Description
Technical field
The present invention relates to a kind of study article field more particularly to a kind of Novel posture-correcting eye protective desks.
Background technology
Former students of nation myopic eye preventing and treating working group group leader Xu Guang chief editors'《Ophthalmology dioptrics》In explicitly point out：Cause
It is main cause that, which there are two big factor of h and E, the environmental factors such as myopia exercise in the reason of myopia,；
Student's learning tasks weight and pressure at this stage causes greatly most student's ultra-long time close eye even because of automatic control
Can the equal wrong read-write sitting posture that writes on all fours that occurs plus the carelessness of parent of force difference, sighting distance be 20 centimetres or even shorter super close
Distance eye lacks injury etc. of the electronic products such as exercise and mobile phone to eyes.Because reading study is full of entire teenager
Period reduces to the greatest extent so sitting correction set read-write is seen, forms sighting distance behavioural habits remote as possible when culture study in learning life
See immediate cause element especially cross short distance operation be adolescent myopia prevention and control main task, while reinforce physical exercise spy
It is not that outdoor exercise and control use electronic product etc.；
Desk and chair is the most important study article of teenager in learning life, its design is no rationally to cultivate with functionality
Very important effect is played during teen-age good learning posture custom.And the study table of school is most now
The table plane for being level altitude is rectangular conventional tables, and the effect of prevention and control myopia is insignificant.
Invention content
The purpose of the present invention is to provide one kind capable of adjusting different height, adapts to different crowd, being capable of specification study appearance
Gesture, effectively prevents crookback, preventing spine bending, and multi-angle desktop meets the Novel posture-correcting eye protective desk of a variety of learning demands.
The present invention is realized by following measure：
