Key Takeaways
You wake up, take your contacts out, and get to see clearly for the rest of the day. That’s the appeal of orthokeratology (also called ortho-k), a lens-based approach to vision correction that works while you sleep.
Ortho-k lenses are only available through a registered optometrist who has the equipment to map your cornea and fit lenses custom-made for your eyes.
At Lowy and Sewell Eye Care, we work with patients to find the right fit for their vision and lifestyle. If you’ve been wondering where to get ortho-k lenses or what the process looks like, here’s what you need to know.
What Orthokeratology Lenses Do
Ortho-k lenses are rigid contact lenses that you wear while you sleep. They apply gentle pressure to your cornea overnight, temporarily changing its shape so that light focuses more accurately on your retina. In the morning, you remove your lenses and go about your day with clearer vision.
The effect is not permanent. If you stop wearing the lenses, your cornea gradually returns to its original shape, and your vision shifts back as well. For many people, that’s a reassuring feature, as it means that you can try ortho-k without committing to any long-term changes.
If you’re curious about how corneal mapping works, it uses a photography technique that builds a detailed 3D model of your cornea’s surface, and that map is what makes custom lens design possible.
Who Can Wear Ortho-K Lenses
Prescriptions That Qualify
Ortho-k lenses are most commonly used for myopia or nearsightedness. In other words, if you find that distant objects look blurry without correction, you may be a good fit. However, ortho-k can also address mild to moderate astigmatism and some cases of farsightedness.
A thorough exam with an optometrist in Vaughan can confirm whether your prescription falls within the range that ortho-k can address effectively.
Ages and Lifestyles That Benefit
Two groups tend to benefit the most. For children with myopia, ortho-k has been shown to help slow the progression of the condition. For active adults who find daytime lenses inconvenient, ortho-k can simplify daily routines. In particular, swimmers, athletes, and people who work in dusty or dry environments often find wearing contacts during the day uncomfortable or impractical.
For families with children showing signs of worsening vision, myopia control options like ortho-k are worth discussing. Our myopia resource offers helpful tools for parents navigating myopia in children, including risk assessment guides developed by eye care professionals.
How the Fitting Process Works
What to Expect at Your First Appointment
Fitting ortho-k lenses isn’t a simple trial-and-error process. It starts with corneal mapping, which creates a detailed 3D model of the surface of your eye. Your optometrist reviews that data carefully before ordering your lenses.

Follow-Up Visits After Your Fitting
After the first night of wear, a follow-up appointment helps confirm that the lenses are sitting correctly and that the cornea is responding well. A second check around the one-week mark gives an even clearer picture. These visits aren’t optional extras. They’re a built-in part of getting ortho-k right.
Where to Buy Ortho-K Lenses and What It Costs
Why You Need a Registered Optometrist
Ortho-k lenses aren’t available online or at a general retailer. They require a valid prescription and can only be provided through a licensed eye care provider. The fitting process depends on equipment that isn’t accessible outside a clinical setting.
Optometrists in Vaughan who offer ortho-k have the training and tools to map your cornea accurately, order the right lenses, and monitor your response over time.
What Factors Affect the Cost
The cost of ortho-k varies. A more complex prescription typically means a more involved lens design, which can affect pricing. Consultation fees may be included in a package or billed separately, depending on the practice. For a detailed breakdown of what to expect financially, our ortho-k cost guide walks through typical pricing and what’s usually included in the first year.
One thing worth noting is that ortho-k lenses are more durable than daily or monthly disposables. This can help balance the upfront cost over time.
How to Care for Your Ortho-K Lenses
Taking care of your lenses is straightforward once you build the habit. Clean and disinfect your lenses every day using the solution recommended by your optometrist. Never rinse your lenses or lens case with tap water, as tap water carries microorganisms that can lead to serious eye infections.
Ongoing follow-up appointments are also part of a good routine. At these appointments, your optometrist monitors how your cornea is responding over time and checks for any early signs that need attention.
