It has been 6 yrs and at my last appointment my eye doctor said that I am still at the beginning of early stage. What I do is I wear Sleep ZM yellow tinted clip ons that transition when outside. They also have a fit over eyeglass version as well. It says daytime but it also works for night driving. I have read that wearing yellow tinted frames are good for those with AMD. They are anti blue light and UV blocking.

As for supplements, I follow the Areds 2 formula but take them separately. Prior to being diagnosed with AMD, I was taking 1,000mg time released Vit. C for my allergies and so decided to continue with that and add the rest of the Areds 2 ingredients separately. I take luetin, zethanxin formula with saffron and axthanxin which are also good for AMD and I also take bilberry. I take cod liver oil for the omega 3 and it also has vitamin e in it which is a Areds 2 ingredient. I have read that it is good to keep down inflammation with AMD so I take turmeric. Turmeric does reduce irons levels so I take a multivitamin with iron. The one I take has 18 mg of iron and that works well. Women do better with iron abortion by taking iron every other day so I take the multi with iron one day and then turmeric the next day and I take the non iron multi on turmeric days. I also take NAC and Melatonin for their anti-vegf properties to avoid Wet AMD.
I have read on this forum that the high amount of zinc that is in the Areds 2 formula can have a negative affect on some people and make AMD worse so I just take the zinc that is in my multi vitamin (with fruits and veg) and my thyroid support supplement which combined is 13mg. I looked into my thyroid support supplement and the thyroid blend also does double duty for AMD. So if your relative is already on a thyroid support supplement than it will also help with the AMD.
I also exercise everyday and eat right.
I hope that all of this is why I am still at the beginning of early stage 6yrs after being diagnosed.
