The Radio 4 Appeal today was presented by Henry Blofeld on behalf of the Macular Disease Society. I thought it was a pity that the opportunity was not taken to mention that there is evidence of a dietary measure that can help with this condition. See this BBC2 webpage. Eating spinach helps to prevent "age-related macular degeneration", a major cause of poor eyesight and sometimes blindness. It can even repair some damage to the macula that has already occurred! - The nutrient involved is lutein. This nutrient is also contained in kiwifruits, leeks, peas, eggs, broccoli, etc. You can find them easily by using a search engine. Maybe Henry Blofeld would like to try this dietary measure for himself, since he is himself experiencing macular degeneration.
