If you are over 40 and need reading glasses on top of your distance prescription, your optometrist will likely recommend either progressive or bifocal lenses. Here is an honest comparison.

What Are Bifocal Lenses?

Bifocal lenses have two distinct zones separated by a visible line: the upper zone for distance vision and the lower zone for near vision. They have been used for over 200 years and are extremely reliable for people who need clear distance and near vision without intermediate range.

Pros of Bifocals

  • Clear, distinct zones — no adjustment period for most wearers
  • Less expensive than progressives
  • Excellent for tasks requiring frequent switching between near and far (e.g., watching TV while reading)

Cons of Bifocals

  • Visible line can be aesthetically unappealing
  • No intermediate vision correction (e.g., computer distance — roughly 60cm)
  • The "image jump" at the line can be disorienting

What Are Progressive Lenses?

Progressive lenses (also called varifocals) provide a gradual transition from distance vision at the top to near vision at the bottom, with intermediate vision in between. There is no visible line. They are designed to mimic natural, youthful vision.

Pros of Progressives

  • Three focal zones in one lens — distance, intermediate (computer), and near
  • No visible line — more aesthetically pleasing
  • Ideal for computer users and those with active, varied daily tasks
  • More natural vision experience

Cons of Progressives

  • Require an adaptation period (1–2 weeks for most people)
  • Peripheral distortion in the lower corners of the lens
  • More expensive than bifocals
  • Premium quality progressives (Varilux, Zeiss) significantly outperform budget versions
The most common mistake is buying budget progressive lenses. Poor-quality progressives have very narrow corridors and severe peripheral distortion — this is why some people give up on them. Premium progressives are night-and-day different.

Which Should You Choose?

Choose bifocals if: You mainly switch between watching TV and reading. You are on a budget. You do not use a computer extensively. You want a no-fuss, proven solution.

Choose progressives if: You use a computer regularly. You want a seamless look without a visible line. You have an active lifestyle with varied visual demands.
