I can't see diddly on a sectional anymore without holding it four
inches from my eyes. Can anyone recommend "progressive" bi-focals?
How about TRI-focals? Any benefit there?

Jay,
I've tried bifocals and had a big problem with the "line" where the two
different focal length sections of the lens intersect. This was after using
Varilux lenses for about 10 years. I had my doc order both my new Varilux
set and a bifocal set with the same prescription. I am nearsighted with a
required correction of -2.25 in one eye and -2.75 in the other eye.

I never could get used to the bifocal line so I never tried tri-focals. I
stayed with the Varilux. It is a love-hate relationship. The variable
focal length lenses have a small "sweet spot". They must be positioned
carefully on my nose and they are poor performers "off-axis" to the left or
right of center.

To adjust for the proper focal length, you must learn to nod your head
slightly.

So I need to swivel my head to directly view an object or scene, then
slightly tilt to get the proper focus. They work well, but I do more head
movement than the average Joe. YMMV
