The doctors and staff were very nice. I gave it 2 stars because I told the staff many times I needed anti blue light coating for my daughter's prescription glasses and they kept saying the coating they chose can block all the lights including blue light. However when I received the glasses and tested them at home, they DO NOT block blue light at all. Very very disappointed! ... I just have not got time to send them back. They need to be more professional and know what they are doing!
