Were your other glasses, bifocals? I could never get used to bifocals .. had to have separate reading glasses.
I love my bifocals; they are excellent for me, allowing me to see the computer keyboard (or a book, or script bottles print, etc)) with the lower lenses,
and to see the birds outdoors, with the top ones.
And I am thus able to look up from the computer keyboard, out the window, and back....without switching glasses...
though I do know that many people do find bifocals too difficult to wear, so it's just not for them!
It even could make some people dizzy on stairs, if they don't get the focus well enough.
One thing about them, is that they do need to be measured very correctly, and sometimes, they don't get them just right.
Each of the 2 lenses needs to work for the distance you would be routinely using them for.
The older we get, the less capable our eyes are at flexing for various distances.
If you've had bifocals before,
@hawkdon
then it shouldn't take long before you know if they are right or if they need to be adjusted.
Or you might prefer them to have the bottom lens script so that it is the sharpest view, at a different distance than it is now, to get the best clear focus, at whatever you usually look closely at, whether it's labels or book or computer.....
Computer screen is usually farther away, than reading.
I have had trifocals in the past, which worked for me at that time, so I could see things at the various distance. Such as cards or puzzle pieces on a table, would be for the middle distance.
I got used to them quickly, because I could see more things than I had been, without them.
But again, they're not for everybody!
