How Ortho-K Works
Gentle overnight corneal reshaping for clear daytime vision
The Science
Ortho-K uses specially designed rigid gas permeable lenses worn during sleep. These lenses gently flatten the center of the cornea, temporarily correcting myopia and creating peripheral defocus that signals the eye to slow its growth.
Lenses worn only during sleep (8+ hours)
Cornea gently reshaped overnight
Clear vision all day without correction
Overnight Wear Only
Children wear lenses while sleeping, removing them in the morning for glasses-free days.
Daytime Freedom
Perfect for active children who play sports or don't want to wear glasses during school.
Fully Reversible
The effect is temporary—stop wearing and your cornea returns to its original shape within days.

Frequently Asked Questions
Is Ortho-K safe for children?
Yes, when properly fitted and cared for. Ortho-K has been used safely for decades. The key is proper hygiene and regular follow-up visits with your eye care provider.
How long does it take to see results?
Most children notice improved vision after the first night. Full effect typically occurs within 1-2 weeks of consistent wear.
What happens if my child stops wearing the lenses?
The effect is fully reversible. Vision will return to its original state within a few days to a week after stopping lens wear.
Can my child play sports with Ortho-K?
Absolutely! That's one of the biggest benefits. Since lenses are worn at night, children have clear, glasses-free vision for all daytime activities including sports.
How often do the lenses need to be replaced?
Typically every 1-2 years, depending on the lens material and how well they're maintained. Your eye care provider will monitor lens condition at follow-up visits.
