Please add 20/400
Response from developer
But if John the patient can not see 20/200, isn't he already legally blind. Nevertheless, you can still test 20/400. For example, change the app's test distance to 10 feet, but actually test at 20 feet with an optotype of 20/200, the largest the app can display.
Solid app

Are you suggesting to have multiple rows? or you want to 2 meters test distance? I am aware that doctors have been using the app in wards. Shall we have a conversation by Email? please send to s AT Fonlow dot com or just use the app's "Send Message to Developer" feature.

仅在更改大小时出现一次。 尺寸供参考, 供你验证此App 很准确,当用把尺度量时。 您是阅读了视标以测试您的视力。 Appear once only when changing size. The size is only for reference. You read Optotype for testing your eyesight.
没办法自定义距离

您需要按键盘上的Enter确认更改。 这适用于需要输入数字的所有应用，这些应用由iOS的UI基本行为定义。 You need to press the Enter in the keypad to confirm the change. This applies to all apps that need number input, defined by the UI basic behavior of iOS.
