It is known that presbyopia is mainly caused by the aging. That is because in our eyes, there is a circular muscle, which enables us to see things at different distances by changing shape, expanding and contracting the focusing power. When we are young, this muscle is very flexible. And when we are getting old, this muscle loses the flexibility day by day. So the power to focus is not strong any more. As a result, we can not focus on the things near us, but in a certain distance.

First, surgery, like Lasik, which involves the reshaping your cornea, but some patients still need to wear reading glasses after surgery.
