Senator SENIOR (South Australia) . - It is evident that the fusing of two pieces of glass involves the use of different grades of material, otherwise we would not obtain the power of vision by means of a bifocal lens. The fusing is not a difficult process, but it would be unfair to import bifocal lenses. The sub-item reads, "bifocal lenses, partly or wholly finished," and, as labour may be cheaper abroad, users might obtain the lenses wholly finished, because the cost would not be so great. By making what follows " bifocal lenses " a separate item the position would be met, because we would then be protecting the work of grinding, which is done here. The fusing of lenses, which is based on opticians' prescriptions, can be done quite easily, and the work then given to the grinder. The grinding work would then be protected by a higher duty than was imposed on the blank or fused lenses.
