Since you have not gotten a response, I will attempt it based on the information I have been given in regard to my dd7. She has seen an Ophthalmologist and two behavioral Optometrists.
DD is a good reader and never really complained about not being able to see things far away or up close. It was not until she began 1st grade this fall that the teacher mentioned that she thought dd may not be seeing the board and this may be contributing to her inability to stay with tasks requiring her to see the board.
We immediately took her to the Ophthalmologist who prescribed "reading glasses"...saying they may help, they may not! Given that she exhibited other education related issues we were led to a Behavioral Optometrist, who said that the glasses offered no assistance to her. (We didn't care for this guy for a number of reasons-that would be a novel length post) We took her to another Behavioral Optometrist recently and she indicated that the glasses do help. Her testing included computer read outs of exactly what dds eyes were doing as she was reading. It gave us some quantitative results that supported the Dr's recommendations.
Anyway, I guess the bottom line is to do some research and perhaps get a second opinion. Include in your research information on the Doctor and if possible the types of testing the Doctor is capable of doing. IF you can, check out the office before you take your dd to the appointment. Also gather any and all information on child and your questions.
Good Luck!!
