Pupil distance adjustable portable spectacle frame

Technical Field

The utility model relates to an adjustable interpupillary distance's spectacle frame technical field specifically is an adjustable interpupillary distance's portable spectacle frame.

Background

The interpupillary distance is simply the distance between pupils, the two eyes of a normal person watch the same object, the object images at the retinas of the two eyes respectively and is overlapped at the visual centers of the brain to form a complete single object with three-dimensional effect, the function is called as binocular single vision, however, an infant is easily influenced by external factors in the process of forming binocular single vision, so that one eye watches a target, the other eye deflects and cannot look at the same target, so that strabismus is generated, eyeballs watch the object obliquely inwards in medicine, namely, the eyeballs are called as inward inclination, namely, commonly called 'chicken eyes', when wearing glasses, the interpupillary distance needs to be measured, and the interpupillary distance is divided into a far interpupillary distance, a near interpupillary distance and a common interpupillary distance. When the three interpupillary distances are measured according to a certain distance, when the spectacles are matched for patients with myopia or hyperopia, the parameter needs to be considered, namely, the distance between the centers of the two lenses (optical center distance) is matched with the interpupillary distance of the patient, otherwise, even if the degree of the lens is correct, the patient can feel uncomfortable after wearing the spectacles, and the vision is affected.

With the improvement of working requirements, living standards and aesthetic value of people, the glasses become an indispensable auxiliary tool for most people; the interpupillary distance of an adult is generally unchanged unless lesions or other external factors are present. The interpupillary distance of minors changes with age. The interpupillary distance is generally fixed after the age of 18 years, and slightly increased with the increase of the head bag before the age of 18 years; if the interpupillary distance changes, the glasses are not replaced timely, the eyes of people are damaged, and when the interpupillary distance of people changes, the glasses are adjusted quickly to adapt to the change of the interpupillary distance of people, so that a portable glasses frame with the adjustable interpupillary distance is needed.
