I ve been wearing glasses since I was 4 years old. I m 23 now and they have never messed up my prescription or have had to do my prescription twice. I went in for an appointment 5/19, got my prescription taken(sat for 3 hours), and picked out my frames. Ended up paying 300$ because I m very blind. Only took a week (5/26)to receive them which was great. I go to pick them up and when I put them on I couldn t see. I call right after picking them up and have to schedule another visit. My new glasses had lower prescription then my current glasses. I asked for a refund because I would rather go somewhere else. Now I have to wait 2-6 weeks to receive my refund by mail even though I paid with a card.
