    Sometimes, it is really hard to tell whether the lenses of your glasses are polycarbonate ones or plastic ones. And usually, people tend to have a comparing about the weights of their glasses and then tell whether they are polycarbonate ones or plastic ones. And then get a result that the lighter ones are polycaebonate ones. That is sure a way. I do not know who tell you that polycarbonate lenses are thinner than plastic ones, but that is out of my knowledge, because what I know is that polycarbonate lenses are thicker than plastic ones. The reason is also very simple. Because polycarbonate is a mixture of high-molecular compound, and so it has different melting points and high light transmittance, which is much higher than plastic. And the light transmittance of a material decides the thickness of the lenses. So that is why plastic lenses should be thinner than the polycarbonate ones.

    Yes, polycarbonate lenses are thinner than plastic because of the material. A lot of people choose the eyeglasses with polycarbonate lenses to make them feel light at the weight. They will look so comfortable. You could just go to the online store to buy the polycarbonate lenses with suitable price. The price in the online store is suitable.

    Yes, polycarbonate lenses are generally thinner than plastic. That is because polycarbonate lenses are made of polycarbonate material which is high polymer and has high density. What's more, polycarbonate lenses are made by heating the polycarbonate particle and reshape in high temperature. While normal plastic lenses are made by grinding and cutting a piece of plastic plate.
