	受测者配戴远方视力最佳矫正度数眼镜阅读近方视标，验光师量测脑波讯号做为判定老视眼，并进一步搭配试镜架检查，完成脑波应用于近方视力量测技术的建立。利用脑波讯号的专注与放松曲线做为判定受测者所需近方屈亮度值及加入屈亮度值。这种结合脑波量测、主观屈光检查和客观屈光检查的创新方法，可以获得优化老视眼屈光度数(Diopter)。单极点脑波撷取器量测眼睛被刺激时视觉反应的额头脑波模拟讯号，由电子电路将此脑波模拟讯号转换为各种频率，经数学运算获得专注值和放松值作为判断受测者取得最适合的近方加入屈光度数。根据实验结果，本创新方法获得老视眼量测精度为0.5 D。<br />
The subjects wear the glasses with the best correction diopter of distant vision to read the near vision chart. The optometrist measures the brain wave signal as a judgment of presbyopia, and further combined with the examination of the trial frame to complete the application of brain wave to the establishment of near vision measurement technology. The attention and meditation curves of brainwave signals were used to determine the diopter of near vision and the diopter of addition required by the subjects. This innovative method, which combines brain wave meas-urement, examines of subjective refraction and examines of objective refraction, can obtain the best diopter of presbyopia. The single pole brainwave acquisition device measures the forehead brainwave analog signal of visual response when the eyes are stimulated. The electronic circuit converts the brainwave analog signal into various frequencies, and the attention value and med-itation value are obtained through mathematical operations as the most suitable addition diop-ter for the subjects. According to the experimental results, the measurement accuracy of pres-byopia is 0.5 D.
