Tried them once, never again. Having to move your head side to side to read a book is kind of like moving your lips, IMHO. Had lined bifocals for awhile, but had to take them off and put on reading glasses for the computer. Eventually went to lined tri-focals- love them.
In other news, its about time to go to optometrist for exam and new glasses. Am on Medicare now, and my Advantage plan requires me to get a referral from primary care physician to go to any "specialist", including the optometrist! How silly is that? I think its so primary care guy can get an office conference fee and copay- but mine just lets us call in for a referral, when its obviously out of his line of work.
