Myopic 225°,astigmatic 50°,astigmatic axis at 80°,vision 1.0

左眼：—2.25/—0.50x80，即近视225度，散光50度，散光的轴位为80度方向，视力为1.0

Object To calculate astigmatism axis by astigmatic dials test with mathematic method.

散光视标检查被用来判断被检者有无散光及散光的程度和轴位。

The results of corneal topography, that of keratometer and cycloplegic retinoscopy in measuring astigmatism before refractive surgery were compared, and the measuring results of corneal topography and that of keratometer for 72 eyes after photorefractive keratectomy and 95 eyes after laser in situ keratomileusis were also compared.

采用计算机辅助的角膜地形图、角膜曲率计及散瞳验光三种测量散光的方法，对屈光不正患者360只眼进行检查，同时对准分子激光角膜切削术（photorefractive keratectomy，PRK）后72只眼和准分子激光原位角膜磨镶术（excimer laser in situ keratomileusis，LASIK）后95只眼的角膜散光用角膜地形图和角膜曲率计进行测量并比较。

AIM: To evaluate the effect of wearing cylindrical lens on dry eyes.

目的：观察长期配戴散光镜对散光的干眼患者的治疗作用。

It was found that, for most subjects in the group, astigmatism changed in the with-the-rule direction, the mean change being -0.036 DC at axis 176 deg for each dioptre of accommodation response.

研究发现，多数病例都发生了循规性散光的改变，每矫正1个屈光度，循规性散光平均改变-0.036DC 。

The stray light is evaluated using the cut-off solution method and its effects were studied by means of simulation background absorption using potassium dichromate solution molecular absorption.

用截止溶液法检验了杂散光的存在，并用重铬酸钾溶液分子吸收模拟背景吸收的方法研究了杂散光的影响。

However, unlike the light source relative to the rest of the observer to see is the colorless astigmatism, and the light source relative motion of the observer to see is the red-shift light ( achromatous astigmatism occurs redshift of red-shift light ); Although the different inertial reference frame of the observer can see the speed of light, after the Lorentz transformation is the same as after c; but a different observer are exposed to the light energy is not the same achromatous (astigmatism energy and achromatous astigmatism occurs after the red-shift of red-shift of the light energy is out of the same ).

但是，与光源相对静止的观察者看到的是无色散光，而与光源相对运动的观察者看到的是红移光（无色散光发生红移后的红移光）；虽然，不同惯性参照系的观察者看到的光速，经过洛伦兹坐标变换后都一样为c；可是不同的观察者所承受到的光能量是不相同的（无色散光的能量和无色散光发生红移后的红移光能量是完全不相同的）。

This suggested that various hypermetropic refractive errors in infants may become "a risk" for the development of esotropia and should be corrected early with appropriate lenses, together with close observation of visual acuity and alteration eye position...

本文从历年来门诊检查的无斜视远视患儿和经专科门诊诊断为内斜视的患者中，分析了远视性屈光不正、两眼屈光参差及散光等数据，试图找出发生斜视&危险&的远视、屈光参差及散光的度数，以此

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
