: Is there a way of making text that is unreadable at high brightness but becomes readable as brightness is reduced? I am looking for a way of displaying text that is unreadable at high brightness

@Jessie844

Try pure white text on a pure black background, with a very thin condensed font, bold with small features (ideally a low x-height), with very tight kerning / tracking, and lots of space between lines.

With the screen mostly black, the readers' pupils will dilate. The edges of the white characters at high brightness will be less distinct due to increased glare and fuzzier focus from the eye letting in more light. With all the important details tight, it'll be harder to tell which character is which.

With brightness reduced, glare will reduce and the details will be more visible.

Very light grey on white may work. The key is low contrast so that when the brightest is cranked it blows out all the subtle colors.

If we look at first principles of the physics. Contrast reduction simply means less difference between colors. Offhand it is really hard to imagine a direct situation where this would work out.

However there might be a way to overlap the monitor with a screen that could do it.
