Multifocal vs. Bifocal: The Best Choices for Presbyopia
Table of Contents
As we age our vision changes and many people develop presbyopia a condition that makes it harder to focus on close objects. To address this multifocal and bifocal contact lenses have become popular solutions. Both types of lenses correct near and far vision but they do so in different ways. Let’s explore the key differences benefits and how to choose the best option for aging eyes.
Multifocal Contact Lenses
Types of Multifocal Lenses
There are two main types of multifocal lenses:
- Simultaneous Vision: These lenses allow you to see at all distances at the same time. The lens blends the powers for distance and near vision.
- Transitional Vision: These lenses use different zones for different distances creating a smooth transition from one focal point to another.
How Multifocal Lenses Work
Multifocal lenses work by providing multiple powers within the same lens. This helps the wearer see clearly at near intermediate and far distances without needing to switch glasses or lenses.
Bifocal Contact Lenses
Types of Bifocal Lenses
Bifocal contact lenses have two distinct zones: one for near vision and one for far vision.
- Concentric Bifocals: The lens is divided into circles with the near vision in the center and distance vision around it.
- Segmented Bifocals: These lenses have a visible line separating the near and far vision zones.
How Bifocal Lenses Work
Bifocal lenses have a clear separation between the near and distance vision areas. When you look through the upper part of the lens you can see far away when you look through the lower part you can focus on close objects.
Pros and Cons
Pros:
- Clear separation of near and distance vision.
- Ideal for people who need clear vision at specific distances.
Cons:
- May take time to adjust to the distinct separation.
- Not ideal for people who need smooth transitions between near, intermediate, and far vision.
How to Use
Insertion and Removal Tips
When using contact lenses always ensure your hands are clean before handling them. To insert gently pull your eyelid open and place the lens on your eye. For removal use your fingers to gently pinch the lens and lift it off.
Care and Maintenance
Proper lens care is crucial to avoid eye infections. Clean and store your lenses in a disinfecting solution and replace them as recommended by your eye care professional.
Differences Between Multifocal and Bifocal Lenses
Visual Transition Differences
Multifocal lenses offer a smooth transition between near and far vision. In contrast bifocal lenses provide a more distinct shift between the two vision zones.

Multifocal lenses have gradual power changes throughout the lens while bifocal lenses have clear divisions for near and far vision.

Pros and Cons for Aging Eyes
Advantages for Near and Far Vision
Multifocal lenses provide the convenience of clear vision at multiple distances eliminating the need to switch between glasses for reading or distance tasks.
Disadvantages and Adjustment Period
It may take time for your eyes to adjust, especially if you are switching from single-vision lenses. Some people also experience blurry vision during the transition phase.
Alternative Options for Presbyopia
Reading Glasses
Reading glasses are an affordable and simple option for presbyopia. However they require you to take them on and off as needed.
Monovision Contacts
Monovision contact lenses involve wearing one contact for near vision and one for distance vision. Some people find it more convenient than bifocals or multifocals.
Surgery Options
Laser surgery such as LASIK can be an option for some people with presbyopia allowing them to regain clear vision without glasses or contacts.3
