Hi Twink - Whoops - I just typed a reply and somehow managed to lose it, so my apologies if this is a repeat reply. I also have occasional blurry vision, and do have mild ON, but also have (and have had for years) a cataract that is slowly progressing. I went to the opthalmologist the other day, told him of recent increase in blurriness and focusing, which is resolving presently, but I know it could come back later. He checked, thinks the cataract is the culprit - a relief to me. We'll talk about cataract removal later this year, but in the meantime, I'm happy to think that the cataract is something common that can be dealt with. I wish for you the same.
