Months ago I considered progressives and did some research. The variety of types is dizzying. Apparently Zeiss makes some great ones, if you want to spend several hundred bucks. Somewhere I encountered this bit of advice, which I copied: - - - - - Read this before purchasing Progressive Lenses - - - - - - - - - - There are two large areas of the lens that you cannot see through. Imagine an hourglass. The bulge areas at the bottom and top of the lens are for near and distance vision, and the thinner "corridor" connecting them is for intermediate distances. On either side of the narrow portion of the hourglass objects will appear blurry. Less expensive lenses have a narrower corridor that can restrict the viewing area considerably. And, on smaller lens sizes, it is necessary to slice off a portion of the bottom; the smaller the frame size, the smaller the reading portion of the lens. - - - - - - - - - - Adapting to progressive lenses - - - - - - - - - - You must learn to move your head to see things; you cannot just move your eyes because of the blurry parts of the lens. It is common to experience dizziness and headaches during the time that you are adapting. Some people never adapt. - - - - - The head-movement required for lined bifocals is one thing, But it's easy to manage and adapt to. And I don't mind using computer glasses at my desk and when grocery shopping. Progressives aren't worth the extra trouble and money for me, especially since I've been rear-ended in the car several times and have some neck issues. And I'm not sufficiently vain to want to hide the line. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://www.glassyeyes.com!
