§ Mr. David MarshallTo ask the Secretary of State for Health what information he has on whether the use of an auto-refractor and an auto-optitester provides a suitable and accurate sight test for people with less than perfect vision.
§ Mr. MellorAuto-refractors and auto-optitesters provide reasonably accurate information on the lenses patients may require to correct their sight. These instruments cannot, however, carry out examinations for injury or disease which form an important part of every sight test.
