Overnight Corrective Lenses

What is Orthokeratology? All-Day Clear, Glasses Free Sight 

What is Orthokeratology? Orthokeratology or Ortho-K are contact lenses worn at night that change the curvature or shape of the cornea — correcting how light is focused by your eye. Ortho-k lenses are specifically designed to be used at night and removed once you wake up. As you sleep, the lenses gently reshape the eye, giving you all-day clear sight without wearing glasses or other contact lenses. Orthokeratology is used to treat, and even eliminate refractive errors such as:

  • Myopia
  • Hyperopia
  • Astigmatism

What is Orthokeratology and is it for me?

Almost anyone with myopia, hyperopia, or astigmatism is a good candidate for the ortho-K treatment.

If you play sports, participate in outdoor activities, or have a busy lifestyle, ortho-k lenses may be an ideal option for you. Many of the downsides of wearing day time contact lenses — dust, pollutants, irritation, and dryness — can be avoided by wearing ortho-k lenses while you sleep and going contacts free during the day.

Orthokeratology for All-Day Clear Sight 

contact lens care, What is Orthokeratology



Answer the following questions to see if Orthokeratology is the right treatment option for you.

  Are you farsighted (hyperopic), nearsighted (myopic) or have an astigmatism with a prescription in the range of +2.00 to -10.00?

  Are you unable to wear soft contact lenses for any reason, such as discomfort, allergies, dryness or inconvenience?

 Does your profession require you to have excellent vision without the use of glasses or contacts?

  Do you just not want to wear contact lenses or glasses during the day?

If you answered “Yes” to any (or all) of the questions above, then Ortho-K lenses may be a good option for you. These lenses are fairly easy to use and are only worn while you sleep, which reduces any of the discomfort you may have experienced while using conventional contact lenses.

Overnight Results with Ortho-K

See immediate results with ortho-k lenses, with vision-clearing effects lasting up to 2 full days. During that time, the vision blur that previously plagued you will be mostly or entirely gone. For best results, patients are encouraged to wear their lenses while sleeping every night. You can also wear your orthokeratology lenses during the day, but they are typically  less comfortable for daytime wear than other types of contact lenses.

Children See Fantastic Results With Orthokeratology 

Early intervention is considered beneficial, if not essential

Kids or young adults are often perfect candidates for ortho-K since treatments like LASIK or refractive surgery aren’t possible. Whether your child wants, or needs, to be glasses-free, they can see terrific results from wearing ortho-k lenses every night.

What is Orthokeratology

Studies from around the world have indicated that if your child is nearsighted, Orthokeratology can keep their nearsightedness from getting worse. Currently, an ongoing 5-year FDA study is showing data that is providing further evidence and support for this claim with results that are observable, testable and repeatable.

Increasing nearsightedness can put your child at increased risk for retinal detachments and glaucoma.

If your child has a tendency to lose or break their glasses or contact lenses, or if wearing glasses or contact lenses interferes with their daily activities, Orthokeratology may be right for them. Here are some other alternatives to eyeglasses for children.
