Progressive or Bifocal? Here's the Actual Difference

Need correction for more than one field of vision — reading and distance, say? You've probably run into two options: bifocals and progressives. Both correct multiple prescriptions in a single lens, but the mechanics are pretty different.

Bifocal lenses

Bifocals have two distinct zones: a larger area for distance and a smaller segment, usually at the bottom, for reading and other near work. You can typically see the line separating them.

Pros:

• Usually less expensive than progressives
• Wide, clearly defined reading zone
• Easier adjustment period for some wearers

Cons:

• Visible line across the lens
• Only two prescriptions — no help for mid-range vision, like a computer screen
• An abrupt "jump" in the image as your eye crosses the line

Progressive lenses

Progressives blend near, mid-range, and distance prescriptions into one lens with no visible line — the correction shifts gradually as your eye moves down the lens.

Pros:

• No visible line — looks like a standard single-vision lens
• Smooth transition between distance, computer, and reading vision
• Covers the full range of vision, not just two zones

Cons:

• Narrower zones take some getting used to before you find the "sweet spot"
• Slightly more expensive than bifocals
• A one-to-two-week adjustment period is common for new wearers

Which one's right for you?

Spend a lot of time on a screen on top of reading and driving? Progressives usually feel more natural, since they correct for that mid-range distance too. If budget's the deciding factor, or you've worn bifocals comfortably for years, sticking with them is a perfectly reasonable call.

Our opticians will walk you through both based on your prescription, lifestyle, and budget.
