What’s the Difference Between Single Vision, Bifocal, and Progressive Lenses?

When it comes to choosing the right eyeglass lenses, understanding your options can make all the difference in achieving comfortable and clear vision. If you’ve ever wondered what separates single vision, bifocal, and progressive lenses, this guide from Radiant Optometry in Bellflower, CA breaks it all down in simple terms.

Whether you need glasses for reading, driving, or seeing clearly at all distances, knowing which lens type fits your lifestyle can help you see your best every day

Single Vision Lenses

Single vision lenses are the most common type. They contain one consistent prescription throughout the entire lens. That means they correct a single visual issue—such as nearsightedness (myopia), farsightedness (hyperopia), or astigmatism

They’re perfect for:

• People under 40 who have not yet experienced age-related near-vision difficulties.

•  Tasks requiring focus at one distance, like reading or driving.

 

Pros: Simple, affordable, and easy to get used to. Cons: Only correct vision at one distance—many adults end up needing multiple pairs of glasses for different activities.
 

Bifocal Lenses

Bifocal lenses have two distinct optical zones separated by a visible line—one for distance and one for near vision. The upper part helps you see far away, while the lower segment helps with close-up tasks like reading.

They are ideal for people with presbyopia, a common condition that develops with age, making it harder to focus on nearby objects.


Pros:

• Convenient for those needing both near and distance correction.

• Less expensive than progressives.

 

Cons:

• The visible segment line can be distracting.

• Intermediate vision (like computer work) may still appear blurry.

• Some users experience an “image jump” when shifting their eyes between zones.

Progressive Lenses

Progressive lenses—often called no-line bifocals—offer the most advanced and natural form of vision correction. Instead of two separate prescriptions, progressives have a smooth transition from distance to intermediate to near vision, with no visible line.

This design allows clearer vision at every distance—whether you’re driving, reading, or using your phone.

Pros:

• Seamless and natural viewing experience.

• A more youthful look—no visible lens lines.

• Perfect for multitasking or people constantly switching focus distances.

 

Cons:

• Typically more expensive.
• Might require a few days to adapt to the new lens zones
