Summary

Text and icons on displays should be readable, instantaneously, at a glance, for the vast majority of people, and certainly everyone who does not have near vision impairment. Learn what the threshold is for near vision impairment, and test your own vision to see whether your perspective of self-evaluating devices and displays means that display will be suitable for the wider population.

Learn how simulation glasses can be used to enhance self-evaluation so that better reflects the suitability of the wider population. Also learn how automated tools and algorithms can predict the necessary font size that’s required for an interface or display, and test digital screenshots to see whether the text within has adequate size and sufficient contrast.
