For many people who struggle with nearsightedness (myopia), daytime glasses or contact lenses are a daily necessity. But what if you could enjoy clear vision during the day without wearing corrective lenses? Corneal Refractive Therapy (CRT) makes this possible by gently reshaping your cornea while you sleep.
 

What Are CRT Lenses?

CRT lenses are specially designed, FDA-approved contact lenses that work overnight. Unlike standard contacts, which provide vision correction only while they are worn, CRT lenses use a process called orthokeratology (Ortho-K) to temporarily reshape the front surface of the eye (the cornea). This subtle reshaping corrects the way light enters the eye, allowing you to see clearly without glasses or daytime contacts the next day.
 

How Do CRT Lenses Work Overnight?

The lenses are custom-fitted to your unique eye shape and are made from a highly breathable material that allows oxygen to pass through to your cornea while you sleep.
 

•          Gentle reshaping: While you rest, the lenses apply slight pressure to the cornea, flattening it in a controlled way.

•          Temporary correction: This change adjusts how light focuses on your retina, correcting nearsightedness and sometimes astigmatism.

•          Daytime freedom: By morning, the lenses are removed, and you can enjoy clear vision throughout the day without glasses or contacts.
 

Most patients notice significant improvement within the first few nights of use, with maximum correction typically achieved in about 1-2 weeks of consistent wear.
 

Benefits of CRT Lenses

•          Glasses-free lifestyle: Perfect for people who play sports, swim, or work in environments where glasses and contacts are inconvenient.

•          Non-surgical alternative: Offers vision correction without the risks or permanence of LASIK surgery.

•          Myopia control in children: CRT lenses are especially effective in slowing the progression of myopia in children and teens, helping to reduce long-term vision risks.
 

Who Is a Good Candidate?

CRT lenses are ideal for children with progressing nearsightedness, adults who aren’t ready for surgery, and anyone looking for a safe, reversible way to enjoy clear vision without daytime lenses. A comprehensive eye exam is the best way to determine if CRT is right for you.
 

Take the First Step Toward Glasses-Free Vision

CRT lenses provide a unique, non-invasive way to achieve clear daytime vision by simply wearing corrective lenses at night. Whether you’re looking for freedom from glasses, a non-surgical solution, or a way to help your child manage myopia, CRT may be the answer.
