Alright Boomer-

I did a little book relearnin' for you. I will run down a list of the differential causes and whether I think you should research yourself online about them to discuss it with your Doc or just ignore because it isn't your problem...

I went through a bunch of common causes for blurred vision... I ruled out brain tumor, CVA(stroke), amaurosis fugax, cataract, concussion, conjunctivitis, corneal abrasion, corneal foreign body, diabetic neuropathy, dislocated lens, eye tumor, hereditary corneal dystrophies, hypertension, hyphema, iritis, migraines, multiple sclerosis, optic neuritis, retinal detachment, retinal vein occlusion, senile macular degeneration, serous retinopathy, temporal arteritis, uveitis, and vitreous hemmorage based on the symptoms history you listed.
I only found one other major likelyhood(besides my post on NLD blockage) that seems to fit your description:

Glaucoma- One of the specific types of Glaucoma causes transient visual blurring and/or halo vision which may may precede pain and eventual blindness. [/u] Still unlikely with your symptoms (and after a check) but I think I would make sure he did an accurate glaucoma check as it does fit slightly into your history.

Other than that, several meds can cause your symptoms as well including antihistamines.

Unless you tell me you have diplopia ( double vision), "floaters" in your vision, or have been experiencing a chronic/progressive loss of vision on the recent year or so then that is about all I can come up with. That about does it for me. I hope it was helpful. At least you now have three different things to harass your doc with now. Good luck
