I made my own. Using a pair of dark tinted, polarized Cocoons®, it was easy to add on a pair of ThinOptics® plastic, flexible magnifiers by simply supergluing them to the nasal bridge as shown. I now have some very functional, polarized fly fishing glasses with lateral sun screens which you can even wear over your prescription glasses if desired. I can even tie on #22 flies.
The Cocoons® you can buy at any Cabelas store or online for $49.99. The ThinOptics® magnifiers you can buy online for $19.95. The later comes with a spare pair and have a very thin case which can be attached to the back of your cell phone case. The super glue I prefer for attaching the magnifiers to the sunglasses, and also use on my flies from time to time, is Loctite®. PS-the Cocoons® also have a really nice carrying case as well which can clip to your pants, Idaho fly fishing vest or Idaho fly fishing chest pack.
PS - In my opinion, glasses such as these have magnifiers which are too small.-->
