What is the difference between bifocal and progressive lenses?

Bifocal lenses are designed with two distinct optical powers, typically one for distance vision and another for near vision. This is achieved by incorporating a visible line that separates the two areas. When a person looks through the top part of the lens, they can see far away, while the bottom part allows them to focus on objects up close.

Progressive lenses, on the other hand, provide a smooth transition between multiple focal lengths, allowing the wearer to see at various distances without the visible line found in bifocals. This gradient of optical power means that wearers can seamlessly shift their gaze from near to intermediate and then to far distances, mimicking the natural eyesight of individuals without prescriptions.

Understanding this distinction is crucial for customers who may have specific needs regarding their vision correction. Bifocals may suit those who primarily need help with two specific activities, while progressives offer a more versatile solution for those who engage in various tasks at different distances.
