IV. DEVICE

1. General description of product
This device aims to take the measurements of SPH, CYL, AXIS, prism refractive power and optical axis
coordinate of unprocessed lens, processed eyeglass lens and contact lens, and to put dots on them to find its
axis.
It also performs automatic discrimination of progressive lens, pupillary distance (PD) measurement of glass lens,
UV cut percentage measurement, blue light which harmful to eyes cut percentage measurement, blue light
transmittance measurement which necessary to adjust the circadian rhythm.
Refer to [Instructions for use] about the operating precautions of this device.
The interval from -5D to + 4D covers 97% of the glasses used.
Performance is optimized for use in a room lit between 300 to 1000 Lux.
The performances of the BV (Blue Violet) and CB (Circadian Blue) measurements are:
Repeatability: <1% (for -5D to + 4D, or 97% of the lenses)
Reproducibility: <3% (for -5D to + 4D, or 97% of the lenses)
Precision: < 5% (flat lenses)
Precision: <7% (for -5D to + 4D, i.e. 97% of lenses)
2. Parts identification
