目前比较常用的记录视力的方法有分数视力、对数视力、小数视力,还有直接用视角或设计距离来表示的各种视力。分数视力是指用检查距离做分子设计距离做分母,以分数的形式来表示的视力,这是英国和美国常用的视力表记录视力方法之一。对数视力是指视角经过对数处理用五分记录法来表示的视力,这是我国缪天荣设计 At present, the more common methods of recording visual acuity are fractional visual acuity, logarithmic visual acuity, fractional visual acuity, as well as various visual acuities directly expressed by the viewing angle or the designed distance. Fractional visual acuity refers to the distance from the examining distance to make the numerator design of the denominator, expressed in the form of fractional acuity, which is one of the commonly used methods of visual acuity recording in the United Kingdom and the United States. Logarithmic visual acuity refers to the view through the logarithmic processing with five minutes recorded to represent the vision, which is China’s Miu Tian Rong design
