By investigating the near interpupillary distance of adults and the parameters of near-vision spectacles on the market, according to the tolerance error range of the national standard, the relationship between the near-vision spectacles and the near interpupillary distance error can be obtained. The results show that the average value of the nominal optical center horizontal distance of near-vision spectacles is about 62 mm. These results match the actual near interpupillary distanceof the male wearer. However, it cannot match the interpupillary distance of women or consumers who require high vertex power for presbyopia. It is recommended that the manufacturer should design the optical center horizontal distance of the near-vision spectacles with reference to the average value of the near interpupillary distance.
