Monovision vs. Laser Blended Vision: What’s the Difference?

Posted by  On 11-09-2023

Presbyopia is a visual condition that poses difficulties in focusing on nearby objects and is commonly experienced as individuals grow older. To address this issue, eyeglasses, contact lenses, and traditional multifocal intraocular lenses have been the go-to solutions for many years.

However, recent strides in technology and surgical procedures have introduced more sophisticated alternatives for addressing presbyopia, with two prominent methods taking the spotlight: monovision and laser blended vision.

While both approaches aim to enhance visual acuity, they differ significantly in their methodologies and outcomes. Understanding these distinctions is key for those looking to bid farewell reading glasses and embrace a more natural visual experience.

This article delves into the crucial differences between monovision and the revolutionary PRESBYOND treatment, shedding light on why laser blended vision treatment stands out as the superior choice.

Whether you’re new to the world of vision correction or considering upgrading your existing solution, this article aims to equip you with the knowledge necessary to make an informed decision about your eye health and visual freedom.

Understanding Monovision

Monovision is a traditional approach to correct presbyopia, which is a common age-related condition that reduces the eye’s ability to focus on nearby objects. This technique involves adjusting one eye for distance vision and the other for near vision. The dominant eye is typically corrected for distance vision, while the non-dominant eye is corrected for near vision using contact lenses, intraocular lenses, or laser surgery.

While monovision can be effective for some individuals, it has certain limitations. One notable disadvantage is reduced depth perception and binocular vision, which can lead to difficulties with specific tasks requiring accurate depth perception, such as driving at night or playing sports. Additionally, some patients may find it challenging to adapt to blur differences between the eyes, leading to discomfort and reduced clarity.

Laser Blended Vision: An Innovative Solution

Laser blended vision, also known as PRESBYOND, is a revolutionary technique that utilizes advanced excimer laser technology to address presbyopia and achieve seamless vision at all distances.

This procedure is designed to create a natural transition between the eyes, allowing both eyes to work together harmoniously and simultaneously, providing a clear vision for both near and distant objects.

Unlike monovision, which relies on contact or intraocular lenses, laser blended vision offers a more permanent solution, reducing the need for additional devices or frequent replacements.

Monovision vs. Laser Blended Vision: Visual Outcomes and Quality of Vision

Near Vision Performance

Monovision involves correcting one eye for near vision and the other for distance vision. This method allows individuals to see nearby objects clearly without relying on reading glasses. In contrast, laser blended vision employs advanced laser technology to reshape the cornea gradually. 

This creates a smooth transition from near to intermediate and distant vision in both eyes. The aim is to achieve clear vision across all distances, reducing the need for additional visual aids.

Intermediate Vision Performance

Intermediate vision, which is essential for computer use and reading at arm’s length, can be critical for daily tasks. Monovision may provide satisfactory intermediate vision, but some individuals find it less clear and crisp than laser blended vision. PRESBYOND is designed to optimize intermediate vision by creating a balanced focus between both eyes.

Distance Vision Performance

While monovision can improve near vision, it may result in some compromise to distance vision performance. Some individuals may experience reduced depth perception or visual acuity when using both eyes together, especially in low-light conditions or situations that require sharp distance vision, such as driving at night.

Laser blended vision aims to optimize near and distance vision without stark separation. As a result, distance vision is generally better than traditional monovision because both eyes contribute to distance vision tasks.

Monovision vs. Laser Blended Vision: Adaptation Period and Neuroadaptation

Monovision Adaptation Period 

As the brain continues to receive different images from each eye (one for distance and the other for near vision), it learns to process this information effectively and use the input from both eyes in a complementary manner. Over time, the brain gets better at seamlessly switching between the two eyes, improving visual performance and reducing visual disturbances.

After getting fitted with monovision contact lenses, the brain needs time to adjust to this new setup. Initially, patients may experience some visual discrepancies and depth perception issues. It can take a few weeks for the brain to adapt to this new way of seeing and to determine which eye to use for different tasks.

Laser Blended Vision Adaptation Period

In PRESBYOND surgery, the neuroadaptation process is focused more on the brain adjusting to the new multifocal corneal surface rather than learning to rely on different eyes for different tasks. The brain needs to adapt to interpreting the different focal points provided by the multifocal cornea for various distances.

PRESBYOND aims to reduce the adaptation period by offering a more balanced and natural visual experience. The gradual corneal reshaping in both eyes allows for quicker neuroadaptation, helping patients adapt to the new vision faster.

Monovision vs. Laser Blended Vision: Patient Satisfaction and Long-Term Results


Patient satisfaction with monovision can vary significantly. While some individuals find it convenient and satisfactory, others may need help with reduced depth perception and visual clarity, especially in low-light conditions. Long-term success with monovision depends on each individual’s ability to adapt and their visual preferences.

Laser Blended Vision

Laser blended vision has shown high patient satisfaction rates due to its ability to provide clear vision at all distances without the drawbacks of monovision. Patients often report improved visual comfort and fewer visual disturbances, leading to higher long-term satisfaction.

Monovision vs. Laser Blended Vision: Potential Side Effects and Risks


Monovision may lead to visual disturbances, such as halos and glare, particularly during nighttime or in low-light conditions. Additionally, some individuals may find adjusting to using one eye for specific tasks challenging, affecting their overall visual experience.

Laser Blended Vision

As with any laser eye surgery, dry eyes can be a common side effect, but it is usually temporary. While both treatments carry potential risks, PRESBYOND’s advanced technology and precise corneal reshaping aim to minimize side effects such as visual disturbances.

Before considering any vision correction procedure, a detailed consultation with a seasoned eye care specialist is paramount. This step is essential in identifying the optimal solution for your vision requirements and lifestyle. 

By carefully evaluating each approach’s advantages and potential drawbacks, the eye care professional can help you make an informed choice that aligns with your circumstances.
