Description
Technical field
The present invention relates to medical instruments field, especially relate to a kind of vision health monitor.
Background technology
Myopia is now all fairly popular in the whole world, and according to the authority's statistics having shutting mechanism, China's myopia of student incidence rate, up to 60%, occupies the first in the world, and Europe is 40% myopia, and the U.S. then reaches 41%.China has more than 400,000,000 myopes; especially in recent years the morbidity crowd of myopia constantly tended to becoming younger; but wherein the myope of 92% is not Familial Occurrence myopia; that is be major part myope pathogenic factor be all the unhealthy eye day after tomorrow, at ordinary times live in do not protect eyes.
Myopia is caused by axis oculi extends, and general alleged myopia belongs to retractive myopia.Retractive myopia eye spindle length is within normal range, and changed caused myopia by dioptric factors such as crystalline lenses, its essence is the effect emphasizing environmental factors, as treated not in time, the not only approximate number of degrees can constantly be deepened, eventually becoming true property high myopia, this not only will have a strong impact on child's physical and mental health, and select specialty and following employment to have considerable restraint when child enters a higher school.Modern medicine is it has been proved that the myopia obtained due to acquired disposition is as treated not in time also by heredity offspring.
In daily life, typical bad eye custom has and sees that TV or computer screen, closely read-write or light are not and excessively strong etc. for a long time, these can result in eyes muscular fatigue, time length can cause that eyeball back/forth diameter increases, it is difficult to shorten again once eyeball back/forth diameter increases, retractive myopia just develops into true myopia, and the treatment to true myopia is at all helpless.As can be seen here, the prevention of myopia is more important than treatment, and the generation of myopia can be fundamentally stopped in prevention.
At present, pre-myopic-preventing method is broadly divided into physicsl correct and chemicals two class: the method for physicsl correct is by drawing the distance forcing the objects such as fixed value health and books, physicsl correct mainly has two shortcomings, one is that to wear process loaded down with trivial details and carry inconvenience, and two is wear process inevitably cause uncomfortable on health or take action limited.And majority Applied Physics is corrected pre-myopic-preventing product and can only be controlled the distance of eyes and object, it is impossible to control illuminance simultaneously.
Physicsl correct method is not particularly suitable for teenager, because pull rope is if it is desired to the health of child must be applied certain counteracting force by the purpose reaching to correct, can cause the pain of the health of child, thus causing child's conflict at heart to apparatus for correcting.The more important thing is that adolescence body development is also incomplete, the binding force size of traction restraint device adjusts improper the blood circulation even growth of skeleton that will certainly affect child.
