Hi Vince,
Had a buddy that flew Control Line stunt until he couldn't fly no'mor with cataract's (the model is only 70 feet away, but he was seeing two of them!). He had a hard time seeing at night, driving was iffy, and he said the best thing he ever did was get the lenses. He got them at 63 years, about.

Dad got his lenses in 2008, I think. He was 76 then. He flies every day, stays in a little close, but then we often are not sure what maneuver he is doing, and he says he often doesn't either!
Whatever the newest thing (lens) is, with the best doctor you can find, seems the best. A buddy got his done at 36, he is a professional pilot and they are very reliable according to him.
All of the plus-70 guys in Punta Gorda have them, it seems.

Chris...
