Description
Technical Field
The utility model relates to the technical field of ophthalmologic instruments, in particular to a frame glasses try-on frame for acquiring parameters of a frame glasses supporting part.
Background
The prescription is processed into glasses meeting the national standard (GB13511-2011 & ltEquipped glasses & gt, hereinafter referred to as 'national standard') according to the requirements provided by the prescription. Since the state manages the production license of the processed glasses products, the hardware and software of the glasses manufacturing and assembling industry are continuously improved, and it is not difficult to assemble a pair of glasses with qualified quality according to the prescription. The prior prescription of single-lens glasses only marks four parameters of a sphere lens, a column lens, an axis and a pupil distance, and does not contain parameters such as a nose support of a glasses frame, a bending point of a glasses leg and the like which determine the relative position and stability of an optical center and a pupil of the glasses. On one hand, the deviation between the optical center and the pupil of the processed glasses is not ensured to be smaller than the national standard when the glasses are worn statically; on the other hand, the deviation between the optical center and the pupil is aggravated because the spectacle frame cannot be deviated after being worn dynamically.
The existing solution is to let the patient manually measure the height of the pupil or take a picture to record the relative position of the pupil and the frame after wearing the glasses which are actually purchased, and transmit the data to a processing workshop to ensure that the deviation between the optical center and the visual axis meets the national standard requirements, but the method can only solve the problem in the static wearing environment, but cannot solve the deviation caused by the unstable dynamic wearing. The problem of dynamic wearing stability can be solved by increasing the inventory of the spectacle frames with different sizes and enabling a patient to find the spectacle frame with the best stability by a physical try-on method, but the dynamic wearing stability is difficult to develop in practice due to the increase of the inventory cost of stores.
