Progressive lenses (frequently called no-line bifocals) offer vision correction through an aspheric design where curvature (and focusing power) gradually changes from the top of the lens to the bottom. There is no abrupt change in the lenses; there is no visible dividing line that has always posed difficulty for many people with bifocals. This design allows you the freedom to look through your lenses and see up close and far away without having to adjust. Modern progressive lenses offer outstanding clarity and comfort for seeing at all distances.
Next time you see your doctor and update your glasses, find out if progressive lenses might be right for you.
