What is the difference between bifocal and progressive lenses?
The differences between bifocal and progressive lenses are in their function and physical appearance. Bifocal lenses are used for distance and reading. Their key characteristics are that they have a half moon shape on the lower half of the lens that you look into for reading. Progressive lenses allow you to see far, intermediate, and near distances. There are no physical lines on the lenses that separate each area, but instead they blend everything smoothly to look like a single vision lens. Progressive lenses are aesthetically more appealing to most multifocal users.
