Reader Glasses
what is the difference between progressive lenses and no line bifocals?
my mom has progressive lenses and hates them. she previously wore reader glasses and this is her first pair of “real glasses.” she hates the progressive lens, and is considering taking the glasses back. any suggestions? and also, what is the difference between the progressive lenses and no-line bifocals? thanks.
Progressive lenses have less power at the top edge and maximum power at the bottom edge. The power of the lens increases gradually from top to bottom. The idea is that you can adjust your head so that you are looking through the part of the lens which is just right for the distance of the thing you are looking at. Most people don’t like these at first because it takes a change in the way glasses are used. Older people do not like change. However people who will work with the progressive lenses and learn to use them usually end up liking them.
A no-line bifocal lens is one which does not have a distinct line between the top and the bottom lens. It has a more gradual change from upper to lower, like the progressive, but not totally, it is a compromise between bifocals and progressive lenses.
