(Spectacle Models Only)

The optimal working distance from the object is 15" (38.1cm) - 17" (43.2cm). If this

model is used without corrective lenses and user is myopic or hyperopic, then the

user will need to work closer or farther from object, depending on refractive error.

To compensate for this, the spectacle models can be fitted with corrective lenses by an e

yecare practitioner of your choice.

Please bring the following information to assist your ey

ecare practitioner in fitting your prescription lenses.
