Ortho-K Lenses: How They Correct Vision While You Sleep

Imagine waking up each morning with clear vision - without reaching for glasses or putting in contact lenses. Orthokeratology, commonly known as Ortho-K, makes this possible by gently correcting vision while you sleep. Ortho-K lenses are a non-surgical option for managing nearsightedness (myopia) and reducing daytime dependence on corrective eyewear.

What Are Ortho-K Lenses?

Ortho-K lenses are specially designed, rigid gas-permeable contact lenses worn overnight. While you sleep, the lenses gently reshape the surface of the cornea. This temporary reshaping allows light to focus properly on the retina, resulting in clearer vision during the day - without the need for glasses or contacts.

Once the lenses are removed in the morning, most patients experience clear vision that lasts throughout the day. The effect is reversible, meaning consistent nightly wear is needed to maintain results.

How Do Ortho-K Lenses Work?

The cornea plays a major role in how light enters the eye. In people with myopia, the cornea’s shape causes light to focus in front of the retina instead of directly on it. Ortho-K lenses apply precise, controlled pressure to flatten the central cornea slightly while redistributing cells toward the periphery.

This reshaping process:

· Improves how light focuses inside the eye

· Corrects mild to moderate nearsightedness

· Provides clear daytime vision without lenses

Because the changes are temporary, Ortho-K is considered a safe and non-invasive alternative to refractive surgery.

Who Can Benefit from Ortho-K?

Ortho-K lenses are an excellent option for:

· Children and teens with progressing myopia, as Ortho-K has been shown to help slow myopia progression

· Adults who want freedom from daytime glasses or contacts

· Active individuals or athletes who prefer not to wear eyewear during sports

· Patients who are not candidates for LASIK or prefer a non-surgical solution

A comprehensive eye exam is essential to determine if Ortho-K is right for your eyes and vision goals.

What Happens to Your Eyes Overnight with Ortho-K Lenses?

Ortho-K lenses work by gently reshaping the cornea while you sleep, when your eyes are closed and stable. This overnight wear allows the lenses to stay properly positioned for several hours, creating precise corneal changes that improve vision by morning.

As you sleep, Ortho-K lenses:

· Use a controlled tear film to gently reshape the cornea

· Flatten the central cornea to correct nearsightedness (myopia)

· Improve how light focuses on the retina

· Maintain healthy corneal structure without surgery

The reshaping process is temporary, safe, and painless. After removing the lenses in the morning, most patients enjoy clear vision throughout the day without glasses or contact lenses. Consistent nightly wear helps maintain results, while skipping nights allows the cornea to gradually return to its original shape.
