bowgy, I got my first pair of glasses last yr at nearly 50, in part do to 26 yrs of burning welding rod,I went from 0 to progressives over night. Have no fear, you will adapt just fine in no time. I received my glasses 2 days before our annual turkey camp in the Hoosier Nat. forest here in Indiana, damn near broke my nose falling on my face 1st morning out, I figured out real fast that I should have taken a few walks in the woods previous to the hunt to get acclimated to the glasses. Once you get acclimated, the world is a beautiful thing to see, once you can see it clearly.
