A method of manufacturing a three-dimensional lens comprises inputting a lens template into a controller, depositing a first layer of lens material onto a work surface according to the lens Template, and successively depositing additional filamentous layers of the lens material onto the first layer. The deposition of layers of lens material is done according to the lens template in order to build the three-dimensional lens with a particular transmission scattering profile for transmitted light.
