Frame glasses adaptability detection and evaluation method

Abstract

The invention discloses a frame glasses adaptability detection and evaluation method, which is designed for detecting and evaluating the adaptability effect of frame glasses and the head and face partof a person needing a pair of glasses in real time. The method is characterized in that a coordinate point and a displacement measurement point are respectively arranged on the adaptive frame glassesand the head and face skin of the person needing a pair of glasses; after the person needing a pair of glasses does habitual activities, offset data of each measuring point is read; the offset data and optometry data of the person needing a pair of glasses are jointly substituted into a mathematical model for operation; the adaptability is comprehensively evaluated. The method belongs to initiative application to the technical field of visual optics glasses dispensing science, breaks through a frame glasses adaptability effect evaluation technology, and provides an important theoretical verification and judgment basis and operation flow process for building followable, objective and consistent glasses dispensing evaluation standards; important contribution is made in aspects of protectingthe human visual development and improving the visual function. The method has the advantages that the technology is scientific; the measurement is precise; the operation is convenient; the method issuitable for comprehensive detection and evaluation on the adaptability with the head and face of the person needing a pair of glasses in different environments; through the application, the occurrence of conditions of glasses incompatibility can be greatly reduced; social benefits and economic benefits are great.

Description

technical field [0001] The invention relates to a method for detecting and evaluating the adaptability of frame glasses, which is suitable for real-time detecting and evaluating the adaptability of frame glasses and the head and face of a wearer. Background technique [0002] Glasses are a special medical device for correcting eyeball refraction, protecting eye health and improving visual function, and are important optical correction tools in optometry. At present, the production of glasses is carried out in accordance with the national standard for fitting glasses (GB10810.1-2005 "Spectacle Lenses", GB / T14214-2003 "Spectacle Frames" and GB13511-1999 "Fitting Spectacles"). In the current spectacles dispensing process, there is a widespread problem that has not been paid enough attention to, that is, the incompatibility between the frame glasses and the optician. The main reason is that the contact support of the glasses on the head and face of the wearer deviates from the ...

Problems solved by technology

The main reason is that the contact support of the glasses on the head and face of the wearer deviates from the ideal theoretical glasses support design, and the instability of the glasses support will cause the optical center of the glasses lens to deviate from the pupil, thereby affecting the visual effect of the glasses; The fitting of glasses is mainly carried out according to the diopter, left eye interpupillary distance, right eye interpupillary distance, left eye pupil height and right eye pupil height in the optometry prescription. However, practice has proved that these data cannot effectively guarantee fitting The use effect of the glasses is difficult to satisfy the good match between the glasses and the wearer's head and face, and can only be adjusted manually by relying on the subjective feelings of the optometrist and the wearer

At present, although various adjustable glasses continue to come out, there is still no objective and unified standard for evaluating the actual fitting effect of the glasses, and there is no detection method for the stability of the contact between the frame glasses and the wearer's head and face
