Yeah I struggle with eyesight a lot, and so I used to have to stop all the buses as I can only see the destination close up, though white blinds are a bit easier. Now I check all my buses on Bustimes so I know what type of vehicle to expect and when it is coming, so I only have to stop the wrong one if it is the same vehicle type at the same time as the one I want.

Clear destinations are very important though, hopefully from an eyesight point of view, adding in this A, B and C, does not make the service number smaller so harder to see.
