There isn't any evidence that looking at close up objects causes any permanent harm to eyes.
Losing the ability to focus on close up objects with aging (presbyopia) is just kinda one of those things that happens. The lens slowly becomes less stretchy (elastic) and won't fully snap back into a round shape when tension on it is released.
