I made an appt with the Optometrist and finally got my glasses. I cannot see through the left lense. My eyes were checked by a student and she did not write down my prescription correctly. I do not appreciate not being able to see a real doc. Waste of time and money.
I have called the customer service line MULTIPLE times and only get voicemail. I left them my name and number last week and haven't got a call back. Disappointed. I will just get a pair from my local clinic.
