Presbyond: near, intermediate and far vision, how does it achieve this?

22 January 2026

Presbyopia is a natural age-related condition that makes everyday activities—such as reading your phone, using a computer, or looking at a restaurant menu—more challenging.

For many years, the most common solution has been reading glasses or progressive lenses. Today, thanks to advances in laser surgery, there is a more advanced alternative available to you: Presbyond.

One of the most frequently asked questions is: How is it possible to see clearly at near, intermediate, and far distances without glasses?

What is Presbyond?

Presbyond is a laser treatment developed by the prestigious German company ZEISS to correct presbyopia. It is not a traditional monovision approach, but rather a more sophisticated and personalized solution designed to provide balanced, functional vision at all three distances.

Presbyond is based on three main pillars:

1. Optimized micromonovision

Unlike conventional monovision—where one eye is clearly set for distance and the other for near vision—Presbyond creates a very small, carefully calculated difference between both eyes.

• One eye is slightly optimized for distance vision

• The other is slightly optimized for near vision

• Both eyes maintain excellent intermediate vision

This difference is so subtle that the brain can adapt naturally.

2. Visual fusion zone

The treatment creates what is known as a fusion zone, where the brain combines information from both eyes to provide continuous vision.

This allows patients to:

• Read up close

• Use screens and computers comfortably

• See clearly at distance

…without noticeable jumps, disturbing blur, or constant dependence on glasses.

3. Brain adaptation (neuroadaptation)

Our brain is more flexible than we often realize. After Presbyond, the visual system learns to automatically select the sharpest image depending on the viewing distance.

This adaptation process is:

• Gradual

• Natural

• Different for each patient
