Elderly Challenge - Observation 1

I have noticed that elderly have bad eyesight. I have also noticed that, at the bus stop, the bus numbers shown and the bus stops those buses stop at have very small wording and numbers. The elderly might mistake some bus numbers for another and might end up lost after taking the wrong bus. They might also be unable to read the small wording which states the bus stops which each of the buses stop at. Therefore, they have a great chance of getting lost when using the buses, especially when they are alone, without anyone younger such as their children.
