I used Transitions for years but don't think any were gen 8. The problem I had with them is that they are temperature sensitive. On a typical AZ summer day they hardly darken at all but they go nearly black on a ski slope in winter. No issues with seeing cockpit displays of any sort but cockpit windows may reduce the amount of UV that reaches the lenses.
I don't need prescription lenses for distance any more and fly with plain glass dark lenses with stick on fresnel readers
