Experts have given advice to people to help combat the effects of the ageing process on their eyes.
EyeCare America urged people over 65 to have regular eye checks to help spot problems such as glaucoma and cataracts.
In addition, it is important to wear sunglasses that offer at least 99 per cent UV protection.
Eyes need to be kept lubricated and artificial teardrops can be used if someone suffers from dry eye.
Sufferers could also avoid smoky or windy environments and use humidifiers and wraparound glasses.
In addition, people should research their family history to see if they have any relatives with eye problems such as glaucoma or age-related macular degeneration, which can be hereditary.
Tom Kneier recently used an article for Catholic Online to describe how he started wearing contact lenses in order to make himself appear more youthful.
He explained that his wife had told him the contact lenses made him look younger.
