I have been going to Dr Perez for almost 2 years and I brought my 4 year old in this past week. I was worried that the exam would be too difficult and couldn't be done but we were there for about 2 hours and everything went so smooth. He is very thorough and I feel so relieved now that my daughter has glasses now and this is her first pair. They have a few children frames that are very stylish and priced very reasonable but I do wish that they had more. I'm worried that they might not be very comfortable since they had none of the glasses with the soft flexible tip thingies on them. Regardless, the glasses were ready in 3-4 days and my daughter loves them and that is all that matters.
