Abstract
The optical design of biocular magnifiers at Pilkington PE Ltd is described with particular reference to the assessment of user visual comfort. The implementation of specialised computer software on a high speed computer dedicated to optical design calculation, has enabled accurate modelling of the visual image produced by very low relative aperture (f/0.6) magnifiers. Graphical output is discussed. The aberrations of the magnifier can be expressed in terms of visual effects and tolerances ascribed to define acceptable visual performance. The methods are applied to some new large diameter magnifiers for relaxed viewing.
