Progressives correct near, intermediate and distance in one lens. They have a seamless, invisible design where the power “progressively” changes throughout the lens with distance vision on the top, near vision on the bottom, and intermediate in between.

Bifocal lenses have two viewing areas: a larger viewing area for distance with a smaller area for reading. If you haven`t worn bifocals before, it can take some time to adjust to moving your eyes between the distance and reading portions of the lens.
