6.4 Test of Far Vision and Near Vision
 There are two vision such as Far vision and Near vision. Generally, vision means Far vision,
and actually this manual also treats Far vision test throughout the most part. However, as the
problems of Near vision are growing recently, UDR-800P serves both Far vision and Near vision.
 To do Near vision test, change the mode by pressing [FAR/NEAR] button on touch screen, or
adjust Addition only, while maintaining Far vision mode by pressing [ADD] button. If a patient
has even presbyopia with nearsightedness(myopia), it’s recommended to test on [ADD] mode
by pressing [ADD] button.
 On each method, the Ref. Body of UDR-800P is tilted to the opposite side of the patient, and
input the information about the work distance and the patient’s age for an accurate test when
you do Near vision test.
