Presbyopia is a natural part of the ageing process of the eye. It is not a disease and it cannot be prevented.
The lens of your eye loses its flexibility, making it hard to focus on close objects.
Some signs of presbyopia include the tendency to hold reading materials at arm's length.
To help you compensate for presbyopia, your optometrist can prescribe reading glasses, bifocals, trifocals, varifocals or contact lenses.
You may only need to wear your glasses for close work like reading.
Since the effects of presbyopia are ongoing, periodic adjustments to your prescription may be needed for clear and comfortable vision.
