In most cases the Bifocal ADD should be the same as the normal prescription. However, some
surgeons prefer the ADD to be of a power that produces a working distance similar to that of the
loupe telescopes. This avoids constant accommodation as they alternatively look through the
loupe and alongside for orientation. Others prefer a weaker ADD for easier focussing onto surgical
instruments outside the operative area. Discuss this matter with your customer to ascertain which
option is best suited to their needs.
ALL lenses should be plastic
Once your customers loupes have been glazed, it may be necessary to place the loupes on the front
stop of the loupe pins to prevent the telescopes from touching the lenses, particularly where the
curvature of high powered lenses prevent the loupes from being angled fully downwards.
CORRECT FITTING OF
RIESTER
LOUPES
When you have glazed your customers correction into the loupe frame, we would be grateful if
you could offer further assistance to help them “set up” the loupes correctly so that they can
obtain the best from them. Full fitting instructions are given earlier.
