Stay away from "Rip Off's 'r Us" I don't know how they stay in business. An Obtrusibe clerk estimated $59 to fix the ear on my frame and wouldn't guarantee how log they would last. I( don't think I paid that much for those reading glasses total. Then she estimated $419 for a new prescription with out even seeing my prescription or offering to show their very and obviously overpriced frames.
They should get rid of her. I don't think I've paid more than $100 for reading glasees to for which she assumed were bi-focals.
Again: Rip Off, Rip Off and Stay away. Go to Costco or Walmart.
