The video was really interesting. I didn´t know there were people whose work is make artificial eyes! It´s amazing how real they seem to be. It´s actually a very meticulous work which requires a good hand, specific tools and machines as well as an oven set it in a certain temperature. It is a really complex process that has wonderful results at the end. What is really curious is the big amount of eyes they have to make every year. In addition, they look after fourty thousands patients who need these artificial eyes!. Finally, the expected life of an eye is around six years.
