FOR CONCERNED PARENTS
This may be for your child if…
Their prescription
keeps changing
New glasses every year and you are not sure how strong it will get next time.
You want to explore
myopia control
You have heard about options beyond regular glasses and want clear, honest guidance.
They are active and
glasses get in the way
Sports, swimming, or daily life would be easier with clear vision without daytime lenses.
WHAT IS ORTHO-K?
Overnight Lenses for
Clearer Daytime Vision
Ortho-K uses custom-designed overnight contact lenses that are worn while your child sleeps. The lenses gently and temporarily reshape the front surface of the eye, helping many patients see more clearly during the day without glasses or daytime contact lenses.
How the process works
1
Custom Fit
Lenses are designed based on your child’s eye shape and prescription.
2
Overnight Wear
The lenses are worn during sleep and removed in the morning.
3
Daytime Vision
Many patients experience clearer vision during the day without glasses or daytime contact lenses.
4
Follow-up Care
Dr. Fong monitors vision, comfort, lens fit, and eye health over time.
Important to know: Ortho-k does not cure myopia. The effect is temporary and requires consistent overnight wear, proper cleaning, and regular follow-up care.
Start wth a Consulation,
Not a Commitment
Ortho-K is not right for every child. The first step is to understand your child's eyes, perscription, lifestyle, and whether overnight lens case is realitic for your family
