Myopia Contact Lenses: MiSight Soft Contacts Explained
How do MiSight® 1 day contacts reduce the progression of your child’s near-sightedness? What’s the science behind these amazing lenses, proven to potentially reduce myopia progression by 59% over three years compared to single-vision lenses.
Myopia contact lenses are similar to regular lenses, in that they correct for short sighted vision errors. But MiSight lenses also reduce the stimulus for eyeball elongation, which is the source of myopia – a common problem in children today, with potentially serious long term negative consequences.
I’m Dr. Jotinder Khosla, an optometrist at Optometrist Parramatta. I understand the concerns parents have about their child’s vision and at our practice we aim to provide the best care possible. This article will guide you through the scientific mechanisms of MiSight contact lenses, helping you make an informed decision for your child’s eye health.

Myopia Control Mechanism of MiSight Contact Lenses
MiSight contact lenses utilise ActivControl® Dual-Focus Technology, which involves concentric rings that strategically focus light. This unique design ensures that while central vision remains clear, peripheral vision is intentionally blurred.
The science behind this is quite ingenious. By focusing light in front of the peripheral retina, the lenses create a myopic defocus. This defocus acts as a signal to the eye, slowing down the elongated growth of young eyeballs. The long-term efficacy of these lenses is supported by extensive research and clinical trials, making them a trusted option for parents looking to manage their child’s myopia.
By altering the way light enters the eye, MiSight lenses help in managing the physical changes that cause myopia. It’s a non-invasive, easy-to-implement solution that doesn’t interfere with daily activities. This makes it an ideal choice for children who need a practical and reliable way to manage their myopia.

Material Composition
MiSight contact lenses are crafted from Omafilcon A, a material renowned for its softness and flexibility. This composition ensures the lenses are comfortable to wear throughout the day. One of the important features of Omafilcon A is its 60% water content. This level of hydration is optimal for keeping the lenses moist and comfortable; crucial for children who may wear them for extended periods.
In addition to comfort, the material enhances oxygen permeability which is any important factor in maintaining healthy eyes. Good oxygen flow helps to prevent dryness and irritation, ensuring that the eyes remain healthy and lenses feel comfortable even when worn for long hours.
The soft material nature of Omafilcon A means the lenses conform to the shape of the eye, providing a snug fit. This adaptability reduces friction between the lens and the eye, minimising the risk of discomfort or damage. It’s a key feature that ensures the lenses remain comfortable and effective.
Technical Feature of Omafilcon A | Practical Benefit |
|---|---|
|
|
Refractive Index (1.40 at 25°C) | Provides clear and sharp vision, improving overall visual clarity. |
Excellent Surface Wettability | Ensures lenses remain lubricated, reducing friction and making them more comfortable. |
UV Blocking | Offers some protection against harmful UV rays, helping to safeguard your eyes. |
Non-Ionic Nature | Minimises protein buildup on the lenses, keeping them cleaner and clearer for longer. |
Visibility Tint Features
MiSight contact lenses come with a faint visibility tint that addresses several practical issues, particularly for children who are new to wearing contacts. The tint doesn’t affect visual clarity but makes the lenses much easier to see during daily handling. The visibility tint reduces the risk of losing them during the insertion or removal process. This feature is especially beneficial for young users who are still learning to handle their lenses confidently.
Furthermore, the visibility tint helps in maintaining the hygiene of the lenses. Since the lenses are easier to see, it’s simpler to check for any debris or damage before placing them in the eye. This reduces the likelihood of infections and ensures that the lenses remain clean and safe to use. For parents, this feature provides peace of mind, knowing that their child can handle their lenses more safely and effectively.
Overall, the visibility tint is a thoughtful addition that enhances the practicality and user-friendliness of MiSight contact lenses. It supports children in becoming more independent and confident in managing their eye care, which is a crucial step in long-term myopia control.
Daily Disposable Myopia Contact Lenses
MiSight contact lenses are designed to be used once and then discarded at the end of the day. This daily disposable format offers several advantages, particularly for children and their parents.
Firstly, using a fresh pair of lenses every day means there is no need for cleaning or disinfecting. This simplifies the entire process, making it much easier for children to manage their lenses. It eliminates the daily hassle of lens care, which can often be a stumbling block for young users and their parents. By removing this step, it reduces the risk of improper lens care, which can lead to eye infections or other complications.
Another significant benefit of daily disposables is the reduction in the risk of eye infections. Since each pair is only worn once, there is less opportunity for bacteria and other pathogens to accumulate on the lenses. This is particularly important for children, who may be less diligent about hygiene. The convenience of simply discarding the lenses after each use ensures a higher standard of cleanliness and eye health.
For busy families, the convenience of daily disposables cannot be overstated. Parents can rest assured that their child’s lenses are clean and safe every day without the added burden of nightly cleaning routines. This ease of use makes daily disposable lenses an ideal choice for managing myopia in children, combining effectiveness with practicality.

Conclusion
MiSight® 1 day contact lenses use dual-focus technology to slow the progression of myopia in children by creating myopic defocus. This defocus approach reduces the stimulus for the eyeball to become too long, which is the cause of myopia.
Without proper intervention, your child’s myopia is likely to worsen, resulting in stronger prescription needs and thicker glasses. Furthermore, high degrees of myopia raise the risk of glaucoma, retinal detachment, and myopic maculopathy later in life.
