51 here. Been wearing glasses my whole life, only i have to keep getting them stronger. NSFF!! TRY THIS!!! I went to the eye doc. Told him my work area was 8-10 inches away from my eyes. He set me up witha set of specks. WORK GREAT out to 12 inches, then I can't see $hit!! But from 8-10 their the berries. Can't work without them now!!!! They work BETTER than my bifocals.
