The process of lathe cutting starts with the small disks of raw plastic material which are placed on a rotating shaft. The shaft spins the plastic material at a high velocity while automated tools carve out the shape of the lenses. Once the shape of the lens has been made, the lenses are polished and hydrated in order to arrive at the soft.
