测量屈光不正的技术称为验光。验光在临床工作量中占有相当大的比例,人们曾对此付出了巨大的劳动。随着科学技术的发展,新型的自动验光仪在七十年代应运而生,这类自动验光仪系用了红外、电子、计算机等一系列先进技术,完全超出了单纯应用光学方进行验光的范畴。它利用了红外及自动雾视装置以达到放松调节和散大瞳孔径的目的,并不因注视发光标记而调节;因应用计算机模数转化技术,屈光度可自动显示在荧光屏
The technique of measuring refractive errors is known as optometry. Optometry in clinical work occupy a large proportion of people have paid a huge amount of labor. With the development of science and technology, a new type of automatic refresher came into being in the seventies. Such automatic refractor uses a series of advanced technologies such as infrared, electronic and computer, completely beyond the scope of pure optometrists for optometry . It uses infrared and automatic fog device to achieve the purpose of relaxation regulation and dilation pupil diameter, and not due to attention to the luminous mark to adjust; due to the use of computer module conversion technology, refraction can be automatically displayed on the screen
