Found in the revised version of some academic issues, talk about their own views. First, the standard near-visual acumen reprint instructions published in 1955, “on the standard near-visual acuity chart,” pointed out that the distance between the two visual acuity should be designed to use the same standard, the results can be compared with each other for the ophthalmology clinical eye flexion Light does not make a quick initial diagnosis. Now the country has developed a unified standard for the design of the far-visual table, so the standard near-visual acuity table should also be revised in accordance with national standards. National eye chart published a total of five indicators. ① 1 visual acuity for normal vision, ② three horizontal and other long as the standard E word, ③
