Adjusting for User Refractive Error

(Spectacle Models Only)
The optimal working distance from the object is 15" (38.1 cm) -
17" (43.2 cm). 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 eyecare practitioner of your choice. Please
bring the following information to assist your eyecare practitioner
in fitting your prescription lenses.
