Lowercase standard font on a smartphone can be as small as 1.1mm for the height of the letter “a” on something like an iPhone 6, or even smaller on a smaller phone.
With your phone brightness set to the lowest level, how far away (from your eye, not glasses) can you comfortably read that size text on your phone in low ambient lighting?
And is this with glasses or no glasses?
I often read about people being able to read it from arm’s length on here. That is like 60cm.
I’ve never been able to read well on a phone, and have to hold it very close, like 25-27cm (without glasses). Glasses don’t really help me extend that distance at all when it comes to the phone screen.
