Blurred vision

I am a chronic daily headache sufferer, with a supra orbital meningioma. I am 33 years old/male/white.   My last eye exam 1.5 years ago was normal.   I haven't had any blatently obvious vision probs from the meningioma (except sometimes I think I'm getting paranoid and when I cover the opposite eye as the tumor the vision in the tumor sided eye is not blurry but just more "faint"...is that the kind of vision loss description consistant with the a tumor?)    

But that is my history, but here is the thing. Lately I've been getting this fog over my eyes (both eyes).  Other times, it feels like my vision doesn't focus fast enough and fluctuates from good to bad within minutes, in the same blurry was as if you need glasses...or going from a distant to near object it doesn't focus fast enough...that and the fog over my eyes.  When this happens it feels like my eyes are dry or burning and sometimes like a grain of sand is in the eyes.

Can you please elaborate?  And do eye exams cause dry eye? Because I had much more foggy vision after my last eye exam.  Thanks a bunch.

'(except sometimes I think I'm getting paranoid and when I cover the opposite eye as the tumor the vision in the tumor sided eye is not blurry but just more 'faint'...is that the kind of vision loss description consistant with the a tumor?)'

loss of contrast...yes, that i could be from a tumor/the tumor.  its possible.

'Lately I've been getting this fog over my eyes (both eyes).'

dont know.  could be many things.  would need an eye exam to figure this out

'Other times, it feels like my vision doesn't focus fast enough and fluctuates from good to bad within minutes, in the same blurry was as if you need glasses...or going from a distant to near object it doesn't focus fast enough'

this sounds like either 'accommodative infacility' if you are under say 35 years old, and/or emerging 'presbyopia' if you are over 35 years old.  wopuld need reading glasses/bifocals/progressives or multifocal contacts or various surgical procedures (like CK) to fix/solve.  could be related to 'the fog' you mention above:

burning and foreign body sensation (the 'grain of sand' analogy) are the classic symptoms of dry eye.  could be helped by use of artificial tears or lubricant eye drops (not vasoconstrictors like 'original' visine)..  probably UNrelated to  the aforementioned 'fog' or difficulty changing focus.  

eye exams definitely DO NOT cause dry eye or any other malady.
