What if we told you that you could wake up each morning with clear vision—without wearing glasses or eye surgery? That’s the magic of Orthokeratology, commonly known as Ortho-K.
These specially designed contact lenses are worn overnight to gently reshape the front surface of your eye (the cornea), giving you glasses-free vision during the day. They’re safe, non-surgical, and Health Canada-approved for overnight wear. Our doctors at Northern Sight Optometry offer orthokeratology services to our patients in Vaughan and Kleinburg.
Ortho-K has been growing in popularity among kids, teens, and adults—and for good reason. Whether you’re an active adult tired of glasses or a parent looking for a way to slow your child’s myopia, Ortho-K might just be your perfect match.
What Is Ortho-K? 👁️
Ortho-K lenses are custom-fit rigid gas-permeable lenses that you put in before bed and remove in the morning. While you sleep, the lenses temporarily reshape the curvature of your cornea. This reshaping allows light to focus properly on the retina, improving your vision without the need for glasses or contacts during the day.
Think of it like gentle braces for your eyes—without any daytime hassle.
For Kids: Myopia Control + Daytime Freedom 👧🏽
One of the most exciting benefits of Ortho-K is its power to help slow the progression of myopia in children.

Nearsightedness isn’t just an inconvenience—it’s a growing concern. Higher levels of myopia increase the lifetime risk of serious eye conditions like retinal detachment, glaucoma, and macular degeneration. Ortho-K lenses have been shown in studies to reduce myopia progression by up to 50% or more in many children.
Here’s why Ortho-K is a fantastic option for kids:
Slows myopia progression (especially when started early)
Great for active lifestyles and athletics—no glasses to lose or break!
Nighttime use encourages consistent routines (and kids tend to follow hygiene instructions better than adults!)
Plus, Ortho-K eliminates worries about your child taking contacts in and out at school or losing their glasses after gym class.
For Adults: Freedom from Glasses (Without Surgery) 🧑🏼

Not a fan of wearing glasses during your workouts, at work, or out on date night? Not quite ready for laser eye surgery? Ortho-K gives adults a non-invasive, reversible way to experience clear daytime vision.
Whether you’re dealing with dry eyes from daytime contacts, discomfort during allergy season, or you simply want to be glasses-free without a long-term commitment, Ortho-K can provide:
All-day clear vision with no need for daytime correction
Freedom for travel and sports
A dry-eye-friendly option (since you don’t wear them during the day)
No permanent changes to the eye—stop wearing them, and your eyes return to normal
Bonus: For shift workers or those who prefer a more flexible lens-wearing schedule, Ortho-K offers customizable wear routines under your optometrist’s supervision.
Bonus Perks: No Waste During the Day 🌎
One of the hidden advantages of Ortho-K is that you’re not throwing out lenses daily, making it a more eco-conscious option.
For patients who want clearer vision while minimizing daytime waste, this is a great fit. (And for those in daily disposables, don’t worry—we also offer a contact lens recycling program!)
Ortho-K is more than just a lens—it’s a lifestyle upgrade. Whether you're helping your child protect their vision for the future or giving yourself the gift of hassle-free, glasses-free days, Ortho-K might be the solution you've been looking for.
