Multifocal contacts are a type of contact lens designed to offer clear vision at multiple distances. They work by incorporating different optical powers into a single lens, allowing the wearer to see both nearby objects and those at a distance without needing to switch between multiple pairs of glasses or contacts. These lenses are carefully crafted with various zones, each with a different visual correction power. For instance, the central part of the lens corrects vision for nearby objects, while the outer zones assist in seeing things farther away. So, when you wear these contacts, your eyes can smoothly transition between different visual distances, providing a seamless and convenient experience for people with presbyopia or other age-related vision issues.
An overview of multifocal contacts
Multifocal contacts are a type of contact lens that is designed to correct vision at multiple distances. Unlike traditional contact lenses, which only correct vision for one distance, multifocal contacts allow wearers to see clearly both near and far.
These lenses are particularly useful for individuals who have presbyopia, a condition that typically occurs with age and causes a gradual loss of near vision. Presbyopia makes it difficult to focus on objects up close, such as reading a book or using a smartphone.
Multifocal contacts work by using different zones or rings on the lens surface, each with a different prescription. These zones are strategically placed to correct vision at different distances. For example, the central zone of the lens may be designed for clear distance vision, while the outer zones are for near vision.
Understanding the different designs of multifocal contacts
When it comes to multifocal contacts, there are several different design options available. These designs are specifically created to address the varying vision needs of individuals who require multifocal correction. Here, we will explore three common designs: simultaneous vision, concentric ring, and aspheric designs.
Simultaneous vision design
The simultaneous vision design is the most common type of multifocal contact lens. This design incorporates multiple prescription powers into a single lens, allowing different distances to be seen clearly at the same time. In this design, the eye automatically adjusts its focus to the appropriate power for near, intermediate, or distance vision. This simultaneous vision design is typically achieved using either concentric or aspheric rings.
Concentric ring design
The concentric ring design involves placing multiple rings of different prescription powers on the surface of the contact lens. Each ring has a specific distance power, and as the pupil moves, it aligns with the appropriate ring for clear vision. The center of the lens usually provides distance vision, while the outer rings cater to near or intermediate vision. This design allows for a smooth transition between different distances, providing clear vision at various focal points.
One potential downside of the concentric ring design is that it may cause glare or halos around lights, particularly in low-light conditions. This can be attributed to the abrupt transition between different powers in the rings. However, many individuals adapt to this effect over time, and it becomes less noticeable.
Aspheric design
The aspheric design differs from the concentric ring design as it does not rely on distinct rings of different powers. Instead, it uses a gradual change in prescription across the lens surface, providing a more natural and continuous transition of vision. This design is particularly beneficial for individuals who require both near and intermediate vision correction, as it allows for more precise focusing at different distances.
The aspheric design also minimizes the impact of glare and halos, making it a preferable choice for those who frequently drive at night or spend time in low-light environments. Additionally, the aspheric design can provide better peripheral vision, as there are no distinct rings to restrict the field of view.
- Simultaneous vision design incorporates multiple prescription powers into a single lens, allowing different distances to be seen clearly at the same time.
- The concentric ring design uses multiple rings of different powers to provide clear vision at various focal points.
- The aspheric design utilizes a gradual change in prescription across the lens surface for a more natural and continuous transition of vision.
Pros and cons of multifocal contacts compared to traditional contact lenses

4. Potential for adaptation period and visual compromises
While there are numerous benefits to multifocal contacts, it’s important to acknowledge that some wearers may experience an adaptation period when first switching from traditional contact lenses. Adjusting to the multifocal design and different lens powers of these contacts may take some time, and wearers may initially notice slight differences in visual acuity or depth perception.
Furthermore, it’s essential to recognize that multifocal contacts are a compromise between different visual distances. This means that wearers may not achieve the same level of clarity and sharpness as they would with single-focus lenses specifically designed for a particular distance. However, for many individuals, the convenience and versatility offered by multifocal contacts outweigh these slight compromises in visual acuity.
How do multifocal contacts correct presbyopia?
Multifocal contacts are designed to correct presbyopia, a condition that typically occurs around the age of 40 and affects the ability to focus on close objects.
Traditional contact lenses, such as monovision lenses, are designed to correct either nearsightedness or farsightedness, but not both. This means that people with presbyopia often need to wear reading glasses in addition to their contact lenses in order to see clearly at different distances.
Multifocal contacts, on the other hand, are specifically designed to correct both near and distance vision, making them a convenient option for people with presbyopia. These contacts have multiple lens powers within each lens, allowing for clear vision at different distances without the need for reading glasses.
| Types of multifocal contacts: | Description: |
|---|---|
| Simultaneous vision designs | These contacts have different lens powers distributed across the lens, with the near and far lens powers in the same area of the lens. This allows the eyes to simultaneously focus on near and far objects, providing clear vision at multiple distances. |
| Asymmetric designs | These contacts have different lens powers distributed across the lens, with the near and far powers in different areas of the lens. This allows the eyes to use the appropriate lens power for the desired distance, providing clear vision at different distances. |
| Concentric designs | These contacts have multiple rings of lens powers, with the near lens powers in the center of the lens and the distance powers on the outer rings. This allows the eyes to use the appropriate lens power for the desired distance, providing clear vision at different distances. |
Multifocal contacts work by allowing the eyes to simultaneously focus on near and far objects, which helps to correct presbyopia. The brain learns to interpret the different lens powers within the contacts and adjusts the focus accordingly, providing clear vision at different distances.
