Description

Pupil distance adjustable glasses

Technical Field

The utility model relates to the technical field of glasses, in particular to a pair of pupil distance adjustable glasses.

Background

In the fitting and assembly of functional lenses, the single-sided interpupillary distance of the human eye relative to the center sill of the frame is an important personalized customization parameter. This is because functional lenses typically have a specific distribution of visual areas on them, and only if the human eye is matched to these distributions, the wearer can achieve the corresponding visual function and achieve a comfortable wearing experience. For example, a common functional lens, such as a progressive lens, is a high-precision free-form surface lens that satisfies both the far-vision and near-vision tasks of the wearer, and the surface of which can be divided into a plurality of functional areas (including a distance zone, a near zone, a channel zone, and a peripheral astigmatism zone). When the actual position of the human eye deviates left and right from the pupil reference point, the peripheral blind area is easy to see when the human eye rotates up and down, so that the discomfort of deformation of the visual object is felt. Thus, particularly in the prescription of progressive lenses, accurate acquisition of the interpupillary distance is required. In general, the individual's interpupillary distance varies from 4 to 10mm, and thus the same pair of eyeglasses may not be shared even if the vision correction prescriptions of two persons are the same.

In the prior art, most of the glasses are manufactured into finished products, and the positions of the lenses cannot be adjusted according to the interpupillary distance of the eyes of a user. Although a few glasses can adjust the positions of lenses according to the interpupillary distance of eyes of a user, for example, a pair of glasses with adjustable glasses frame spacing is disclosed in Chinese patent CN202020575234, and the glasses comprise a glasses frame, glasses legs, a nose bridge and lenses, wherein the nose bridge is composed of a main connecting sleeve and a slave connecting sleeve, the positions between the main connecting sleeve and the slave connecting sleeve are adjusted according to the width dimension of a face, and a butterfly connecting rod is used for fixing the main connecting sleeve and the slave connecting sleeve, so that the glasses adapt to different face dimensions. However, the glasses also change the overall width of the glasses frame when adjusting the positions of the lenses, namely the distance between the left and right glasses legs is changed, so that the stability of the wearer corresponding to the head circumference specification is affected. In addition, the glasses with the structure need to be taken off for operation when the positions are adjusted, so that the real-time adjustment and fastening are inconvenient when the glasses are worn, and the repeated taking-off and wearing adjustment process is troublesome.
