Presbyopia is not an illness nor a temporary condition. It is a natural consequence of the eyes' aging process and it applies to everyone over the age of 45. It manifests itself in difficulties with seeing clope-up objects for example - while reading. With the passing of years the lense looses it's ability to accommodate - which means adapting to seeing from a distance. This process in unavoidable. It's effect can be compensated but the use of progressive lenses. Which allow one to see from different distances both close-up and far away. The changes that eve undergoes during involution apply to its every part as well as similar tissues in other organs.
