What is the difference between single vision and progressive lenses?

Single vision and progressive lenses serve different purposes in the world of prescription eyewear. Single vision lenses are designed to provide a single optical prescription across the entire lens surface. They are ideal for individuals who require correction for either distance vision or near vision, but not both at the same time. For example, someone who is nearsighted may use single vision lenses to see clearly at a distance, while someone who is farsighted might use them to read comfortably. On the other hand, progressive lenses are multifocal lenses that provide a seamless transition between multiple vision prescriptions without the visible lines that characterize traditional bifocals or trifocals. These lenses incorporate three different vision zones: the top section for distance vision, the middle section for intermediate vision, and the bottom section for near vision. This makes progressive lenses particularly beneficial for individuals who have presbyopia, a condition that typically arises with age, making it difficult to focus on close objects. In summary, the key difference lies in their functionality: single vision lenses cater to one specific vision requirement, while progressive lenses offer a versatile solution for varying visual needs without interruption.
