches easily: Great for stores, because they have a repeat customer whether you like it or not.
-Poor vision: The material itself does not support great vision like other materials. It is basically the worst visually.
Why do all chain stores sell them?
-Liability: The lenses rarely break
-Scratches = repeat: they would love to see you back
In conclusion, the newer polycarbonate lenses are better than previous technology polycarbonate but still not as good as high index. BUT if you're looking for lenses for when you are out playing beach volleyball, you found a good product. If you are looking for something more than that, look into other materials. Don't let the chain store's advertising fool you into buying an inferior product. Be educated!

Who manufactures what?
There are several ways that companies and factories will manufacture frames. Let me take you through a few of the processes.
1. "Factory X" will see trends and start manufacturing models. Company B will buy the frames and stamp their names on it. Company C will stamp their name on it and sell it too.
2. Company ABC will buy the rights to a name like Prada. They will then have their "Company A designers" to design it and manufacture at "Factory Z". They will then distribute it and sell it. In this case, Prada actually has NONE of their own designers on the project. They may have a head designer that will give them the okay to produce it to their likings, but they will not deign it.
3. "Factory Z" will have models that they commonly make for companies like Company ABC. They will just sell the frames with a new name and there we have a "generic" frame with Prada styling. OR they will have left overs from a run that Company ABC made or their defects and then sell them to other companies. Voila the fake!
4. Then we have high end like "Designer 123". Designer 123 will design a nice model. He will then find a factory that has the machines and equipment to make it to his standards. He will then have sample made and see if they can create to his standards. If they are still to his standards, he will start production. Usually he will continue to maintain his standard by overviewing all the production.

How to Measure Frames
To CityConnection,
I just read your post about how to read the frames, but I can't really understand how to read the sizes. Am I supposed to just eyeball the dimensions by looking at the pictures of the frames? I want to know that they are rectangular as opposed to square-ish. How can I ask for more measurements?
Jon C.
I know what you mean. Let me explain the dimensions that we usually measure in the industry.
A= Horizontal length of lens
B=Vertical length of lens
ED (Effective diameter)= The longest radius from the center of the lens to the furthest point of the lens, and then multiplied by 2.
DBL= Bridge width
There are sometimes slight variations depending on whether or not you you include the inside of the frame to the measurement. But in general this is how we (and now, you) measure eyeglass frames.
