背景技术 Background technique

[0002] 众所周知,眼睛由眼球、视神经和视路、眼附属器三部分组成。 [0002] is well known, the eye consists of three parts of the eye, optic nerve and visual pathway, adnexal composition. 眼球包括眼球壁、眼内腔和内容物、神经、血管等组织,由外往里有角膜、巩膜、虹膜、睫状体和脉络膜、视网膜, 虹膜上附有瞳扩肌,中央为瞳孔,睫状体上有层悬韧带,又称睫状肌,眼内腔和内容物最重要的部件是晶状体,晶状体为富有弹性的透明体,形如双凸透镜,位于虹膜、瞳孔之后及玻璃体之前,在睫状肌作用下可以调整焦距,这种特点叫屈光特性。 Eye includes the eyeball wall, and lumen contents eye, nerves, blood vessels and other tissues, from the outside inwards cornea, sclera, iris, ciliary body and choroid, retina, pupil with muscle expansion, the center of the pupil iris, eyelashes shaped upper layer has a suspensory ligaments, also known as the ciliary muscle, the most important member and lumen contents are eye lens, the lens is flexible transparent body, shaped like a lenticular lens, an iris located before and after the pupil vitreous, in the focal length can be adjusted under the action of the ciliary muscles, which features an injustice optical properties. 眼附属器包括眼睑、结膜、 泪器、眼外肌和眼眶。 Adnexal includes eyelid, conjunctiva, lacrimal, extraocular muscles and eyes. 眼睑就是通常所说的眼皮。 Eyelid known as the eyelids. 眼外肌包括上直肌、下直肌、内直肌和外直肌、上斜肌和下斜肌。 Extraocular muscles including superior rectus, inferior rectus muscle, medial rectus muscle, and lateral rectus muscle, the oblique and inferior oblique. 眼眶由颅骨构成,呈稍向内,向上倾斜。 Orbital consists skull, showing the slightly upwardly inclined.

[0003] 综观眼睛结构和人体特征,人眼在长时间视物或观看位置不适当时都会产生视疲劳,一般来说,眼睛的视疲劳包括如下几个方面:眼睛的屈光度疲劳、肌状性疲劳、集合性疲劳、融合度疲劳、环境和视物产生的疲劳、以及人体健康因素产生的疲劳,其中屈光度疲劳占视疲劳的80%以上,资料表明:视物距离最小到25cm时人眼会产生屈光度调整,左右眼屈光不一致也会引起大脑中枢不适反应。 [0003] Looking at the structures of the eye and body characteristics, then the human eye will have a long time depending on the visual fatigue or discomfort viewing position, in general, visual fatigue to the eye include the following aspects: refractive eye fatigue, muscular fatigue resistance like , fatigue fatigue collective fatigue, degree of integration fatigue, environment and depending on the material produced, as well as human health factors of more than 80% of the diopter fatigue accounted visual fatigue, the data show that: the minimum visual distance to 25cm human eye will produce diopter adjustment, left and right eye centers in the brain can also lead to inconsistent refractive discomfort. 显然当人眼观看近的物体时,眼球晶状体收缩会引起屈光反应,同时由于物体拉近双眼的平行度改变,向物体中心方向汇聚集合从而双眼会产生集合性现象,瞳扩肌、眼外肌、睫状肌随大脑中枢电冲动作进行平衡调整会形成肌状性反应,当物体靠得太近,由于左右眼视像差相差太大时会引起大脑视区图像融合困难产生不适,还有环境的光线强弱、外界强的反射眩光、酸碱度、视物的清晰度以及人体健康好坏都会对人眼工作产生关联的影响,所以人眼视疲劳特征虽然特征独立但彼此有很大的关联性。 Obviously when an object near the human eye, the refractive lens of the eye can cause shrinkage reaction, and because the object change degree eyes closer parallel to the direction of the center of the object will have converged set of eyes so set phenomenon, pupil expansion muscle, extraocular muscle, ciliary brain with electrical impulses for central balance correcting muscle-like formation reaction, when the object is too close, the difference between the left and right eye video image fusion of the brain can cause difficulties in viewing zone when the difference is too large discomfort, further there are environmental light intensity, outside the strong reflected glare, clarity and pH of human health are good or bad, depending on the material of the impact on the human eye associated work, so as fatigue eye but which are characteristic features of the independent though great relevance.
