How come you can buy reading glasses for a few bucks at pharmacies or Wal-Mart, but they don’t make them for being able to see farther away?

Question

Is the lens grinding process more complicated or is there just too much variation in eyesight to make them feasible on a mass scale?

Answer 1

I am 65 and have bifocals. Reading glasses for me are about 3.25. Distance vision is okay, but it needs help. Interestingly, if I were to lose my bifocals, I could get some 1.5 reading glasses and be able to use them as distance glasses.
