I've been using them for over 20 years and personally I think they're better. I have to wear lenses all the time for driving and don't want the additional weight of those clip-on things. The only problem I ever encounter is when going from bright sunlight into a darker place (i.e. my local). Then I have to take them off until they've gone back to normal.
I've never, either in this country or abroad, found that the light was too bright behind them.
