视力差的

But my eyesight becomes poorer and poorer, and I am not able to finish my homework on time.

但我的视力变得越来越差了，而且我无法按时完成我的功课。

If we have poor eyesight, it will be difficult to see everything clearly.

如果我们的视力很差，也很难都看得清楚了。

The induced changes in log mesopic contrast sensitivity showed significant negative correlation with the changes in third-order (r =-0.490, P =.0013 without glare; r =-0.362, P =.0177 with glare; Spearman rank correlation coefficient) and fourth-order root mean square (r =-0.586, P =.0001 and r =-0.306, P =.0450, respectively).

中间视力对比敏感度log值的变化与三阶像差(r =-0.490， P =。0013 无眩光； r =-0.362， P =。0177 ，有眩光； Spearman 等级相关系数)和四阶像差(r =-0.586， P =。0001无眩光；； r =-0.306， P =。0450有眩光，)的均方根呈显著负相关。

Pulitzer paid a price for his unsparingly rigorous work at his newspaper.9 His health was undermined and, with his eyes failing, Pulitzer and his wife set out in 1883 for New York to board a ship on a doctor-ordered European vacation.

普利策对报纸的工作不遗余力，过分投入，终于付出了代价：健康日渐衰退，视力也越来越差。1883年，遵照医生建议，普利策携妻子出发到纽约，登船去欧洲度假。

After entering the college, i have been reluctant to write, regardless the happiness or the bitterness, the unforgettable or the boresome matters.

不知道是我视力越来越差，还是什么，在学校里撞见的熟人少多了，偶尔撞上一个也会莫名的一阵欣喜。

There were some specific examinations according to conditions of different patients, including multipoint corneal thickness, time-related keratometry, glare, contrast sensitivity, function of muscular apparatus, VEP, and so on.

除视力、屈光度、主视眼、角膜厚度、角膜地形图、像差检查等常规术前检查外，还要依据患者情况进行相应的特殊检查，包括角膜多点厚度、角膜曲率时间变化、眩光仪、对比敏感度、眼肌功能、VEP五项等检查。

METHODS: In 44 eyes of 22 subjects (mean age +/- standard deviation , 24.0 +/- 3.2 years) with orthokeratology, ocular aberrations and mesopic contrast sensitivity were determined before and three months after commencement of the procedure.

对22名受试者（平均年龄±标准差，24.0±3.2岁）的44只眼在接受角膜塑型术治疗前和治疗后3个月时测量眼像差和中间视力对比敏感度。

And they were visual acuity, contrast sensitivity function, accommodation and vergence ocular optical aberration and cortical topography.② From the general data collection, the volume of refractive surgery was in the development curve from sharp up to flat up trend, LASIK was the domain one.

结果 从以不同角度设计的临床基础研究中总结出与视觉功能有关的参数，主要有视敏度和对比敏感度视力、调节和辐辏功能参数、眼球像差、角膜形态参数。

Don't wait until your vision deteriorates to have an eye exam.

不要等到你的视力变差才去做检查。

And salamanders have poor eyesight.

而且它们的视力也很差

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
