After strong eye inflamation I still see blur. Will it last like that forever? My doctor said inflamation is healed but I see blur even half year after

Uveitis? Depends were you had inflammation. Sometimes cornea develops opacity, cataract can develop. Posterior uveitis can cause ischemia of the retina, strokes and commonly macula edema. You might want to see a specialist in uveitis, most commonly they practice in a university practice.
Blurry Vision. I hate to say this, but there is more than one single eye doctor in the United States. I would recommend a 2nd opinion from an ophthalmologist. If they have the same response, you might want to ask your primary doctor to evaluate you for other possible causes. Hope this helps to steer you in the right direction.
