From google: "A majority of 61 percent in the population reported to wear glasses, contact lenses or other reading or visual aids occasionally in 2012"
Create a basic/classy simple digital watchface with two lines of information both in the largest practical sized typeface. An upper line with the time and the lower line with the one of the other stats. By tapping the lower line it changes to another stat such as: heart rate, steps, date etc.
I currently use Argle which is nice and classy and I can see the time, but have to put my glasses on to see the tiny stats. The lower stat changing when i press it.
A wonderful watch, loads of great stats but problematic for me and I presume many over 50 yo.
