In this guide, we explore the IOL choices that have proven effective in reducing glare and halos, explain how these lenses work, and share insights on selecting the best option for your unique visual needs. Read on to learn about the technologies that are transforming outcomes in cataract surgery, and please feel free to call our office for personalized guidance.
Glare and halos are common complaints after cataract surgery, particularly with certain lens designs. These visual disturbances occur when stray light is scattered by the implanted lens, creating a ring or halo around bright lights. Although traditional multifocal designs have helped many achieve greater spectacle independence, they have historically come with a higher risk of glare-related side effects. Fortunately, recent advancements have focused on refining these designs and developing new models that minimize such symptoms.
Here’s the thing: reducing glare and halos isn’t only about enhancing the clarity of your vision—it’s also about improving your overall quality of life. Patients who experience fewer visual disturbances enjoy more comfortable night driving, better contrast in low-light situations, and an overall more natural visual experience.
Monofocal IOLs have long been the gold standard in cataract surgery. They are designed to focus at one distance—commonly for distance vision—providing excellent image clarity and contrast sensitivity. One of the huge benefits of monofocal lenses is their minimal interference with light transmission, which means that glare and halos are rarely a problem. While patients may still need glasses for near activities, a monofocal lens is a tried-and-true option for those who prioritize crisp, predictable vision.
Advantages of monofocal IOLs include:
Because they transmit light in one focus, monofocals reduce unwanted light scattering.
Patients report sharp, clear images with a natural quality.
With well-established safety records, these lenses offer consistent performance.
For individuals whose main goal is to achieve the best possible distance vision and who are comfortable using reading glasses for close work, monofocal IOLs remain a dependable choice.
Multifocal IOLs are designed to offer multiple focal points, which can reduce the need for glasses for both near and far tasks. Historically, however, their design—especially when using diffractive optics—led to side effects such as halos, glare, and starbursts around bright lights. These issues arise because the lens splits light into more than one focal point, sometimes resulting in slightly less contrast.
Despite these challenges, improved multifocal options have been developed with careful attention to minimizing dysphotopsias. For example, the newer trifocal lenses have demonstrated a lower incidence of glare and halos compared to older bifocal designs. When a patient’s lifestyle calls for clear vision at multiple distances, and they are willing to accept a modest risk of mild disturbances, multifocal IOLs can be highly effective.
Some key points with multifocal lenses include:
Trifocal designs target near, intermediate, and distance, with smoother transitions between the ranges.
Studies show high levels of spectacle independence, with many patients experiencing fewer visual disturbances with the latest models.
Advances in diffractive and refractive technology have reduced the overall side effect profile compared to earlier iterations.
EDOF lenses represent an exciting innovation in cataract surgery technology. Instead of splitting light into discrete focal points, EDOF lenses elongate the focus into a continuous range. This approach offers excellent intermediate and distance vision with visual performance comparable to monofocals while reducing the common side effects of multifocal lenses.
What makes EDOF lenses particularly appealing is their ability to provide a broader functional range of vision—often with fewer disturbances. Many patients report having better quality vision in dim light conditions, a crucial factor for night driving and low-light environments.
Notable features of EDOF lenses include:
Certain EDOF lenses use innovative optical principles that avoid splitting light, such as wavefront-shaping technology.
By extending a single focal point, these lenses reduce the interference that creates halos and glare.
Patients who use digital devices or require excellent intermediate vision (such as for computer work) benefit from these lenses’ balanced performance.
For example, the Vivity IOL is noted for its non-diffractive design that minimizes the typical glare and halo effects associated with other premium lenses. By “stretching” the light into an extended focal range, it delivers clear and natural vision even in challenging lighting conditions.
Another breakthrough in modern cataract surgery is the development of adjustable lenses, notably the Light Adjustable Lens (LAL). Made of a photosensitive silicone material, this lens allows post-operative adjustments through painless UV light treatments. With the LAL, patients can fine-tune their refractive outcome after surgery, achieving a customized visual correction that can further minimize glare and halos.
Benefits of the Light Adjustable Lens include:
Adjustments can be performed during the healing process to get as close to the optimal prescription as possible.
Fine-tuning ensures that residual refractive errors, which might contribute to glare, are minimized.
Those who have undergone prior refractive procedures often benefit from the adjustability offered by the LAL.
This innovative approach gives patients more flexibility in achieving their desired vision while gently reducing the risk of photic phenomena like glare and halos.
