I can't say as to how the therapy should or should not work but I do think that if the glasses are for up close work only then they should only be worn then. They should not be worn all day at all. They are used at the computer, reading a book, writing an a journal, etc...they do not do anything for them when it comes to daily activities. They could actually hurt more to wear them if they are not doing the up close work.
The vision therapy that we did with my grandson was a pair of glasses like Nicholas Cage found in the National Treasure movie. They had lenses that flipped up and down, around from one eye to the other, all sorts of pages were to be read with the lenses changing to teach their eyes to interpret what they are reading differently. They are re-training the brain to receive the material the eye is seeing and sending to the brain.
That is the only eye therapy we have any experience with.
Unless the doc says this child is disabled and is not able to function in a normal classroom setting the school should not have any part of this. It would fall to you to pay for this I believe. I could certainly be wrong though. I am under the impression that unless there is a diagnosed life long disability diagnosis the school doesn't even have to help in any way.
I hope I am wrong though...good luck finding out from the insurance how to go about getting help to pay for this.
All our insurance that I know about pays for it just like they would any other vision care for kids. It's covered on their insurance.
