Distance vision-realizing eyeglasses for image display device

Abstract

The present invention relates to distance vision-realizing eyeglasses for an image display device, the eyeglasses having the purpose of relieving visual display terminal (VDT) syndrome by assisting inrelieving eye fatigue by enabling the realization of distance vision. The distance vision-realizing eyeglasses for an image display device, according to the present invention, enables the realizationof distance vision by using double convex lenses. Here, distance vision is realized by having, among the double convex lenses, an outer convex lens positioned on the outer side to be fixedly providedto a lens housing, and an inner convex lens positioned in the lens housing to be installed so as to be capable of forward / backward movement.

Description

technical field [0001] The present invention relates to spectacles for image display devices, and in more detail, relates to spectacles for displaying long-distance vision for image display devices that utilize double-convex lenses to realize long-distance vision and contribute to the recovery of eye fatigue. Background technique [0002] As the use of personal computers and smartphones increases, attention to Visual Display Terminal Syndrome (VDT syndrome) is also increasing. This VDT syndrome refers to ocular symptoms (eye fatigue, medial squint, etc.), skeletal / muscular symptoms (shoulder pain, low back pain, etc.) , Mental symptoms (unease, neurosis, insomnia, etc.) of health disorders. The U.S. legislated on VDT ​​work restrictions, Japan set up a VDT countermeasure committee under the government, and the Korean Ministry of Labor established the Industrial Accident Compensation Insurance Act, and added VDT syndrome to the list of work-related accidents that can enjoy p...

AI Technical Summary

Problems solved by technology

First of all, due to the use of a single lens to drive the performance of long-distance vision, the use of a single Newton lens to improve the effect of long-distance vision is limited

Second, since it has a structure that moves a pair of Newtonian lenses back and forth, impurities or dust may enter the eyes and the lens moving operation part

In addition, there is a structural disadvantage, that is, in order to move a pair of Newton lenses back and forth, in addition to the Newton lenses, it is also necessary to move the lens holder enclosing the Newton lenses at the same time.

Therefore, the center of gravity of the image display goggles changes greatly with the movement of the Newtonian lens, so the wearing experience of the image display goggles deteriorates

Also, in order to simultaneously move the frame surrounding the Newtonian lens, a large amount of power from the power source motor is required, and frictional vibration and noise may occur
