I took a large envelope to the post office to mail.
The clerk behind the counter had his glasses at the end of his nose, looking through them to read the number on the meter. I had my glasses at the end of my nose, looking over them to count out the correct change in my hand.
Same pose, two different purposes, and neither one of us can stand to wear bi-focals.
I replaced mine with the cool Transitions lenses so I can have sun protection without keeping up with shades.
