Before my cataract surgery I did have a lot of night driving flare from oncoming headlights. That went away after surgery. The cataracts caused the lens flare and were hazy to look at in the mirror. I had surgery on one eye first, then the other one a few months later. After the first surgery I was amazed by how blue and bright the world looked, while the other eye still produced a dim yellow world. My surgeon told me that the natural lens yellows with age and gets dim ( read like looking through a dark yellow filter). Maid perfect sense. After surgery on the other eye the world looked the same through both eyes. Both times, when I left the facility (my wife was driving of course) after the roughly 1.5 hour surgery I couldn't see a thing, but by the time I got home a half hour later I could see well enough to drive but was still too untrustworthy to actually drive due to medications.
