From the age of 40 onwards everyone will experience changes in their near vision.
This common condition that makes vision difficult at a normal reading distance is known as Presbyopia. This is a normal change in the ageing process. Normally your eyes are focussed for distance vision. To focus on close objects, a muscle in the eye changes the shape of the lens. When we get older the lens loses its flexibility and is less able to change its shape, making it difficult to focus on close objects.
People with presbyopia may have difficulty concentrating when reading or may find that periods of close work results in sore eyes, headaches or tiredness. Although like stiffening joints or greying hair, presbyopia cannot be prevented, it can be corrected with spectacles or lenses.
As your ability to focus weakens, you will need to have regular eye examinations every two years and may need your prescription changed every few years. Regular examinations are also essential for people over the age of 40 to keep track of other potential eye health problems. Presbyopia will continue regardless of whether or not spectacles are worn. Wearing spectacles does not accelerate or slow the development of presbyopia.
