I would guess your talking about Progressive lenses. These are some times called "No Line" bifocals, but that name is an oversimplification of how these lenses work. As we age, the lens in our eyes decrease in flexibility. Usually around age 43 in my practice, people become symptomatic and need some help with near vision. This is when a progressive lens would be used so you can see both in the distance (top) and at near (bottom) but also at the computer distance (intermediate) as well. The advantages of progressive lenses include no line, at some point on the lenses any distance should be in focus. So they are pretty handy. The disadvantages are that they are more expensive, but they take about the same amount of "getting used to" as regular bifocals. There are many makes and models of progressive lenses and not all do what you need equally well. Make sure you talk to your doctor or optician about how you use your eyes and which progressive lens would work the best for you. Dr. Dan.
