Conclusion the length of axis, corneal refractive power, lens thickness, anterior chamber depth and age have certain effect on the spherical equivalent refraction.

与角膜厚度、眼压无明显的相关性。结论眼轴长度、角膜屈光力、晶状体厚度、前房深度和年龄对近视度数(等值球镜度数)均有一定的影响。

The DGH-4000 Ultrasonic Pachymeter was used in the measurement of the anterior chamber depth (AD), lens thickness (lt) and axial length (al) in 72 patients with myopia and 18 individuals.

应用dgh - 4000型眼部A型超声测量仪检测了72例近视眼及18例正常对照眼的前房深度、晶体厚度及眼轴长度。

When in use of the lens thickness gauge, the force bearing area of the lens is greater, thereby avoiding the measurement errors caused by the deformation due to the local force bearing of the lens.

使用该透镜测厚仪时，透镜的受力面积较大，从而可避免透镜局部受力产生形变而造成的测量误差。

Just 12.2mm slim (measurement excludes lens cover), which is smaller than the thickness of a standard AA-size battery, the Cyber-shot TX55 is the world's thinnest camera in its class (among cameras with an optical anti-shake function).

Optical correlators, meanwhile, work by encoding images on to a beam of light and, using a special lens, transforming them into their Fourier components building-blocks that encode the thickness and direction of lines in the image, but not their position.
