在视力分析中,经常碰到视力低下的不同时期分类问题。视力分类非同其他指标的分类。因为视力下降幅度一致时,不一定表明眼睛的结构变化程度一致,也不能说明眼睛的视力负担和困难程度是一致的。相反,下降幅度不一致时,不一定标志眼的变化不一致。故视力低下的分类,笔者试用模糊聚类。
In vision analysis, problems of classification in different periods of low vision are often encountered. Vision classification is not classified with other indicators. Because the visual decline is consistent, it does not necessarily indicate that the degree of structural change of the eye is consistent, nor does it mean that the eye’s visual burden and difficulty are consistent. Conversely, when the magnitude of the fall is inconsistent, it does not necessarily indicate inconsistent changes in the eye. Therefore, the classification of low vision, the author tried fuzzy clustering.
