The condition is characterized by the eye’s inability to focus light directly on the retina, causing distant objects to appear blurred. Recent studies highlight a notable rise in the prevalence of myopia worldwide, attributed to both genetic and environmental factors. Environmental influences such as reduced outdoor activities, increased screen time, and early academic pressures are significant contributors to this trend [2][4][5][7][9].

MiSight® 1 Day Contact Lenses as a Pioneering Solution

In response to the escalating incidence of myopia, MiSight® 1 Day contact lenses have been developed as an innovative intervention. These lenses are specifically designed to control the progression of myopia in children. Clinical trials and meta-analyses have demonstrated the efficacy of MiSight® 1 Day lenses in slowing myopia progression through the dual-focus design, which provides both clear vision and a treatment effect [1][3][6][8]. The lenses have shown to significantly  slow down the elongation of the eyeball and the worsening of myopia over time compared to traditional single-vision lenses.

Scientific Principles and Advantages of MiSight® 1 Day Lenses

MiSight® 1 Day contact lenses operate on the principle of myopia control through optical defocus. The lens design incorporates concentric rings that create a relative peripheral myopic defocus, which has been suggested to slow the axial elongation of the eye—a key factor in myopia progression. This innovative approach not only corrects refractive error but also addresses the underlying progression of myopia. The advantages of using MiSight® 1 Day lenses include their ease of use as a daily disposable lens, reducing concerns about hygiene and maintenance, which are particularly pertinent in paediatric populations [1][3][6][8].

Understanding Myopia in Children

Myopia Occurrence and Mechanism

Myopia, also known as nearsightedness, happens when the eyeball stretches more than usual, making light rays converge in front of the retina instead of directly on it. This results in distant objects appearing blurry while close objects can be seen clearly [12]. The elongation of the eyeball can be influenced by both genetic and environmental factors, such as increased near work and limited outdoor activities [10][12][13].

Progression and Risks in Children

In children, myopia can progress rapidly, especially during growth spurts associated with adolescence [12]. This progression can lead to high myopia, which significantly increases the risk of developing serious ocular complications such as retinal detachment, glaucoma, and myopic maculopathy [12][15]. The rapid progression in children underscores the importance of early detection and intervention to manage the condition effectively.

Control Measures and Prevention

Given the rising trend of myopia among children, effective control measures are crucial. Recent studies have focused on various interventions to slow the progression of myopia in children. These include pharmacological interventions such as low-dose atropine eye drops, which have been shown to slow myopia progression [11][17]. Optical interventions like orthokeratology (Ortho-K) lenses and multifocal contact lenses are also effective in controlling axial elongation, the primary factor in myopia progression [16][18][20].

Children wearing multifocal contact lenses had slower progression of their myopia, according to results from a clinical trial funded by the National Eye Institute, part of the National Institutes of Health.

Environmental strategies, such as increasing outdoor activity, have been shown to have a protective effect against the onset and progression of myopia [21][22]. Public health initiatives and educational programs that encourage outdoor activities and regulate screen time are also recommended to mitigate the onset and progression of myopia in children [14][19].

What Makes MiSight® 1 Day Unique?

Specialized Design for Myopia Control

MiSight® 1 Day contact lenses are specifically engineered to control myopia, distinguishing them from standard contact lenses. These lenses are engineered to correct nearsightedness and also slow down the progression of myopia in children. Clinical studies have demonstrated the effectiveness of MiSight® 1 Day in managing myopia over extended periods. For instance, a long-term study showed that treatment with MiSight® 1 Day lenses resulted in sustained slowing of myopia progression over a six-year period [23]. This indicates that these lenses are more than corrective devices; they are therapeutic tools aimed at addressing the underlying progression of myopia in paediatric patients.

