I tried progressive bifocals and hated them. Part of the problem may be there was no explaination of how to use them or what to expect, so I never learned to use them. When the progessives didn't work for me I got mad, went to a different eye doctor and got lined bifocals. I probably should have gone back to the first doctor and had them adjusted, had them replaced, or had them teach me how to use them.
I save my old single lens reading glasses for use as computer glasses. As my eyes change the focal length of the old glasses grows closer to my arms length, they become perfect for seeing my desktop computer screen which is an arms length away.
