Are you tired of wearing glasses or daytime contact lenses? Orthokeratology lenses (Ortho-K) offer a revolutionary, non-surgical way to correct your vision while you sleep. These specially designed lenses gently reshape your cornea overnight, allowing you to enjoy clear, sharp vision throughout the day without glasses or contacts.
Whether you’re a child looking to control myopia or an adult seeking freedom from glasses, Ortho-K provides a safe, effective, and reversible solution.
What is Orthokeratology?
Orthokeratology, commonly called Ortho-K, is a non-invasive vision correction technique. Instead of undergoing surgery, Ortho-K reshapes the cornea (the clear front surface of the eye) temporarily using custom-fit rigid lenses worn overnight.
When you wake up, the reshaped cornea allows light to focus properly on the retina, giving you natural, glasses-free vision during the day. Ortho-K is suitable for:
Myopia (nearsightedness) up to -6.00 diopters
Hyperopia (farsightedness) up to +3.00 diopters
Astigmatism up to 1.50 diopters
How Do Ortho-K Lenses Work?
Ortho-K lenses are made of high oxygen-permeable material, ensuring your eyes stay healthy overnight. Their unique design includes a central vault and a tear reservoir that gently applies pressure to the cornea, reshaping it while you sleep.
Key Benefits of the Lens Design:
Gentle reshaping of the cornea for clear daytime vision
Comfortable, safe overnight wear
Custom-fit to each individual’s eye for precision
By wearing these lenses for 6–8 hours nightly, the cornea gradually flattens in areas where needed, correcting your refractive error. In the morning, remove the lenses, and enjoy sharp, natural vision all day.
Who Can Benefit from Ortho-K Lenses?
Children:
Controls myopia progression, preventing severe nearsightedness later in life
Non-invasive and safe alternative to eye surgery
Allows a glasses-free lifestyle during school and sports
Adults:
Ideal for active lifestyles or sports, where glasses or contacts may be inconvenient
Offers freedom from daytime contact lenses
Suitable for those not eligible for laser eye surgery
Pros & Cons of Orthokeratology

Is Ortho-K Permanent?
Ortho-K is temporary and reversible. The cornea gradually returns to its original shape if lenses are not worn, making it a safe, flexible choice for those hesitant about permanent procedures. Most users experience clear vision 12–24 hours after overnight wear, requiring nightly use for consistent results.
