Apple devices could be suitable for vision tests, provided that the test has been correctly adapted to the device, after considering the spatial and colorimetric characterization of the screen.
The majority of vision applications has not been developed by vision or colorimetry experts and suffers from conceptual and design errors that may lead average users to an erroneous assessment of their visual capabilities. The reliability of vision tests depends on the accurate generation of the necessary visual stimuli in a particular device. Our aim was to ascertain whether a given color test, designed for a colorimetrically characterized device, might be used in another similar device.
We evaluated color reproduction errors in three iPad tablets of different models with Retina screens, using their individual color characterization models and the model derived for another device.
Our results showed, even with this small sample, the high degree of error caused when disregarding the fact that the colorimetric design valid for a given device may not be correct when displayed in another.
The distortion of the chromatic content may lead to subjects with vision defects to pass as normal or vice versa, compromising diagnosis reliability.
如果在考虑屏幕的空间和色度特性后，测试已正确适配设备，苹果设备可能适用于视力测试。
大多数视力应用并非由视力或色度学专家开发，存在概念和设计错误，可能导致普通用户对自身视觉能力产生错误评估。视力测试的可靠性取决于在特定设备中准确生成必要的视觉刺激。我们的目的是确定为具有色度特性的设备设计的特定颜色测试是否可用于另一类似设备。
我们使用不同型号配备视网膜屏幕的三款iPad平板电脑各自的颜色特性模型以及为另一设备导出的模型，评估了颜色再现误差。
我们的结果表明，即使样本量较小，当忽视适用于给定设备的色度设计在另一设备上显示时可能不正确这一事实时，也会导致高度误差。
色度内容的失真可能导致有视力缺陷的受试者被判定为正常，反之亦然，从而损害诊断的可靠性。
