Bifocal contact lenses could help to correct the eye condition presbyopia, it has been suggested.
In an article for the Breaking Story, Paul Swadya said: "As the eye ages, a certain amount of visual acuity is lost and by the age of 40 or 50 many people show the first signs of presbyopia."
Wearing contacts can help to reduce the effects of the condition, he said.
According to the NHS, presbyopia is more commonly known as age-related long-sightedness.
As well as addressing presbyopia, focal contact lenses can also help to ensure a person looks younger.
This is because reading glasses are traditionally associated with older people, meaning that there can be a negative perception of them, he said.
Recently, specialists from the University of New South Wales School of Optometry and Vision Science said they needed volunteers for a study looking at how presbyopia could be treated through the wearing of overnight contact lenses.
