worked great
I was skeptical about these but for the price decided to give them a try.  I do not need biofocals all the time just for some cutting and crafting.  did not want to use my vision insurance on glasses i would not wear all the time.  so i thought i'd  add these to an old pair of glasses i had.  they were easy to put on and work great.  i was expecting them to be a little foggy but they are not just as clear as my glasses.  will be buying another set in the near future.
