once AMD occurs, carotenoids may slow down the deterioration of AMD. Although AMD does not cause pain, it can cause loss of central vision, and it usually affects both eyes.
At present, there is no cure for AMD. However, AMD does not affect the vision around or in the side, that is to say, will not cause total blindness.
The study also found that people with high levels of other forms of carotenoids (alpha carotene, beta carotene, beta carotene and beta) had a lower risk of developing advanced AMD by 25% to 35%.
