视力

The myth that eating carrot improved your eyesight was exploded years ago .

认为吃胡萝卜可以改善视力的海外奇谈，多年前已祛除殆尽。

Results The average onset age of moyamoya disease was very young. Female was dominant in our studied. Younger patients with moyamoya disease mainly suffered cerebral ischemia (87.5%). Adult patients suffered more cerebral hemorrhage (41.2%). Among clinical manifestations, headache, vertigo, paralysis, hemiplegia or alternative hemiplegia were common symptoms. Sometimes aphasia, dementia, visual acuity were decreasing, epilepsy and chorea minor might occur. 14 cases had received CT examination, but none was diagnosed moyamoya disease by CT. All patients received MRI and MRA examinations were diagnosed as moyatnoya disease.

结果 烟雾病发病平均年龄较轻，女性多于男性；少儿烟雾病患者以缺血改变为主(87.5%)，成年烟雾病患者缺血改变(58.8%)与出血改变(41.2%)相当；临床以头痛、头晕、肢体无力或偏瘫或交替性瘫痪为主要表现，同时可伴失语、智能下降、视力下降、癫痫发作、小舞蹈发作等表现。14例行头CT检查仅示颅内病灶，均未提示烟雾病；25例均行MRI和MRA检查发现颅内病灶，显示颈内动脉虹吸末段和大脑前或中动脉近段狭窄或闭塞，并有脑基底部异常血管网及侧支循环形成，均被诊断为烟雾病。

To enlarge the measurement range of a potential vision meter and improve its measurement accuracy for patients with high error of refraction, the imaging characteristics of its optical system were investigated. The visual magnification equation of the system was derived. The influence of the focal length variation of the collimating lens and the imaging lens on the magnification was analyzed respectively.

针对潜在视功能检测仪临床使用中量程有限和对高度屈光不正患者检测结果有一定误差的现象，研究了其光学系统成像特性，建立了系统对视力板成像的视觉放大率公式，分析了准直透镜、成像透镜焦距变化对视觉放大率的影响。

The focus of the collimating lens has effects on the slope of the visual magnification curve while the focus of the imaging lens affects visual magnification of the whole moving range in the same way.

系统中视力板移动检测时，准直透镜焦距影响视觉放大率变化快慢，决定视觉放大率曲线的平缓程度；成像透镜焦距对视觉放大率产生整体影响，使视觉放大率曲线产生整体平移。

The rate of hbv carriers reached 4.53%, and the color weakness rate was 1.73%.conclusion: the descending of eyesight, hbv carrying and color weakness are the main confinging factors for entrance exams.therefore, some countermeasures can be taken to reduce those unfavorable factors.

视力下降、乙肝病毒携带、色弱为主要限考因素，为减少这些情况可实行相应的健康对策。

Presbyopia light through the cornea and the lens, the focus will be gathered in the retina, can have a clear vision.

老花眼光线通过眼角膜与水晶体之后，能够将焦点聚集在视网膜上，才能有清晰的视力。

Lens fibers decomposed and dissolved in cream-white liquefaction, brown-yellow hard nuclear sank down, the anterior chamber in upper part became deep, called Morgagnian cataract.

晶体纤维分解液化，呈乳白色，棕黄色的晶体核沉于囊袋下方，可随体位变化而移动。称为Morgagnian白内障。当晶体核突然下沉后，视力可突然提高。

随着&独眼巨人&大锤的敲响，他来到火神赫斐斯托斯跟前。火神派向导带他去太阳升起的东方。将眼球暴露于阳光后，他就恢复了视力，成了女神阿尔特弥斯永久的伴侣，并带着他的猎狗天狼跟随女神打猎。阿波罗并不赞成他们之间这种恋情。一天，阿波罗怂恿阿尔特弥斯向海中一移动的黑点射箭。她根本没想到自己是将箭瞄准奥利安。当看清黑点竟是在游泳的恋人奥利安的头时，阿尔特弥斯悲痛万分。

他是海神波塞冬漂亮的儿子。一天，他在森林中打猎，看到了阿尔特弥斯的仙女们——七颗明星。他如此爱慕她们的美丽，便追赶她们。困境中，美貌的仙女们向阿尔特弥斯求救。结果女神将她们都送入天空充当星座。后来奥利安爱上了另一少女墨洛珀。他鲁莽急躁地施暴于她。这激怒了少女的父亲俄诺皮耳国王。国王把他灌醉后，挖出了他的眼睛。随着&独眼巨人&大锤的敲响，他来到火神赫斐斯托斯跟前。火神派向导带他去太阳升起的东方。将眼球暴露于阳光后，他就恢复了视力，成了女神阿尔特弥斯永久的伴侣，并带着他的猎狗天狼跟随女神打猎。阿波罗并不赞成他们之间这种恋情。一天，阿波罗怂恿阿尔特弥斯向海中一移动的黑点射箭。她根本没想到自己是将箭瞄准奥利安。当看清黑点竟是在游泳的恋人奥利安的头时，阿尔特弥斯悲痛万分。因她无力使他起死回生，只好将他送入天空作一星座。他的猎狗天狼则蹲在他的身旁。
