Life-changing!!
I bought several pairs and put them on a few pairs of sunglasses and my onion goggles.  It's fantastic to be able to see the dash controls when I am in the car, and stuff like menus and my phone when I am outside without having to switch glasses.  And safer cooking!  I actually cut myself while trying to use my onion goggles because I am super sensitive to the fumes and was having to wear regular readers and blubbering while I chopped, which was also dangerous for me.  No more!  These little lenses have been lifesavers.  I just love them!
