I also had trouble getting used to bifocals, but I had the line. The optician told me I could come back and exchange the lenses up to 30 days later at no additional cost. I ended up taking him up on the offer, because I never could get comfortable with the new lenses.

How are you doing with other tasks such as walking and etc? I was falling and hitting my head on things.

Now I have separate glasses for looking and reading. I tie with the reading glasses. I'm no rocket surgeon, but I think you won't be able to use drugstore readers if you have an astigmatism prescription.

Good luck.
