Instead of providing just two lens powers like bifocals (or three, like trifocals), progressive lenses are true multifocal lenses that provide a smooth, seamless progression of many lens powers for clear vision across the room, up close and at all distances in between.

They have the same focal power throughout the entire lens and can be used to correct farsightedness, nearsightedness, astigmatism, or a combination. This could be for distance, intermediate (computer), or near (reading) vision.
