PRESBYOPIA actually not a disease itself, it is a natural part of aging and is in general the gradual loss of your eyes' ability to focus on nearby objects as the lens is hardening and loosing its flexibility causing the eye to focus light behind rather than on the retina when looking at close objects.
In fact, the term “presbyopia” comes from a Greek word which means “old eye”. Presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 65.
You may become aware of presbyopia when you start holding books and newspapers at arm's length to be able to read them
There is no way to stop or reverse the normal aging process that causes presbyopia. However, presbyopia can be corrected with glasses, contact lenses or with surgery.
