Are you looking for a contact lens that is clinically proven to slow the progression of myopia (nearsightedness)? Do you have a family history of high myopia and are looking for treatment options for your child? If so, you should highly consider CooperVision MiSight 1 Day contact lens!
In this article, I’ll review what you need to know about MiSight 1 Day contact lenses, including the pros and cons of wearing these lenses.
MUST READ: Best Contact Lenses Currently Available
Myopia rates are on the rise…
Did you recently discover that your child is nearsighted? Unfortunately, having myopic parents increases a child’s risk of myopia. In fact, one myopic parent increases the risk of myopia by 2-3 times and two myopic parents increase that risk to up to 6 times.
Worldwide, studies have implicated that while rates of myopia were only 1 in 4 people back in 2000, the rate will double to 1 out of every 2 people by 2050. Many factors from age to ethnicity and genetics to environmental factors are in play with these developments. We must also include the future medical care implications for this global population of myopic eyes.
It can be devastating for a child that already has insecurities to learn that they need glasses. While some children will happily choose a nice set of frames, others worry about teasing from friends or being singled out by peers. Better compliance with nearly invisible contact lenses also means a lower chance of serious vision problems.
What is MiSight 1 Day?
CooperVision’s MiSight 1 Day is the first soft contact lens that has been clinically proven with over 5 years worth of data to not just correct for myopia, but to also slow down the refractive error progression by 59% in children versus a single vision single-use lens.
Another endpoint that was studied was the clinical reduction in average axial lengthening down by 52% compared to control subjects. Addressing axial elongation helps to reduce the risk of myopia-related vision complications later in life, including irreversible vision loss due to myopic macular degeneration, retinal detachments, and more.
The ActivControl Technology in MiSight 1 Day utilizes an optic zone concentric ring design with alternating vision correction and treatment zones to achieve the above effect. Two zones are vision correction zones with the label power of the contact lens, and the alternating two zones are treatment zones with 2 diopters of defocus to slow the progression of myopia.
Your specially MiSight certified eye care provider will access the risk of myopic progression in your child. For example, a child that develops myopia at a younger age is at a significantly higher risk for progression. Another example that is clinically proven is the higher prevalence of myopia and progression in patients of East Asian ethnicities.
How do MiSight 1 Day contacts work?
The basis of myopia control contact lenses stemmed from studies that confirmed myopic eyes tend to have correlating peripheral hyperopia. For example, someone with -4.00 D of myopia may be -4.00 D at the fovea, but towards the periphery they could be -1.50 D. Hence, if they are corrected with a single vision spherical -4.00 D lens, the image falls behind the eye in the peripheral retina. This hyperopic defocus is a stimulus for eye elongation.
However, primate model studies by Earl Smith and colleagues in Houston showed that if we can create myopic defocus in the periphery, this is a stronger stimulus – slowing eye-growth. In these studies, primates were wearing lenses that created hyperopic and myopic defocused images at the same time. The result was that the eye-growth slowed down and preferentially grew towards the myopic defocus.
Powers, availability, and more
MiSight 1 Day contact lenses are available in powers ranging from -0.25D to -6.00D and were designed with a dual focus zone to control retinal defocus. Due to the nature of myopia control, no hyperopic/farsighted parameters exist.
When fit with MiSight 1 Day lenses by your eye care professional, you’ll receive a trial box that contains 5 contact lenses for each eye. Once your prescription is finalized, these contact lenses are conveniently available for purchase in 30 and 90 day lens packs! Also, as noted in the name, they are designed for daily wear and should be thrown away at the end of the day. Therefore, they’re NOT approved to be slept in!
Note: If you plan on taking your daily contact lenses out for a nap or to go swimming, we recommend storing them in Biotrue, RevitaLens, or Opti-free Pure Moist contact lens solutions. For more information on contact lens solutions, check out our complete guide!
What people are saying
- 90% of the children in the study preferred wearing MiSight 1 Day lenses over their glasses due to their comfort, vision, ease of use, and freedom from eyeglasses as top benefits.
- 90% of children in the study could apply and remove the MiSight 1 Day lenses on their own.
Is MiSight 1 Day right for you?
- FDA approved dual treatment zones create myopic defocus with image focus in front of the retina, rather than behind it to slow axial elongation.
- Two correction zones correct myopia in all gaze positions.
- Targets developmental years of children ages 8 to 12 years old.
- A convenient patient-facing app called Brilliant Futures Myopia Management Program for parents and patients to track progression, order annual supplies, and have access to published resources on myopia control.
- Comes with a moderate price tag (compared to other dailies) and requires a specialty myopia control evaluation by a certified optometrist.
- Not available in toric design at the moment.
- Slightly more restrictive FDA approved conditions for “on-label” myopia management.
- Must wear for a minimum of 10 hours a day and 6 days a week for proper myopia management.
How much does MiSight 1 Day cost?
As mentioned above, these specific lenses are priced higher due to the therapeutic myopia management effect and specialty fitting that must take place before ordering lenses. As a result, pricing varies from practice to practice and they are not available for purchase online.
These lenses have been a great option for my young patients with highly myopic parents that understand why I hesitate to “just prescribe stronger glasses.”
The daily lens promotes good ocular hygiene and compliance in an established lens material! I always make sure my myopia control patients and parents have realistic expectations that there are no treatments for curing myopia, rather we aim for the control of myopic progression.
