I think that is wonderful that they had another surgical option, with stents. And that the first one was done satisfactorily, already. I'll remember that. God only knows if I'll end up having to go with that option someday, too. Also, that your ins ended up covering it 100%. As far as the question about vision changes signaling eye problems. In many cases, yes. But not all. For instance, I've had floaters since I was maybe 13, and so far, since I got used to them early I only think about them when the eye doctors office asks me if I have any. But many other vision changes did mean I needed medical help for them. I began going nearsighted at age 7 and it's progressed now to where I'd be wearing those "coke bottom bottle" lens if high index ultra thin prescription lens hadn't been invented. I began seeing double and it's a cranial nerve that was damaged sometime since birth. They can put invisible prisms in glasses lenses to correct it, and later do a surgery too. That's really wonderul how your glaucoma is being taken care of without financial harm to you.
