i had both mine done almost two years ago, after putting it off for years. It was the easiest thing to do, and if i knew how easy and how much better i could see i would've done it way sooner. The colors, the clarity, the easy night driving again, all were huge!! I'm still amazed how much better and clearer my eye sight is now....better than it has been in at least thirty years!! I didn't get any upgraded lenses when i had mine, and it is very rare that i even need my readers at all!!
