welcome to the group,
glad you got a second opinion, i had some frontal lobe seizures and came to realize it wasn't sleep related but that my mind couldn't process the information being thrown at me as fast as it was being given to me. basically brain overload on trying to process to much to quickly, my daughter bought me some sunglasses that cut the glare coming in from the sides which helped with not the eyestrain but mad my outside time much better. not sure if anything here helped , but i am hoping you have a blessed day.
