An acuity test was developed with defined space between symbols to determine the effect of crowding on visual line acuity. The test differentiates between normalsighted subjects, those with low but uncorrected refractive errors and amblyopes. Furthermore, the test allows a quantitative examination of the crowding phenomenon and a measure of progress during amblyopia therapy. In normal-sighted subjects a maturational effect on visual line acuity was found, reaching the maximum test level at approximately the tenth year of life.
开发了一种视力测试，该测试中符号之间的间距是确定的，以确定拥挤对视力的影响。该测试能够区分视力正常的受试者、有低度但未矫正屈光不正的受试者和弱视患者。此外，该测试还能对拥挤现象进行定量检查，并衡量弱视治疗过程中的进展情况。在视力正常的受试者中，发现了对视力的成熟效应，在大约10岁时达到测试的最高水平。
