What do you mean by presbyopia?

Presbyopia is a condition associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects. The eyeglasses used have higher focusing power in the lower portion of the lens. Off the shelf reading glasses may be sufficient for some.
