I use Decot Hy-Wyd bifocals and settled on the following configuration with the help of Robert from Decot. My bifocal is a 2.50, they brought .75 of that up into the main part of the lens to bring the handgun front sight into focus. This for me was not enough to disturb the long distance focus (barely noticeable). The bifocal line was placed low enough so as not to be in the way for any activities other than close up reading, etc.. I initially started with .25 in the main part of the lens and that was not enough and didn't last long. the bifocal still remains a 2.5 overall. The light rose color works well all around for me. Hope this helps.
