Clear daytime vision. No daytime lenses.
Ortho-K is a non-surgical, reversible contact lens treatment designed to gently reshape the front surface of the eye while you sleep — helping you wake up to clearer vision during the day without glasses or daytime contact lenses.
Lenses that work when you aren’t wearing them.
Designed for children, teens, active adults, sports players, dry-eye sufferers, and people who want practical freedom from daytime eyewear.
Glasses help you see clearly — but they may not always fit your lifestyle.
For many families, the problem is not just blurry vision. It is sport, school, screen time, dry eyes, broken glasses, lost lenses, and the worry that a child’s myopia may keep progressing.
Active kids and sports
Ortho-K gives children and teens the freedom to run, swim, play sport, and wear sunglasses during the day without worrying about glasses or daytime contacts.
Freedom from daytime eyewear
Because lenses are worn at night, many patients can enjoy clear daytime vision without relying on glasses or soft contact lenses throughout the day.
Myopia management support
For children with progressive myopia, Ortho-K is used as a myopia control option and may help slow myopia progression with ongoing monitoring.
A gentle overnight lens treatment for clearer vision by day.
Orthokeratology, commonly called Ortho-K, uses custom-designed rigid gas permeable lenses worn during sleep. The lenses gently reshape the cornea — the clear front surface of the eye — to correct refractive error and improve daytime vision.
The treatment is non-surgical and reversible. If lens wear stops, the cornea gradually returns to its original shape, so ongoing wear is needed to maintain the effect.
- ✓Suitable for many people with myopia, hyperopia, astigmatism, and some presbyopia needs after assessment.
- ✓Custom-designed using detailed corneal measurements and topography mapping.
- ✓Designed for clear vision during the day without wearing the lenses during daytime activities.
Simple for patients. Highly customised by your optometrist.
Ortho-K uses the eyelid and tear fluid beneath the lens to reshape the top layers of the cornea overnight. For myopia, this creates a flatter central cornea to reduce the focusing power of the eye.
Comprehensive eye exam and suitability check
Your optometrist checks your vision, eye health, prescription, lifestyle needs, and whether your corneas are healthy and suitable for Ortho-K.
Corneal topography mapping
A corneal topographer maps the exact shape of your eye. These measurements help design a personalised lens matched to your eye shape.
Custom lens design
Your lens is digitally designed and simulated using detailed corneal data, helping reduce the need for uncomfortable trial fitting and unnecessary lens changes.
Lens delivery and training
You are taught how to insert, remove, clean, store, and care for your lenses safely before beginning overnight wear.
First morning and follow-up reviews
Your optometrist checks your vision, lens fit, corneal reshaping, and eye health. Follow-up appointments are essential to successful and safe treatment.
Many patients notice improvement quickly, with vision stabilising over time.
Some people notice clearer vision after the first night. Most patients need a short adjustment period, and more complex prescriptions may take longer to reach full correction.
First night
You may notice improvement the next day. Some patients achieve about half of the required correction after one night, depending on their prescription.
First 1–2 weeks
Vision usually becomes clearer and more stable. Some temporary glasses or soft lenses may be recommended during the transition phase.
Ongoing care
Regular reviews help monitor eye health, lens performance, and long-term suitability. Lenses are commonly replaced every one to two years.
Ortho-K is ideal for people who want clear vision without daytime lens wear.
It is especially useful when glasses or daytime contacts get in the way of school, sport, work, comfort, or lifestyle.
Children, teens and sports players
Great for people who play contact or water sports, where glasses can be damaged and soft contacts can feel inconvenient or risky.
- ✓No glasses slipping during sport.
- ✓No daytime contact lenses falling out.
- ✓More freedom for swimming, running and outdoor play.
Dry eyes, allergies and computer work
Ortho-K may suit people who find daytime soft contacts uncomfortable due to dry eyes, allergies, computer use, air conditioning, or dusty work environments.
- ✓No daytime contact lens dryness.
- ✓Useful for long screen days and air-conditioned environments.
- ✓Practical for trades, dusty workplaces and active routines.
More than clear vision — Ortho-K can be part of a myopia control plan.
Childhood myopia can progress over time. Ortho-K is commonly used for children and teenagers because it can provide daytime visual freedom while also supporting myopia management under professional care.
At Eye Philosophy, your child’s treatment journey should be guided by clear education, careful lens handling training, routine follow-ups, and ongoing eye health monitoring.
Parent-friendly takeaway: Ortho-K is worn while your child sleeps, then removed in the morning — giving them clear vision for school, sport and daily life without glasses during the day.
Suitability depends on prescription, corneal shape, eye health, hygiene routine, and the child’s ability to follow lens care instructions with family support.
Why choose Ortho-K instead of glasses, soft contacts or laser?
Every option has its place. The right choice depends on age, eye health, prescription, comfort, lifestyle and long-term goals.
| Option | Best for | Key consideration |
|---|---|---|
| Ortho-K | People who want clear daytime vision without daytime lenses or glasses; children needing myopia control support. | Requires nightly lens wear, hygiene, and regular follow-up appointments. |
| Glasses | Simple, low-maintenance correction for everyday vision. | Can be limiting for sport, active children, water activities and some work environments. |
| Soft contact lenses | Daytime glasses-free vision for suitable wearers. | May be uncomfortable with dry eyes, allergies, dust, screens or long wear hours. |
| Laser vision correction | Adults seeking a surgical vision correction option. | Not suitable for children, is not reversible like Ortho-K, and may not suit some dry-eye patients. |
Successful Ortho-K depends on careful fitting, hygiene and follow-up care.
Like any contact lens, Ortho-K requires correct cleaning, handling and monitoring. Your optometrist will teach you or your child how to care for the lenses and what symptoms to watch for.
Important lens care reminders
- ✓Wash and dry hands thoroughly before touching lenses.
- ✓Use the correct cleaning, storage and lubricating solutions.
- ✓Attend all scheduled reviews, especially during the first weeks.
- ✓Contact the clinic promptly for pain, redness, unusual light sensitivity or sudden vision changes.
Questions parents and patients ask before starting Ortho-K.
Is Ortho-K permanent?
No. Ortho-K is reversible. If you stop wearing the lenses, your cornea gradually returns to its original shape and your prescription returns over time.
How long does it take to see results?
Many patients notice improvement after the first night. Stable vision usually develops over the first one to two weeks, while higher prescriptions or more complex cases may take longer.
Does my child need to wear the lenses every night?
Most patients wear Ortho-K lenses every night, especially during the early stage. Some low prescriptions may later maintain good daytime vision with less frequent wear, but this must be guided by the optometrist.
Can children use Ortho-K?
Yes, many children and teenagers use Ortho-K. Suitability depends on prescription, eye health, corneal shape, maturity, hygiene, and family support with the lens routine.
Can I see while the lenses are in?
Yes. The front surface of the Ortho-K lens provides optics, so you can still see if you wake up during the night. The lenses are generally not intended for daytime wear.
What if I forget to wear the lenses for one night?
Your vision may be slightly blurrier the next day as the cornea starts to return to its original shape. Wearing the lenses again usually restores the effect, depending on your case.
How often are the lenses replaced?
Ortho-K lenses are typically replaced every one to two years depending on their condition and your optometrist’s recommendation.
How do I know if Ortho-K is right for me?
The best first step is a suitability consultation. Your optometrist will assess your prescription, corneal shape, eye health, lifestyle, and treatment goals before recommending a plan.
