Description

A portable spectacle frame with adjustable interpupillary distance

technical field

The utility model relates to a spectacle frame, in particular to a portable spectacle frame with adjustable interpupillary distance.

Background technique

At present, there are many kinds of finished reading glasses on the market, such as folding frames and telescopic retracting frames. These designs are designed for the purpose of portability and storage. Difficulty using the eyes at close range. The finished presbyopic glasses meet the needs of middle-aged and elderly people, but they do not solve the comfort of seeing near. The reason is that the national standard of this type of product does not have strict requirements on the interpupillary distance. The required part is in the customized glasses, because The distance between the optical center of the lens and the distance between the wearer's pupils does not match, causing the wearer to experience discomfort such as visual fatigue, dry eyes, astringent eyes, and dizziness after using the finished reading glasses. After the pupil deviates from the optical center of the lens, the A prism effect is produced, so the above-mentioned discomfort will be produced.

In terms of sales price, because the price of finished reading glasses is very different from that of customized glasses, most people choose finished reading glasses in order to be cheap.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-8, a portable spectacle frame with adjustable interpupillary distance includes two frames 1, temples 3 and nose pads 2, the temples 3 are connected to the frame 1, and the nose pads 2 are fixed on the side of the frame 1. At the lower end, the two frames 1 are connected by a telescopic nose bridge 4, and a scale line 5 is arranged on the telescopic nose bridge 4. The mirror legs 3 are connected to the mirror frame 1 through a folding structure. A quarter of the mirror leg 3 is equipped with a fixed hinge, so that the mirror leg 3 can shrink, which is convenient for storage. The folding structure is a spring hinge. The telescopic nose bridge 4 includes a first fixed rod 6 , a second fixed rod 7 and a telescopic rod 8 . The first fixed rod 6 and the second fixed rod 7 are respectively fixed on the two picture frames 1, one end of the telescopic rod 8 is connected with the first fixed rod 6, and the other end is inserted into the second fixed rod 7; The scale line 5 described above is set on the telescopic rod 8, and there are 5 scale lines on the telescopic rod 8, marked with "0", "2", "4", "6", and "8", respectively representing the interpupillary distance 60, 62, 64, 66, 68. There are 5 screw positioning holes in the telescopic rod 8 rear sections, and the center-to-center distance of every 2 holes is 2 millimeters, respectively limit 68, 66, 64, 62, 60. The optical center of the eyeglass is exactly the geometric center of the picture frame. By shrinking the telescopic bridge of the nose 4, the distance between the geometric centers of the two eyeglasses is adjusted and controlled between 60-68 millimeters, and the telescopic rod and the second fixed rod 7 are drilled. A screw hole 9 is drilled at two millimeters, fixed by a nut 10, and selected according to the interpupillary distance of the wearer; preferably, the spring hinge includes a spring 11 and a fixed pin 12, and one end of the fixed pin 12 is fixed to the temple 3, The other end is inserted into the picture frame 1 , one end of the spring 11 is connected with the fixing pin 12 , and the other end is connected with the picture frame 1 .
