I purchased prescription glasses at Walmart for the first time. NEVER again! The anti scratch coating doesnt work at all. After 8 months I wasnt able to see clearly they were so scratched up. I tried to get a refund for just the lenses so I can purchase elsewhere, but manager said sorry I was past the 60 day warranty and anti scratch doesnt mean they wont get scratched. I emailed corporate and they sent my email to the same manager at Walmart. Great help that was.I felt the need to warn others. Go to Costco or Stanton Optical. Do not waste your money at Walmart optical!
