I have used Photochromic lenses for decades, originally Zeiss but now Pilkington which are a little slower to adjust to base level.
Reason being I have overly sensitive eyes, I can see better in low light that anyone I have ever met.
Also mine are 'merged' bifocals, naffing expensive but I value what I can see as I was a Printer and am an enthusiastic photographer.
So accuracy of image means a great deal to me, the eyes / brain adapt very swiftly and I find no problems with them.
