§ Mrs. Wiseasked the Secretary of State for Social Services if he will add a spectacle frame made of nylon to the range of children's National Health Service frames in the light of the greater strength and serviceability of this material for children's frames.
§ Mr. MoyleI understand that the industry has in the past tried nylon for making spectacle frames but found no significant advantages to outweigh the technical and manufacturing difficulties. In the circumstances I could not justify the extra cost of making NHS children's frames in nylon.
