How Ortho-K (Night Lenses) Works to Slow Nearsightedness Progression

What if clear vision during the day didn’t require glasses or contact lenses - and could also help slow nearsightedness from getting worse? At Vision One Eyecare, we offer Ortho-K as a non-surgical solution for families in Katy, TX who want to manage myopia while enjoying clear, glasses-free vision during the day.

What Is Ortho-K?

Ortho-K uses specially designed rigid gas-permeable contact lenses that are worn overnight. While you sleep, the lenses gently reshape the front surface of the eye (the cornea). When the lenses are removed in the morning, light focuses more clearly on the retina, providing sharp daytime vision without the need for corrective eyewear. Unlike daytime contact lenses, Ortho-K lenses are only worn at night, making them especially appealing for children, athletes, and individuals with active lifestyles.

How Ortho-K Slows Myopia Progression

When standard lenses are worn, light can still focus slightly behind the retina in the peripheral vision, which may signal the eye to continue growing longer - worsening myopia. Ortho-K lenses reshape the cornea in a way that helps redirect peripheral light to focus in front of or directly on the retina instead.

This change in peripheral focus sends a signal that reduces excessive eye growth, which is the underlying cause of myopia progression. Clinical studies have shown that Ortho-K can slow nearsightedness progression by up to 50% or more in many children.

Who Is a Good Candidate for Ortho-K?

Ortho-K is commonly recommended for:

•          Children and teens with progressive myopia

•          Adults with mild to moderate nearsightedness

•          Patients who want freedom from glasses or daytime contacts

•          Athletes or individuals with active lifestyles

•          Those who are not ready for or not candidates for laser vision correction

A comprehensive eye exam and corneal mapping are required to determine candidacy and ensure proper lens design.

What to Expect During Ortho-K Treatment

The Ortho-K process begins with a thorough evaluation and precise measurements of your eyes. Custom lenses are designed specifically for your corneal shape. During the first few nights, vision gradually improves, with most patients achieving clear daytime vision within one to two weeks. Regular follow-up visits are essential to monitor eye health, lens fit, and myopia control effectiveness.

Is Ortho-K Safe?

When properly prescribed and monitored by an experienced eye care provider, Ortho-K is considered safe and effective. Like all contact lens treatments, success depends on good hygiene, consistent wear, and routine follow-up care. At Vision One Eyecare, patient education and ongoing monitoring are key parts of our Ortho-K program.