Unique Dual-Focus Technology

MiSight® 1 Day lenses incorporate Dual-Focus Technology, which is central to their function in myopia control. This technology involves a lens design with concentric rings that provide different optical powers. One ring corrects the refractive error (myopia), while the other creates myopic defocus, which has been shown to slow the progression of myopia. This dual-focus approach is clinically proven to be effective. For example, a randomized clinical trial highlighted that children wearing MiSight® lenses showed significantly less progression in myopia and axial elongation compared to those wearing conventional single-vision lenses [25]. This technology leverages the concept of peripheral defocus, which is instrumental in controlling eye growth, thereby reducing the rate at which myopia progresses in children.

FDA Approval and Clinical Validation

The FDA approval of MiSight® 1 Day lenses underscores their safety and efficacy. The approval was based on extensive clinical trials that demonstrated these lenses’ capability to safely slow down the progression of myopia in children. The FDA’s endorsement is based on rigorous evaluation standards, ensuring that the lenses meet safety criteria and provide the intended therapeutic effects. The clinical trials leading to FDA approval have shown consistent results in terms of efficacy in myopia control, reinforcing the lenses’ role as a significant advancement in paediatric eye care [24][25].

The Science of MiSight® 1 Day Lenses

MiSight® 1 Day contact lenses are specifically designed to manage myopia progression in children. The technology and design of these lenses are supported by clinical research and scientific studies that demonstrate their effectiveness in controlling myopic progression through innovative lens design.

Dual-Focus Technology

MiSight® 1 Day lenses utilize Dual-Focus Technology, which is engineered to create multiple focus areas within the lens. This technology is crucial because it directly addresses the issue of eye elongation, a significant factor in the progression of myopia. The lens design includes a central focus area that ensures clear vision for the wearer, while simultaneously incorporating concentric peripheral rings. These rings are not merely for structural support but play a critical role in managing how the eye grows, particularly in the peripheral areas. The peripheral treatment zones in these lenses create myopic defocus, which has been shown to signal the eye to halt further elongation—a process critical in slowing myopic progression [26][27][28].

Design and Functionality

The central focus area of MiSight® 1 Day lenses is designed for clear and sharp vision, which is essential for daily activities, especially in a learning environment for children. Surrounding this central zone are multiple concentric peripheral rings. These rings extend the depth of focus and have been specifically engineered to manage eye growth effectively. By extending the focus, these rings help in creating a form of myopic defocus, which is beneficial in controlling myopic progression. This design is not only innovative but directly targets the underlying changes in the eye’s structure that contribute to myopia [26][27][28].

Clinical Evidence and Studies

Several clinical studies have underscored the efficacy of MiSight® 1 Day lenses in managing myopia. For instance, a study by Chamberlain et al. (2024) highlighted that children wearing MiSight® lenses exhibited significantly slower progression of myopia compared to those wearing conventional single-vision lenses. This study, along with others, provides robust evidence supporting the use of MiSight® lenses as a viable intervention for myopia control in children. The studies consistently show a reduction in the rate of myopia progression and eye elongation, which are critical to reducing the long-term risks associated with high myopia, such as retinal detachment and glaucoma [26][27][28].

Daily Comfort

MiSight® lenses are designed as daily disposables, which contributes significantly to their comfort and suitability for children’s active lifestyles. Daily disposables are advantageous because they reduce the risk of infections associated with lens wear, such as microbial keratitis, which is often linked to improper lens care or extended wear schedules. The comfort of wearing MiSight lenses is supported by studies where subjects reported high levels of comfort and satisfaction with these lenses. For example, a study assessing the comfort of various daily disposable lenses found that users reported high initial comfort scores, which were maintained throughout long periods of wear [31][32].

Visual Health

Long-term use of MiSight® lenses not only controls myopia progression but also contributes to better overall visual health outcomes. By controlling myopia progression, these lenses help in reducing the risks associated with high myopia, including retinal detachment, macular degeneration, and glaucoma. The effectiveness of MiSight lenses in providing these health benefits is supported by their ability to significantly slow down changes in axial length and spherical equivalent refraction, which are critical factors in the progression of myopia and related complications [30].
