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。

有5米选项就更好了
您好,我们也曾设计过5m的测试距离,但是由于我们是使用手机来测视力,所以屏幕尺寸会有所受限,因此没能有5m的测试距离选项。

这个视力表软件挺好的,但我发现50-70cm很轻松就5.2,放2.5米很勉强才5.1,不知道怎么回事。
