Pupil distance adjustable glasses

Abstract

Provided is pupil distance adjustable glasses. The glasses include lenses, temple bars, nose brackets, connecting pile heads, lens frames and lens brackets, slide bars are disposed transversely on theleft and right sides of the bottom ends of the lens brackets, two lens frames are arranged, two lenses are respectively mounted in the two lens frames, sliding slots are respectively formed in the upper ends of the two lens frames, the transversely distributed sliding bars on the left and right portions of the lower ends of the lens brackets are respectively sleeved with the sliding slots of theupper ends of the two lens frames, the ends of the two connecting pile heads are respectively mounted on the left and right side ends of the lens brackets, the front ends of the two temple bars are respectively hinged and mounted on the other ends of the two connecting pile heads, and the upper ends of the nose brackets are installed in the middles of the rear side ends of the lens brackets. According to the glasses, the distance (that is, pupil distance) between the two lenses mounted on the two lens frames can be conveniently adjusted, and it is ensured that the pupil distance of the glassesand the pupil distance of a person are in an excellent matching state so that the glasses can achieve the best use effect. Based on the above, the glasses have a good application prospect.

Description

technical field [0001] The present invention relates to the field of spectacles, in particular to an adjustable distance spectacles. Background technique [0002] Glasses can bring convenience to people with poor eyesight in use, so they are widely used. The interpupillary distance of the glasses, in short, is the distance between the optical centers of the two lenses. After wearing glasses, the foundation of normal vision can be achieved. If the interpupillary distance of the glasses is not adjusted well, after the user wears the glasses, the interpupillary distance of the glasses and the interpupillary distance of the eyes will not match, which will cause the wearer to experience dizziness, vertigo and other discomforts, and the prism effect of the lens will cause the wearer Eye muscles and vision are prone to fatigue and damage the health of the wearer. However, most of the presbyopic glasses sold on the market are finished presbyopia, that is, glasses that have been e...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the disadvantages of the existing glasses that the lenses cannot move left and right along the frames respectively, and the interpupillary distance cannot be effectively adjusted, which brings inconvenience to the wearer. There is a sliding rod horizontally distributed on the left and right sides of the lower end of the frame, a straight tooth is distributed horizontally on the front and rear sides of the inner upper end of each chute, and a straight tooth is horizontally distributed on the front and rear sides of the lower part of the left and right sliding rods of the frame. Straight teeth, the left and right ends of the slide rod at the lower end of the frame are respectively set in the upper chute of the two lens frames, the two straight teeth are tightly meshed, and there is a horizontal indicator at the rear end of the two lens frame chute Scale, there is an inverted triangle indicator mark in the middle of the left and right rear sides of the frame. In actual use, the chute at the upper end of the two lens frames is located under the left and right slide bars at the lower end of the frame for convenient left and right adjustment. Adjustable distance glasses can achieve the purpose of adjusting the interpupillary distance of the two lenses, thereby ensuring that the interpupillary distance of the glasses and the interpupillary distance of the human eye are in an excellent coincidence state, allowing the glasses to achieve the best use effect.
