Bifocal and Trifocal Lens Measurement

Bifocal lenses (or trifocal lenses) can be measured successively in the order of distance portion

*1

 near portion

*2

 (for trifocal lenses, distance portion

*1

 

 intermediate portion

*2

 

 near por-

tion

*3

).

Above lenses are measured on the auto measurement screen or normal measurement screen.

1 

Specify the lens side if necessary.

Press the R/L measurement select button 

 to switch to

 or 

.

The selected button blinks in green to indicate that
