§ Mr. Cormackasked the Secretary of State for Social Services what percentage of optical prescriptions issued during 1981 was for simple magnifying lenses.
§ Mr. Geoffrey FinsbergI am advised that single-vision lenses in positive spherical powers of 2.25 to 4.00 dioptres, which might be considered to be simple magnifying lenses, constituted approximately 10 per cent. of all lenses dispensed under the general ophthalmic services in 1981.
