    What’s the advantage to choose liquid silicone to make optical lenses?

    Comparing to Plastic, the properties of light transmittance, anti-yellowing and weathering resistance are better. Comparing to Glass, the optical liquid silicone is easy to shape, the fluidity makes the complex or micro-structure designs moldable.
