摘要

[challenge] the position of the distance eye point and the near eye point simple, inexpensive, and, to provide a progressive glasses designed for sheet mask measurement jig that can be measured with high accuracy. on the front of the A binocular each dummy lens of containing glasses frame dummy lens, and measuring the position of the paste far-eye point to the eye point for near binocular pair of sheet mask 330 and a sheet mask measurement fixture 300 for progressive spectacle design to be used for. Located on the upper side of the sheet mask, a single horizontal reference line 30 of the height and of the binocular pair of matching distance eye point, since it is located in the middle of the sheet mask to measure the respective both eyes of one eye pupil distance Different plural vertical reference line 31-34 binocular pair made up of colors, because positioned below the sheet mask to measure the vertical distance from the distant eye point to the near eye point I and a plurality of horizontal reference lines 35-38 of different binocular pair made up of colors.BACKGROUND 5
