If you have an iPhone, it can warn you if you’re holding it too close if you enable the warning. Turns out I do that a lot, without realizing

One time during a long screen time session I happened to notice by accident that looking at the reflection of the screen in the office window produced almost no eye strain even though I could comfortably make out all the text off the screens reflection. Made a mental note to research into this for a potential solution but never got around to it. Find myself imagining if some setup based around a semi-transparent screen which absorbs/reflects away just the right amount, combined with a mirror to simulate long distance could be worth experimenting with for someone sufficiently motivated. Think of the setup in the opticians office where you read letters off a mirror, but semi transparent. Has anyone seen anything akin to this?
