A group of scientists in Co Waterford has said that millions of euro can be saved by the State if it acts on the results of 11 years of clinical trials into age related macular degeneration.
The Macular Pigment Research Group, based at the Waterford Institute of Technology, is a world leader in the study of nutrition and vision.
Age related macular degeneration is a chronic eye condition that involves the loss of central vision.
It is the leading cause of blindness in people over 50 in Ireland.
Over 85,000 people in Ireland have the condition.
The figure is set to increase, as society is getting older.
Scientists at the Vision Research Centre in the Waterford Institute say nutritional supplements can prevent the condition developing in the first place.
The MPRG's research has shown that nutritional supplements can also improve the vision of people with early-stage macular degeneration.
