⭕ One VisiOffice by Essilor Optical System. The unit powers on and takes remarkably accurate measurements. This is a perfect working unit - we simply replaced ours with a brand new version.

Unit includes Manuals, power cable, unit cables (ie to connect the base to the measuring head and to the touchscreen/keyboard) and a measuring widget to apply to the eyewear.
