What to do about childhood myopia? The eyes are the windows to the soul, conveying emotions like joy and sorrow. Parents dream of their children having bright, sparkling eyes! From birth, a child’s eyes undergo physiological development, with vision gradually maturing—requiring lifelong protection. Today, more children wear thick glasses from a young age, burdening their studies and daily lives. Ages 3–12 have become the "high-risk zone" for myopia! In this era of digital screens, 70.4% of children regularly use electronic devices. While parents recognize the importance of eye health, myopia rates among young children continue to rise!
However, once a child develops myopia, parents worry most about…
They can’t undergo laser surgery before age 18!
What methods can slow rapid myopia progression? Orthokeratology (Ortho-K) lenses are a leading solution.
Current medical technology cannot cure myopia. During childhood and adolescence, scientific eye care—such as outdoor activities, reducing prolonged near work, and proper screen use—can prevent, control, and slow myopia. If parents notice vision abnormalities, they should promptly visit an ophthalmology clinic for evaluation and follow medical advice for Ortho-K therapy.
Case Study: A Boy Wearing Ortho-K Lenses
Liangliang, a young boy in Hangzhou, is one of many children using Ortho-K lenses at Ren Tree Medical. He told his mother that his vision for school blackboards had blurred. She immediately brought him to Ren Tree for Ortho-K fitting.
One day after wearing the lenses, his uncorrected vision improved. His mother was thrilled, and Liangliang jumped for joy. Ren Tree’s pediatric myopia control team, with years of experience, felt deeply gratified.
What Are Orthokeratology Lenses?
Ortho-K lenses, or "OK lenses," are rigid gas-permeable contact lenses with a unique design. Unlike regular soft lenses, they reshape the cornea’s central curvature overnight, restoring clear daytime vision without glasses.
How Do OK Lenses Control Myopia?
By temporarily reducing corneal curvature, OK lenses correct central refractive errors and address peripheral hyperopic defocus—effectively slowing excessive axial elongation in children. They are particularly suitable for axial myopia with rapid eye growth.
Age Requirements for OK Lenses
Recommended for ages 8+ (and adults without presbyopia), provided there are no ocular or refractive contraindications.
Eligible Prescriptions
Myopia: Below 600 diopters
Astigmatism: Below 200 diopters
Clinic Requirements for Fitting
OK lenses must be fitted by licensed ophthalmologists at certified institutions to ensure safety and efficacy.
