MiSight vs Ortho-K: An In-depth Look into the World of Vision Correction

Back to Blogs

When it comes to correcting vision issues such as myopia (nearsightedness), options abound. Among these, MiSight and Orthokeratology (Ortho-K) have risen as two viable choices for individuals, especially children. Both have their unique attributes, benefits, and drawbacks.

But how do they compare? As an eager consumer, you might find yourself in a sea of information, weighing MiSight vs Ortho-K. This article provides an in-depth comparison to help you make an informed decision.

Understanding MiSight

In the world of vision correction, MiSight emerges as a beacon of innovation. Developed by CooperVision, these daily disposable contact lenses are designed to slow down myopia progression, mainly in children.

What is MiSight?

MiSight is not just another pair of contact lenses. These are specially engineered lenses designed to manage myopia, a condition that results in distant objects appearing blurry while close objects are seen clearly. Commonly known as nearsightedness, myopia is a common issue among children and adolescents. MiSight's unique design helps to control this myopia progression in kids, promising a future with better vision. While it does not reverse or “fix” myopia, by reducing progression, it reduces risks of other problems associated with increased myopia.

How does MiSight work?

MiSight employs a principle known as myopic defocus to reduce myopia progression. These lenses present multiple focus points to the eye, manipulating the way light enters the eye. Light from distant objects is made to focus in front of the retina rather than directly on it. This process disrupts the stimulus that typically encourages the eye to grow longer, which is the root cause of myopia.

Benefits of MiSight

MiSight brings a slew of benefits to the table. They're convenient - as daily disposable lenses, there's no need for regular cleaning or storage. This convenience also translates into health benefits as the risk of eye infections drops due to minimal handling of lenses.

Moreover, studies suggest that MiSight lenses can slow myopia progression by up to 59% compared to regular single-vision lenses. This significant reduction can mean less severe myopia in adulthood and a lower risk of associated future eye problems such as glaucoma, retinal detachment, and cataracts.

Understanding Ortho-K

Orthokeratology, or Ortho-K, provides another intriguing approach to combat myopia. This non-surgical process involves wearing specially designed gas-permeable contact lenses, primarily while you sleep.

What is Ortho-K?

Ortho-K involves the use of rigid, gas-permeable contact lenses designed to reshape the cornea temporarily. This reshaping process is entirely reversible and non-surgical, making Ortho-K an attractive option for many individuals uncomfortable with the idea of a permanent surgical procedure.

How does Ortho-K work?

Ortho-K lenses work by exerting a gentle pressure on the eye's cornea to reshape it overnight. This reshaping ensures that light entering the eye is focused correctly, improving vision. The effects of Ortho-K are temporary, meaning the lenses need to be worn consistently each night to maintain the improved vision.

Benefits of Ortho-K

Ortho-K offers several unique advantages. One of the most significant benefits is the freedom it provides from wearing glasses or contact lenses during the day. This freedom is especially appealing to athletes or those with active lifestyles, where glasses or contacts can be inconvenient or disruptive.

Ortho-K has been shown to slow myopia progression in children effectively. The corneal reshaping helps reduce the eye's elongation, the key driver of myopia, similarly to MiSight lenses.

MiSight vs Ortho-K: The Comparison

Having unraveled the workings of both MiSight and Ortho-K, it's time to pit them against each other in various categories to help you make an informed choice.


When comparing MiSight and Ortho-K based on effectiveness, both options hold their ground. Both have been clinically proven to slow down myopia progression effectively. The choice between the two will often boil down to personal preference, lifestyle, and the individual's comfort with wearing contact lenses.


Regarding safety, both MiSight and Ortho-K are generally considered safe when used correctly and under professional supervision. However, any contact lens use comes with a small risk of eye infections, particularly if the lenses aren't properly cared for or if hygiene practices are overlooked. As MiSight lenses are daily disposables, the risk might be slightly less than with Ortho-K, which requires careful cleaning and storage.


Ortho-K generally has a higher upfront cost due to the need for custom lenses and frequent follow-up appointments, especially in the initial phase. In contrast, MiSight may seem more affordable at the outset, but keep in mind the continuous cost of daily disposables, which could add up over time.

Age Factors

Both MiSight and Ortho-K can be used by children. However, Ortho-K is typically recommended for older kids and teenagers, as they may be more capable of maintaining proper lens hygiene. MiSight, being a daily disposable lens, could be a more practical option for younger children.

In the end, the choice between MiSight and Ortho-K is a highly personal one, contingent on individual preferences, lifestyle, and specific vision correction needs. An eye care professional should always guide the decision, ensuring the chosen option is safe and suitable.

Remember, whether you opt for MiSight or Ortho-K, the goal is the same: to slow down the progression of myopia and to safeguard your or your child's vision for the future.

Leave your worries at the door and enjoy a clearer and healthier vision.
