What would cause, spots/cloudiness in the eye, shadows around written text in books, and ringing in ears? Sometimes headaches

I. I can't think of a single common entity that would cause all three of these at the same time. They may be unrelated. A full ophthalmic exam by your ophthalmologist is warrented.
You. You may actually want to start with your regular doctor, or a neurologist. With multiple symptoms, affecting different systems, the answer may not be in your eye.
It. It could be a form of migraine headache. I recommend a full evaluation by a neuro-ophthalmologist.
