Not always / there are some vision problems like mine that are not 100% correctable....
My dominant eye / I have a "lazy" muscle ....and my vision blurrs out / and it comes and goes. Uncorrected I'm about 20/350 (one step from a dog leading me around) --- and they've put some additional prism's in my bifoculs / and DeCot HyWyd has done the same thing in my shooting glasses ... but it still isn't 100% / still blurs out during a round ..... 2 different fancy opthamologists have said the same thing / but good news it probably won't get any worse... Its correctable pretty well for a fixed focul length, like in my office, on my computer ... but not so good out in the world shooting, driving ..stuff like that. If I move my head to the side a little / it often clears up ( but can't do that on a mounted shotgun stock very well ) ...
But there are folks with real health issues - / blurry vision isn't so bad ... its kind of entertaining when a target blurs into a big fuzzy streak / or into 8 or 10 targets ... But heck, even my bad days are Great !
