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.
