I wear glasses with transition lenses so they become sunglasses when they are exposed to sunlight so I get to have sunglasses outside at least. I wish I could get a pair of prescription glasses that are sunglasses all the time but that's not an option. To answer your question though yes, I feel better with sunglasses.
I have transitions as well. The only problem with them is that they don't change very well in cold weather, which is about 9 months out of the year in Wyoming. I'll be biking home from the University in a southerly direction, and the angle of the sun coupled with snow/ice glare will turn them almost opaque black. Then I get home and I'm stumbling around for twenty minutes until they change back to their normal clarity.
I've worn transitions for most of my teens, and despite the problems they work well. The only other problem is when you are driving, since they need UV light to change and cars already have UV filtering on the windshield and windows.
I once read about a motorcycle helmet that had a one-color LCD sandwiched between two plastic panes on the visor. You put in a couple of batteries, and it had a photocell which would measure light intensity and adjust the opacity of the LCD to compensate. The system is probably too bulky for normal glasses, but it would be a great concept.
