Contact lens wearers have been told that eye disease mainly affects those in old age.
Cathy Yelf, head of external relations at the Macular Disease Society, said that age-related macular degeneration is the most common cause of sight loss in the western world.
She added that more than half a million people in the UK blame their sight loss on macular degeneration.
The expert went on to say that enjoying a healthy diet can play an important role in eye health, with those missing out on omega 3 fatty acids having more chance of developing macular degeneration.
"It"s interesting that other nutrients, such as vitamin D, may also play a part. In a way this is to be expected as it"s clear that what"s good for our general health is also good for our eyes and vitamin D is a vital part of a healthy diet," she told contact lens wearers.
Recently, the University of Buffalo found that women under the age of 75 who had high vitamin D intake were less likely to suffer from early age-related macular degeneration.
