The first achievement of this investigation was a development of a visual acuity test based on the new technology of micro-computers, though its basic principle was not different from the traditional opto-chart test techniques. This relates to the outcome of the first year investigation in which the variables were 'hues' of the target stimuli and their contrast from the background. Although the results were not particularly new, through this study the possibility of acuity measurement and data analysis by means of computers in the clinical situations was proved. The targets could be further developed to have higher sophistication and exactness. The second achievement of this investigation was the uncovering of processes of the visual system that underlie visual acuity. This was realized by clarifying tha factors that affect both the temporal and spatial resolutions of the visual system. Admittedly this may not lead immediately to the improvement of tests for clinical uses but would make possible separation of those extraneous factors that affect visual acuity. The most notable factors discovered in the present study were the factors of saturation when colored targets were used, and the spatial factors that affect temporal resolution. If these factors are taken into consideration, we could develop more meaningful acuity measurement techniques.

这项研究的第一个成果是发展了一种基于微计算机新技术的视力测试，尽管它的基本原理与传统的视力表测试技术没有什么不同。这与第一年调查的结果有关，其中变量是目标刺激的“色调”及其与背景的对比。虽然结果不是特别新，但通过这项研究，证明了在临床情况下通过计算机进行视力测量和数据分析的可能性。目标可以进一步发展，以具有更高的复杂性和准确性。这项研究的第二个成就是揭示了视觉系统的过程，这些过程是视力的基础。这是通过阐明影响视觉系统的时间和空间分辨率的因素来实现的。诚然，这可能不会立即导致临床使用的测试的改进，但将有可能分离那些影响视力的外来因素。在本研究中发现的最显着的因素是饱和度的因素时，使用彩色目标，和空间因素，影响时间分辨率。如果这些因素都考虑在内，我们可以开发更有意义的敏锐度测量技术。
