Overnight Contact Lenses

Have you been diagnosed with myopia (nearsightedness), hyperopia (farsightedness), astigmatism (irregularities in the corneal curvature), or presbyopia (age-related hyperopia)? In that case, you may want to consider orthokeratology. This treatment corrects these refractive errors by reshaping the cornea and focusing the image on the retina.

Although Ortho-K is not a permanent solution, these overnight contact lenses can assist.

Patients sleep with these Ortho-K lenses in their eyes throughout the night. The correction consistently lasts throughout the day until it’s time to insert the lenses again before nighttime.

There are numerous advantages to donning these special night contact lenses at night, such as:

Clear sight

You may be wondering, “How do overnight contacts work? Wearing ortho-K lenses overnight can correct a patient’s vision so that they can experience visual freedom without contact lenses or spectacles during the day.

Physical performance

Ortho-K lenses are particularly advantageous for athletes, as they provide visual independence and eliminate the need for glasses or contact lenses to improve athletic performance. In many sports, donning glasses is prohibited, and contacts may be uncomfortable or distracting. Night contacts, such as Ortho-K lenses, provide the optimal solution by correcting vision at night so that the patient does not need to wear glasses during the day. A similar advantage of orthokeratology exists for professionals whose occupations require clear vision, such as pilots and drivers.


Not having to constantly wear spectacles or contacts is simply more convenient than the alternative. These lenses are worn while sleeping in orthokeratology, and the patient will not sense them.

No surgery required

Ortho-K lenses are a highly effective method of vision correction for patients who are ineligible for LASIK or other refractive surgery, particularly children and adolescents. In addition, Orthokeratology is wholly reversible if the treatment is discontinued and, as a result, carries no surgical risk.

Reduced myopia progression in infancy

In addition to providing daytime vision correction, research demonstrates that ortho-K lenses offer myopic children long-term clinical benefits. In the study, myopic children who wore orthokeratology lenses advanced substantially less than those who wore conventional contact lenses or eyeglasses. This benefit is of utmost importance in light of the obvious myopia epidemic and myopia’s alarming global expansion.

Orthokeratology is most effective for patients with modest to moderate refractive errors. Contact your local physician immediately if you are unsure whether this treatment is appropriate for you or your children.
