One issue with modern life is that we spend an awful lot of time focusing at fixed distances, bright screen in dark room etc. I learned two exercises in Yoga for getting the eyes muscles into shape. The first is basically focusing at different distances: tip of the nose, outstretched thumb, window in front of you, and a tree outside for example; then repeat the sequence back and forth. And the second tracing/exploring the border of your visual field using the thumb by moving it as far left/right/up/down as possible without losing sight of it while keeping the head still.
