Range Of Measurement:
Myopia
0 to -19.00 diopter in 0.25 diopter step
Hyperopia
0 to +16.75 diopter in 0.25 diopter step
Astigmatism
0 to -6.00 diopter(-8.00 diopter) in 0.25 diopter step
Phoria and vergency
20 to 0 to 20 by 1 step;Inner 40;Outer 40(50);Upward anddownward 40(46)
Near vision test
Main optical axes of both lenses converges by means of a tilt mechanismat 40cm in front of the eyes at 64mm P.D. If P.D. for far vision is less then54mm,converging operation stops.
Pupillary Distance
48 to 75mm by 1mm step
Binocular balance test
Rotary prism and polarizing lens methods are available.
