I have now reached the point that I need magnifiers for anything smaller than a size 14. I found the Guideline sunglasses that have bifocal magnifiers at the bottom of the lenses, if anyone is or has used them please let me know what you think about them. Here is a link to there web site in case you haven't heard of them before. Thanks http://www.glpolarized.com/Guideline/Bifocal
