How do I utilize bifocals? Install bifocal lenses so that only the 

upper third is for distance and lower 

two-thirds is for reading. Adjust the 

nose bridge so that frame sits higher 

on nose. Then lower the height 

adjustment. This will ensure that

the binocular viewing system will 

be positioned in front of the reading 

part of the lenses.
