I use the ICE Eyeshield - ESS Products - ESS Eye Pro - Ballistic Goggles - Ballistic Sunglasses - Military Eyewear - Eye Protection – Shooting Glasses with the Rx insert. I wear bifocals, with the lower for close-up reading and the upper for computer distance; and the computer distance is also right at pistol front sight distance. Using a rifle, the front sight is just a little bit fuzzy, and since I shoot mostly cowboy, the targets are easy to see. -- Grizhicks
