验光仪原为检验人眼球屈光度数的一种仪器,应用于临床,简便易行。其原理是利用凸透镜,离眼愈近则对眼的屈光作用愈弱,愈远愈强的原理。用一固定凹镜于眼前,籍两镜片间距离变化,可得出不同程度的屈光力,以代替不同程度之眼镜片测定受矫正眼的屈光度。目前,我院验光配镜的人数较多,配回的眼镜片度数,因为无镜片屈光计,无法测量,所配的眼镜片无法得知是否正确,因此笔者对验光仪做进一步研究,应用验光仪检查测量镜片屈光度,利用其 Refractometer was originally tested as a kind of eye refraction instrument, used in clinical, simple and easy. The principle is the use of convex lens, away from the eyes of the eye refractive effect of the weaker, more and more the principle. With a fixed concave in front of the mirror, the distance between the two lenses changes can be obtained in varying degrees of refractive power, instead of varying degrees of ophthalmic lenses measured by the correction of refractive power. At present, the number of optometry optometrists in our hospital more, with the degree of spectacle lenses back, because no lens refractor, can not measure, the lens with the lens can not be found to be correct, so I do further research optometry, application Refractometers measure the refraction of the lens and use it
