What Is 3-Zone Progressive Design in Multifocal Contact Lenses?

The proprietary 3-Zone Progressive Design™ by Bausch + Lomb allows for a predictable, quick fit and ensures clear vision across the entire range of visual fields. It is currently found in Bausch + Lomb ULTRA® for Presbyopia and Biotrue® ONEday for Presbyopia.

What Is 3-Zone Progressive Design?

Presbyopia is a natural condition that happens to most people as they age, usually around their mid-40s. It occurs when the lens of the eye becomes less flexible, making it harder to focus on nearby objects and do close-up tasks, like reading and using a computer. This is why people with presbyopia tend to hold things farther away to see them clearly.

Due to the nature of presbyopia, correcting it calls for a lens design with different prescriptions for near, intermediate, and distance vision. Ideally, those prescriptions seamlessly transition into each other for clear, uninterrupted vision.

Bausch + Lomb’s 3-Zone Progressive Design promises to meet those requirements. The design is distinguished by large areas of consistent focusing power in the near, intermediate, and distance zones. The design provides wearers with real-world visual clarity and seamless transitions between the three zones.

How Do Multifocal Contact Lenses Work?

3-Zone Progressive Design sets apart Bausch + Lomb’s multifocal lens offerings from other multifocal lenses.

Multifocal lenses are contacts with multiple prescriptions in one lens to target near, intermediate, and distance vision. This helps people with presbyopia see clearly at any distance.

Multifocal lenses are made with soft and rigid gas-permeable materials, but soft multifocal lenses are more popular because they provide wearers with better initial comfort.

Multifocal contact lenses come in one of two designs: simultaneous and segmented.

  • Simultaneous – In multifocal lenses with a simultaneous design, different zones of the lens are allocated for far, near, and intermediate vision. The wearer determines which region(s) of the lens provide the sharpest vision, depending on the object being viewed.
  • Segmented – In multifocal lenses with a segmented design, the lens has separate zones for distance and near vision. The distance zone is typically found in the upper and central areas of the lens, while the near zone is in the lower half.

Contact Lenses With 3-Zone Progressive Design

The proprietary Bausch + Lomb 3-Zone Progressive Design was first introduced in 2016 as part of the release of the manufacturer’s new multifocal ULTRA lenses. The design is also found in Biotrue ONEday for Presbyopia.

1. Bausch + Lomb ULTRA for Presbyopia

Bausch + Lomb ULTRA for Presbyopia provides clarity in real-world experiences. Featuring exclusive MoistureSeal® Technology, this lens provides long-lasting hydration to keep eyes feeling fresh and healthy.

Bausch + Lomb ULTRA for Presbyopia is a monthly replacement lens designed for daily wear and up to seven days of extended wear. As a silicone hydrogel lens, it supports a healthy wearing experience by allowing optimal levels of oxygen to reach the eye.

2. Biotrue ONEday for Presbyopia

Aside from 3-Zone Progressive Design, Biotrue ONEday for Presbyopia uses proven High Definition Optics to provide wearers with crisp, clear vision, even in low-light conditions.

With 78% water content, Biotrue ONEday for Presbyopia has the same level of moisture as the cornea (the clear tissue covering the front of your eye). That moisture is infused into the lens, so it doesn’t evaporate over your day.

Made with unique HyperGel™ material, Biotrue ONEday for Presbyopia maintains nearly all of its moisture content for up to 16 hours while allowing oxygen to reach the eye.
