A combination of vitamin C, vitamin E, carotenoids and zinc has already been shown to be modestly effective in slowing the progression of the disease when taken in tablet form.
Now researchers are hoping to slow the disease still further by examining a specific nutrient called lutein which is found in spinach, broccoli, kale, corn, green peas, lettuce and collard greens.
And they are calling on anyone with the condition who wishes to take part in the study to contact them.
Lutein is believed to protect the macular - the central part of the retina which gives us the most detailed vision.
Scientists believe the nutrient destroys free radicals which damage the retina and absorbs short wavelength light, which is most damaging to the eye.
Hannah Bartlett, researcher at Aston University, said: "There is some research that suggests taking these supple-ments on a daily basis may prevent or slow down the progression of ARMD.
"At Aston we are conducting a study to try and determine the role of nutritional supplements."
She said that people could reduce the risk of developing the disease by eating a diet rich in green leafy vegetables and fruit.
