HC Deb 21 February 1922 vol 150 c1725
82. Mr. KILEY

asked the Financial Secretary to the Treasury why duty is collected under the Safeguarding of Industries Act on some kinds of spectacles and not on others; if this is on the ground of difference in magnification, does he work on some standard of definition; and, if so, will he state for the information of those concerned what standard it is?

Sir W. MITCH ELL-THOMSON

The answer to the first part of the question is that all spectacles fitted with lenses are liable to duty in respect of the lenses, and I am not aware of any cases in which duty has not been collected accordingly. The remainder of the question consequently does not arise.
