This is absolutely real. My son had real reading problems, both Hebrew and English. He kept telling us that his eyes were tired after trying to read for one or two minutes. We were sure he was just lazy. It was affecting all his studies big time.
If you are in the NYC area go to Dr. Greenberg in Perl River. he will give you an honest evaluation. My insurance covered most of it. It takes weeks and weeks, but there was a DRAMATIC improvement in his studies and reading.
The regular MDs dont like to admit anything non surgical or pharmaceutical works. But this is real.
