超级视力表APP究竟比纸质视力表好在哪？

一张标准的视力测量表价格通常不到五块钱，买一张悬挂在家中，可以随时为孩子测量视力，其实已经是一种很方便的监测视力变化的手段了，那么我们为什么要在手机上下载一款软件来进行视力测试呢？

固定的视标可能对测量结果的准确性产生巨大的影响

纸质视力表的视标通常是固定的，在长时间的使用过程中，潜意识可能会对视标方向产生记忆。尤其是对于低龄儿童来说，可能会刻意记住来获得更高的“分数”，这样一来，视力测量结果将会变得毫无意义。如果准备多张视力表，不仅替换起来十分麻烦，收效也可能并不显著。

超级视力表APP则完全不存在这个问题。在使用App的测试过程中，视标是随机生成的，完美避免了潜意识记忆对测量结果的影响，极大的提升了测量的准确性。

环境光源也可以影响到测量结果

根据标准对数视力表（GB-11533-2011）国标的要求，视力表应采用人工照明，如果采用直接照明法，照度应不低于300lx，如果采用后照法（视力表灯箱或屏幕显示），亮度应不低于200cd/m2。在使用纸质视力时，家中照明的灯源亮度很可能无法达到亮度的要求，即使是在白天测量，也可能由于阴天和晴天的变化，影响测量结果的准确性。

而对于现在的智能手机而言，亮度完全满足标准的要求，同时超级视力表采用了“后照法”的照明方式，亮度固定，保证每一次测量都是在同样的条件下进行，极大地确保测量结果的准确。

记录方式便捷，随时随地都可以进行测量

在使用纸质测量表测量时，需要手动记录数据，这不仅会因为人为记录错误而导致误差，还存在数据遗失的风险。

超级视力表能够自动记录测试数据，并生成视力档案，还能够以折线图的形式将整体的视力变化趋势一目了然地呈现出来。同时，数据保存在用户账户中，不会因为手机的丢失而造成数据缺失。

除此之外，利用超级视力表，随时随地都可以进行测量，即便是出门旅行，也可以保证测量数据的连续性。
