description The invention provides a method, a system and a device for measuring visual acuity of a client in clinical visual acuity measurements. In accordance with the implementation, the system comprises a display device (41), an input device (42) and a computing device (43). The display device (41) is capable of displaying sets of symbols in different size to the client. The input device (42) is capable of receiving responses of the client indicative to the identity of the symbols, and the computing device (43) is capable of a) registering (S431) values to the responses belonging to pre-calculated values of similarity of the symbols, b) calculating (S432) a rate of recognition value for each symbol size, and c) determining (S433) the measured visual acuity from the rate of recognition values. 提供了一种在临床视觉敏锐度测量中用于测量用户的视觉敏锐度的方法、系统及设备。根据实施方式，该系统包括显示设备(41)、输入设备(42)和计算设备(43)。显示设备(41)能够向用户显示不同尺寸的符号集。输入设备(42)能够接收指示符号的标识的用户响应，以及计算设备(43)能够：a)登记(S431)属于符号的预先计算的相似度值的针对响应的值，b)针对每个符号尺寸计算(S432)识别率值，以及c)根据识别率值确定(S433)所测量的视觉敏锐度。
