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.

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.
