您要查找的是不是:
- distant vision test chart 远视力表
- Your distant vision is only 0. 2. Now come and have a look at this chart for the near vision. 您的远视力只有0.;2,再查一下近视力,请看这张表。
- vision test chart 视力表
- Having one section that corrects for distant vision and another that corrects for near vision, as an eyeglass lens. 双光的一个矫正远视而另一个矫正近视的,如眼镜
- When the cornea curves or flattens unevenly, the result is astigmatism, which disrupts focus of near and distant vision. 散光是当角膜变弯或者变平时表面不平坦,影响视近、视远时的聚焦。
- Having one section that corrects for distant vision, a second section that corrects for medium vision, and a third that corrects for near vision, as an eyeglass lens. 远中近三用的具有分别校正近距离视觉、中距离视觉和远距离视觉的三个部件的,如目镜透镜
- That can be addressed with multifocal lenses, which have concentric rings of material that offer alternate bands of near and distant vision. 这个问题可以使用多焦点人工晶体来解决,它拥有一些同心圆环,该圆环上的物质能提供交替调节近距离和远距离视力的区带。
- Having one section that corrects for distant vision,a second section that corrects for medium vision,and a third that corrects for near vision,as an eyeglass lens. 远中近三用的具有分别校正近距离视觉、中距离视觉和远距离视觉的三个部件的,如目镜透镜。
- The test chart consists of groups of lines arranged to form USAF standard test patterns. 测试图由一组按USAF的标准测试图案排列的线条构成。
- There is also a small (0.2%) amount of measurable - and visible - pincushion distortion at the telephoto end of the zoom ( click here for test chart ). 也有一小(0.;2%25)金额衡量-有形-枕形失真,在远摄年底缩放(点击这里测试见图)。
- Cosen is a professional machine vision test& measure equipment producer and emphasis on machine vision technology development and industry application. 专业从事机器视觉技术开发应用的检测设备。
- The VEP with optimal stimuli and threshold stimuli were recorded,then the relational universal test chart was analyzed statistically. 结果视觉诱发电位的最佳刺激视角和阈刺激视角与主观视力水平存在显著相关。
- Farsightedness is the opposite, in a way: A shorter-than-average eyeball or too-flat cornea focuses light behind the retina instead of on it, making near vision and sometimes distant vision blurry. 远视在某种程度上则相反,是较正常短些的眼球前后径或者太平坦的角膜使光线聚焦于视网膜后而不是之上,这导致近景视觉模糊和有时的远景视觉模糊;
- Nearsightedness occurs when the eyeball is slightly longer than normal or when the cornea curves too sharply, causing light rays to focus in front of the retina and blurring distant vision. 近视是眼球前后径轻微的变长或者角膜弯曲度大,引起光线聚焦于视网膜前,视远模糊;
- On the color tendentious test chart, the analysis color displacement's length and the angle may have the overall assurance to a model of camera's color style. 的程序,也利于让相机快速进入拍摄状态。而在闪光灯斜下方我们还可以看到为摄像功能新增的立体声麦克风。
- Permission from the youngperson's parents also is necessary.The young person also must passa test that asks questions about driving laws rules and trafficsigns.And he or she must pass a vision test. 青少年学习驾驶还须得到父母的许可,并通过一个有关驾驶的法律、规则及交通标志的问答考试,还要通过视力检查。
- It was found that 19 eyes (19/28) had VA improved more than 2 lines in standard logarithm visual acuity test chart , 6 eyes (6/28) had an improvement of more than 1 line and the rest (3/28) remained unchanged. 结果 :本组 19只 (19/ 2 8)眼激光治疗后 5米标准对数视力表视力提高两行或两行以上 ; 6只眼 (6/ 2 8)视力提高一行 ;
- An intelligent vision testing system is accurate,and at the same time, examiner can work with ease. 智能视力检测系统结果准确 ,检测范围广 ,同时能减轻医生的工作强度
- A simple test will show if this is real gold. 简单的试验就能证明这是否是真金。
- Many distant relatives fawned on the rich old man. 许多的远亲都来巴结这位有钱的老人。
