What are Multifocal Contact Lenses? And how do they Work?
7th Nov 2024
Multifocal contact lenses are designed to help people with presbyopia, a condition that affects the ability of the eye to focus on objects up close. Unlike single-vision contacts, which only have one prescription strength, multifocal lenses have multiple prescriptions that are layered on top of each other. This allows the wearer to see objects at different distances.

How do multifocal contact lenses work?
The way that multifocal contact lenses work is by using a technology called "simultaneous vision," which allows the eye to focus on multiple distances at the same time. This is accomplished by creating two or more prescription powers in the lens, with each power focused on a different distance.
What are the types of multifocal contact lenses?
There are two main types of multifocal contact lenses: alternating vision lenses and simultaneous vision lenses.
1. Alternating vision lenses
Also known as “alternating bifocal” lenses, these are designed with a line between two prescription zones. This setup allows your eyes to switch prescriptions as you look through different parts of the lens. When you look down to read, you use the near-vision area; looking straight ahead engages the distance vision.
Alternating vision multifocal lenses are designed to allow the wearer to switch between two different powers as their pupil moves up and down. A dividing line in the lens usually helps the wearer know which part of the lens to use for different tasks. For example, when looking straight ahead at a distance, the wearer would use the distance prescription power, but when looking down to read or do other close-up work, they would switch to the near prescription power. This allows the wearer to see clearly at multiple distances.
2. Simultaneous vision lenses
These allow wearers to see clearly at multiple distances simultaneously. These lenses are designed with two or more prescriptions layered on top of each other, with each power focused on a different distance. As the wearer looks at different objects, their brain must learn to adjust to the varying powers of the lens, which may take some time to get used to. However, with regular use, the brain will become more adept at using the lenses and the wearer will be able to see clearly at multiple distances. Simultaneous vision lenses are available in aspheric or concentric ring designs.
Aspheric multifocal simultaneous vision lenses are designed to blend the different strengths together across the lens, resulting in a smooth, progressive change from the distance prescription power to the near prescription power. This allows the wearer to see clearly at multiple distances without the need for a dividing line in the lens.
Concentric ring multifocal simultaneous vision lenses are made up of multiple rings with different strengths, arranged in an alternating pattern. The rings with the distance prescription power are positioned around the center of the lens, while the rings with the near prescription power are positioned around the outer edge of the lens.
Multifocal contacts: Astigmatism, Dry eyes & Daily Use
In addition to alternating and simultaneous designs, you’ll find other variations depending on your lifestyle and vision needs. Here’s a quick breakdown:
Multifocal contacts for Astigmatism
If you have astigmatism, multifocal lenses with a “toric” design can correct both astigmatism and presbyopia. Toric multifocal lenses are shaped to account for the unique curvature of the eye, combining astigmatism correction with multifocal functionality. This option is ideal for those with both conditions and looking to avoid bifocal glasses.
Daily Multifocal contacts
For people who prefer convenience and a fresh lens every day, daily multifocal contacts offer a simple solution. They’re designed for one-time use, so there’s no cleaning routine or storage involved—just open a fresh pair each day. Ideal for people with busy lifestyles or those prone to dry eyes, as daily disposables are typically made from moisture-rich materials.
Multifocal contacts for Dry Eyes
For those with dry or sensitive eyes, certain multifocal contacts are designed with moisture-retaining materials like silicone hydrogel. These materials allow more oxygen to reach the eye, preventing dryness and discomfort. Look for products designed specifically to address dryness, such as Acuvue Moist or Dailies Total1.
