Description

The method of relieving visual fatigue on viewing display screen

The present invention relates to a kind of apparent equipment of viewing screen of eliminating and cause asthenopic method, is can eliminate because of watching televisor and computing machine to cause asthenopic method specifically.

At present, screen such as televisor and computing machine shows product to be used very widely, but watch televisor and computing machine to cause asthenopia for a long time, and then eye illnesses such as the initiation myopia or the blurring of image, become entire society is concerned about and insoluble problem very much, particularly bigger to teen-age harm, the school and the head of a family are an anxious not exhibition to this.Though release multiple sight protection instrument on the domestic and international market, wherein be no lack of the product that better curative effect is arranged, as No. 89215236.2 sight protection instrument of Chinese patent of Shanghai institute of physiology of Chinese Academy of Sciences invention, be representational in this class.It is introduced and not only can eliminate asthenopia effectively, and be particularly suitable for the treatment of teenage pseudomyopia.This product is to utilize optical principle,, seems from remote at the moment by the eyesight illusion the little picture of a width of cloth moving forward and backward among a small circle (several centimeters distances) with convex lens, light source etc., again from the moment to the remote picture that moves repeatedly.Make that the nearly thing of beholder is stared, distant view is looked into the distance, eyes do clocklike to come and go the focal adjustment activity, scientifically temper eye ciliary muscle and internal rectus muscle, reach to improve and regulate asthenopic purpose.The effect of this series products at home and abroad all goes down.For example the Wang Fang of Shanghai Medical Univ moistens " myopia " book (in September, 96, Shanghai Medical Univ published) of writing, has affirmed that in " ciliary muscle exercise method " the said goods is to eliminating the effect of asthenopia and treatment pseudo-myopia.But above-mentioned sight protection instrument is an independent instrument, uses the restriction of the subjective initiative that is subjected to time, environment and people, is difficult to adhere in time and frequently use, and the people's who watches televisor and computing machine asthenopia can not in time be eliminated.

The objective of the invention is to make this class screen of televisor and computing machine to show equipment and both had the function of viewing and admiring program, reading data, also in watching process, can in time eliminate asthenopia simultaneously.

The object of the present invention is achieved like this: at first, we are called the sight reading image to the image of viewing and admiring program or reading data and providing.This class screen of televisor and computing machine shows equipment, and what just often play is to see reading image.For making the beholder eliminate visual fatigue, we utilize screen to show the advantage of equipment, show a kind of image of simulation on the device at screen, and the picture of this image moves repeatedly, and is provided with a more suitable moving period from the near to the remote with by as far as closely.Like this,, watch the distance of this image to move to make equally a ciliary muscle adjusted and take exercise, and look health-care appliance is the same to have an asthenopic function of elimination as long as the beholder shows device not too (panel is bigger) far away from screen.At this, we this to eyesight with health role look the health care image by being called as far as colour near and that move by some cycles repeatedly from the near to the remote or black and white screen (containing object, sighting target).For the beholder who makes screen show equipment can eliminate asthenopia, the gap that utilizes broadcast program is by manual control or preestablish the time by the time principle and intercut to see in the reading image and play several minutes looking the health care image, reaches and eliminates and regulate asthenopic purpose.Now, the development of electronics and digital technology is as popularizing of large scale memory circuit, image processing techniques, high multiple electronic viewfinder and large-screen color TV etc., for the realization of this method provides assurance.Utilize memory storage to count width of cloth picture and picture is amplified or the processing dwindled can be accomplished.Utilize the emulation level of looking health care figure of the simulation of hyundai electronics and digital technology making, the quantity of the interest of image, image storage and the interchangeability of image can surpass the above-mentioned image that health-care appliance produces of looking.In above-mentioned screen shows equipment, devices such as storer and image processor are set, have constituted and looked the health care image source.This is looked the health care image source and can store in advance when producing, and also can handle forming again through image processor from seeing random acquisition on the interpreting blueprints image source.Image process method is that the image average rate is amplified, and average rate withdrawal former state is slowly shifting near and slowly leaving away for the image of feeling of human eye again.

Adopt the advantage of said method to be: can make this class screen of televisor and computing machine show equipment and not only have the conventional function of viewing and admiring program or reading data, and possess the asthenopic function of elimination.Make this class screen of televisor and computing machine show equipment and aspect vision protection, might become environment-friendly products.

Below in conjunction with accompanying drawing and present embodiment invention is described further:

Fig. 1 is the theory diagram of the embodiment of the invention.
