I hope someone here can point me in the right direction (if there is
one!)  My husband has been nearsighted all his life, and wears glasses.  
Due to age, his nearsightedness has reduced itself somewhat, and he has
a new problem.  He likes to read or use his laptop while watching TV (TV
is across the room), and finds his glasses are annoying when he drops
his eyes down to read.  He has to keep taking them off, and putting them
on to switch back and forth.  
What he would like to find out is if there exists an upside down half
size eyeglass, wherein the prescription glass would be up high, to look
through for TV, with NO glass of any kind on the bottom.  Yeah, they
would look funny, but he'd only use them at home.  Regular bifocals are
not what he wants, even with no prescription "blank" glass on the
bottom.  He'd like to look down through NO glass at all.  
Does anyone know if such a thing exists, and where to find them if they
do?  I appreciate all information.

J.
