My 89 year old father was developing macular degeneration. I don’t know which kind. My brother and I bought him a blender and I showed him how to make a mostly vegetable based and a more fruit based blender drink. I urged him to take at least two of these each day. He died 4 months from an anger induced stroke. He never followed my advice to get help dealing with his severe anger outbursts.
At any rate, when I was going over his bank statements and photos of checks he had written, I noticed that over those 4 months his handwriting had gradually improved, so I think the raw blender drinks were helping his vision.
There’s a special vitamin the docs advise taking. Didn’t help me although I guess it could be worse without them.
