Some time ago you could see on this website two related videos ( How Glasses are Made & How Contact Lenses are Made ).
Today you can see another "How to" video, but a video that will blow you away.You will see how people in China can make some amazing sunglasses.Now we have factories that make this work but China is providing what every company is looking for "low cost manufacturing", that can maximize their profits.Now you can figure out how some people sell sunglasses just for $2.00.
The video doesn't have any sound, but it's quite self-explanatory.
