I had cataract surgery at age 50 (60 now). Only one eye needed it but had both done because the new eye focused in a different plain than the other and drove me batty

. Might want to check with your eye doc to see if doing the other eye might help

I wound up 20-25 and 20-30. I too had floaters but they seem to be diminishing. I also am having some double vision mostly when I'm tired. Just had an eye exam and was told at this point not to worry. It sucks getting old
Red on the bottom and yellow on the top works the best for me. In the photo of my Breitling CAP I did large (1/4 of wing) red/yellow blocks on the bottom. That works pretty good. The graphics on the top disappear at distance. Good advice about always being able to see a wing on a biplane. I have a Goldberg, Bucker Jungman on the bench as I write. My first bipe in 30 years. I'll see how it compares in visibility.
