I feel lights very brighter from last few days. I also had the same thing in April and I did brain mri that time and it was normal. And this thing went away on its own. And now It came back and I went to eye doctor he said my eyes are normal. And I just have dry eyes or glare. He gave me a dry eyes drop and a supplement omega sure plus. Please help is it something serious. Brain mri and eye test normal. Vision also normal.
