Technical field

This utility model is related to the glasses for correcting faulty sitting posture, and in particular to head position mistake when one kind can prevent from writing and/or reading The sitting posture glasses of part deflection.

Background technology

It is well known that students in middle and primary schools' Shortsightedness prevalence more and more higher, such case is serious all the more in big city.According to statistics Pupil's Shortsightedness prevalence even as high as more than 50%.Go out as myopia progression is susceptible to eye ground up to after certain altitude Blood, disengaging and cause it is blind, prevention and control students in middle and primary schools' myopia be the whole society concern key subjects.

When Germany professor first confirms that " seeing near " by primate model, the rear out of focus formed in peripheral retina is existing As inducible axis oculi is elongated, often long 1mm is near-sighted equivalent to increasing by 300 degree.Eye and watched attentively between object (such as desktop) when seeing near Distance it is nearer, after the peripheral retina of formation, out of focus phenomenon is more serious, induce myopia occur probability it is bigger.

It is reported that nearly 10 years, middle mountain Eye Center joint Australia, the institute of myopia research institution of Duo Suo universities of the U.S. The a large amount of animal experiments for doing also demonstrate that " seeing near " is the main inducing of acquired myopia.Therefore, limit students in middle and primary schools' reading, write The too near such as inclined head of gaze distance during word is watched attentively or is too near to and writes under the watching attentively of desktop, reads a book, after being prevention and control students in middle and primary schools The effective ways of nature myopia.

Popular restriction in the market sees that nearly method has various, main limited nearly jaw support, the nearly appearance alarm of supra-aural, volume Shell type sitting position corrector, tablet-style sitting position corrector, five class of support picture frame type.The leading edge that nearly jaw support need to be installed in desk is limited, User need to be placed on lower jaw in jaw support, have the disadvantage to need the normal loading, unloading shelfs of Jing.But the said goods have different degrees of lacking Fall into：