Monofocal lenses are designed to allow nearly 100% of the light entering the eye to be focused on the retina, reducing scatter and unwanted reflections. This leads to minimal light distortion.
Traditional multifocal lenses use diffractive rings to split light. Newer, non-diffractive designs—used in some EDOF lenses—avoid this splitting, which greatly reduces the chance of halo formation. For example, wavefront-shaping technology in some EDOF lenses directs light smoothly without causing interference patterns.
By elongating the focal range rather than creating multiple fixed focal points, EDOF lenses provide a more continuous vision profile. This means that images are less likely to be disrupted by abrupt changes in focus, which can lead to glare or halo effects.
The ability to adjust the light sensitivity or refractive correction of a lens after surgery (as with the Light Adjustable Lens) allows for fine corrections that further reduce residual visual disturbances.
Your visual needs—whether prioritizing excellent distance vision or balancing intermediate vision—play a crucial role in lens selection. For example, if your daily routines involve night driving or extensive computer work, an EDOF lens might be recommended for its balanced performance and reduced glare.
For patients with retinal issues or corneal irregularities, monofocal and certain EDOF lenses are often preferable, as they tend to produce fewer visual disturbances compared to multifocal lenses.
Multifocal and hybrid lenses offer the promise of reduced dependency on glasses for near tasks. However, if complete elimination of glare is a priority, our cataract surgeons may recommend lenses known for their more predictable light management, such as advanced EDOF options or adjustable lenses.
Patients who have undergone previous refractive procedures like LASIK may benefit from adjustable lenses such as the Light Adjustable Lens, as these allow for precise fine-tuning after the initial surgery.

Monofocal lenses set a single focal point and are renowned for their clarity and minimal incidence of visual disturbances. In contrast, multifocal lenses are designed for multiple focal distances but have traditionally been more associated with glare and halos. Newer multifocal options, especially trifocal lenses, have reduced these issues, yet a small percentage of patients may still experience dysphotopsia. Our cataract surgeons will assess your tolerance for light-based disturbances before suggesting a multifocal approach.
EDOF lenses bridge the gap by offering an extended range of vision without splitting light into distinct zones. Among these, the Vivity IOL stands out. It employs unique wavefront-shaping technology to extend the focal range while keeping visual disturbances at bay. Patients often appreciate the fact that Vivity’s non-diffractive design naturally reduces glare, making it an excellent choice for those sensitive to visual aberrations.
The design ensures excellent contrast even during night driving.
By avoiding light splitting, it minimizes the rings and halos often seen with diffractive optics.
Extended depth of focus provides continuous vision across multiple distances, creating a more natural visual experience.
The Light Adjustable Lens represents another frontier in cataract surgery innovation. It allows tailored adjustments post-surgery, ensuring that the final refractive outcome is as close to perfect as possible. This personalized approach not only improves visual acuity but also minimizes side effects like glare and halos. Particularly for patients with unusual eye measurements or previous refractive surgery, the adjustability offers peace of mind and an added layer of safety against visual disturbances.
The brain gradually adjusts to the patterns of light provided by your new lens. In most cases, the intensity of any halos or glare diminishes over a period of three to six months.
Regular postoperative appointments are crucial. Our cataract surgeons will monitor your healing process and address any concerns, including any persistent glare or halo effects.
For adjustable lenses, multiple review sessions allow for fine-tuning based on your visual feedback, ensuring the best possible final outcome.
Choosing the best lens to reduce glare and halos requires balancing your desire for spectacle independence with your tolerance for potential visual side effects. Whether you spend long hours on digital devices, drive frequently at night, or enjoy outdoor activities, your lifestyle plays a significant role in lens selection.
Preexisting conditions and previous surgeries are factored into the decision—a healthy eye can accommodate a broader range of advanced lens technologies.
Some patients are more sensitive to changes in visual perception. Clear and honest discussions about expected outcomes help set realistic expectations and ensure satisfaction with the final result.
These utilize a small aperture design to filter out peripheral light, thereby increasing depth of focus and reducing halos. Although not yet widely approved in the United States, early studies suggest significant potential for patients with irregular corneas or other complexities.
Combining the benefits of multifocal and monofocal designs, these new lenses are engineered to provide a more continuous visual experience while curbing the unwanted glare that has long been associated with traditional diffractive multifocals.
Ongoing enhancements in light adjustment techniques and wavefront-guided principles continue to push the boundaries of what is possible in cataract surgery, making future IOLs even more adept at addressing glare and halos.
