Two important questions: How far away are you from the screen and how
old are you?

Assuming that your distance vision, which is defined as 20 feet and
beyond, is corrected properly, you may need a presciption that is
slightly different for use at 12 feet. Once a person gets past their
late 40's, they usually do not have enough accommodation (the ability
to change focus) to see as comfortably as they used to at that 5 to 15
feet range.

A progressive ("no-line" ) bifocal may be the answer because it has
those intermediate ranges built in. However, depending on the angle of
the direction of the TV, there may be a slight head tilt necessary to
see where you want to see.

Some of my patients chose to simply leave their distance prescription
slightly under corrected if they are near-sighted or slightly over
corrected if they are far-sighted.

Hopefully, I answered your question.

Great info Dr Jeff!!

I'm 46 and and got my first set of bifocals (no-line).
I got over the "Fishbowl effect" in just a few days.

When I get back into my house (Hurricane Ivan) in a
few months and build the new Home Theater, if I run
into a prob I'll make a pleading post for help here. LOL

Going with a 60" Plasma, LCD, or DLP.
And have about 20' of viewing distance to adjust
with to adapt to now watching a 60".
