We’d all like to think we’re immune to ageing, but when it comes to vision Birkdale optometrist Martin McKenna said changes are inevitable.
“From the age of 40 onwards everyone will experience changes in their near vision,” Mr McKenna said.
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 focused for distance vision,” he said. “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 result 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 and may need your prescription changed every few years,” Mr McKenna said.
