Abstract
DURING recent years, renewed and increasing interest has been shown in the use of aspherical surfaces as a means of improving the performance of optical instruments, and one notable application has been to low-power singlet lenses for industrial inspestion purposes. Nevertheless, to the best of our knowledge, no serious attempt has hitherto been made to correct these lenses for binocular vision, and as a result of extensive experiments in this connexion it is now clear that a major contribution to the comfort of the user of such lenses over prolonged periods can be made by designing primarily for binocular viewing. It is proposed to publish a more detailed account of this investigation elsewhere; but in the meantime some notes on the more important features of the design may be of interest.
