What is the difference between progressives and bifocals?

Progressive lenses, also known as no-line bifocals or multifocal lenses, and traditional bifocals differ in design and functionality. While both types of lenses are designed to correct vision at different distances, they do so in distinct ways. Bifocals consist of two distinct areas, with the upper section for distant vision and the lower section for close-up vision. The dividing line between the two sections is noticeable. On the other hand, progressive lenses have a seamless transition between distance, intermediate, and close-up vision. This gradual transition makes them a more aesthetically pleasing option, as there is no visible line on the lens. Progressive lenses provide a smoother progression between vision corrections, eliminating the need to switch between different sections like bifocals. Therefore, progressive lenses offer a more natural and comfortable visual experience for those with multiple vision needs.
