Exercise for the eyes8th November 2006
Research has shown that regular exercise can not only lengthen life, but also prevent blindness in old age.
People who take rigorous exercise three or more times a week have a 70 per cent less chance of developing age-related macular degeneration.
Even more gentle exercise can help, with daily walking cutting the risk by almost a third, according to a study published in the British Journal of Ophthalmology.
Age-related macular degeneration is the most common cause of blindness in the elderly and affects the vision of more than half of the over-75s. The condition causes central vision to gradually deteriorate, making it more and more difficult to carry out tasks such as reading or watching TV.
But now researchers from the University of Wisconsin looked at more than 4,000 people aged 43 to 86 about their exercise habits.
Fit people are generally ‘biologically’ younger, but exercise may keep the vision sharp by keeping eye blood vessels healthy into old age.
Other studies have shown that those who regularly eat oily fish are less likely to develop AMD.
