Hi thanks for the advice I have seen an opthamologist had numerous tests done no explanation to symptoms.
I have had MRI scans done they where clear.
My eye tests which I have regular are always perfect.
The episodes also can happen during the day, but every morning my vision is blurred on waking, I can only describe a strange feeling with my eyes and then it passes.
The possible causes are quite numerous. Where should I begin? This could be something as simple as needing glasses or dry eyes to something like cataracts, corneal disease, retinal disease, etc, etc. We know you have blurred vision worse in the mornings and at night. I would begin with a very complete eye exam with an ophthalmologist then take it from there. Good Luck.
