A process that uses specialty contact lenses, known as orthokeratology (Ortho-K) gives patients a free and innovative way to treat their nearsightedness, also known as myopia. We’ve listed three benefits that Ortho-K lenses offer over traditional daytime contact lenses! Keep reading if you are curious…

  1. 1. Treat Your Vision Overnight

Ortho-K relies on a technology known as Corneal Refractive Therapy, also known as CRT. CRT lenses, such as Paragon CRT®, are worn overnight to treat nearsightedness while you sleep! These specialty lenses gently reshape the cornea, allowing light to refract correctly on the retina. When you wake up, you can simply remove the lenses and experience clear vision throughout the day! Paragon CRT® was the first overnight contact lens to be FDA approved, and 97% of patients report their satisfaction.1,2


  1. 2. No More Glasses or Daytime Contacts

With Ortho-K, you treat your vision only at night—no more need for glasses or daytime contact lenses! Paragon CRT® lenses give you freedom! After wearing our lenses overnight, you can start your day without thinking twice about your eyesight! Paragon CRT® free you from being slowed down by glasses or daytime contacts and the worries of them getting broken, lost, or dirty. Plus, with Paragon CRT®, you’ll have crystal clear vision in times when wearing glasses or contacts is impractical – like when you’re traveling, playing sports, or swimming.


  1. 3. The Confidence to Live Your Best Life

With Paragon CRT® you have the freedom to face whatever comes at you. When you wake up with clear vision, anything is possible! Researchers have found that people who treat their nearsightedness with orthokeratology experience improved quality of life and confidence.3,4 And why not? The ability to see clearly is essential to living your best life. With the power of Ortho-K lenses, patients are freed from scores of issues that come along with daytime vision correction. Imagine not scrambling to put your lenses in when you are rushing out the door for work, or not wondering where your glasses are when you are late for a meeting. From travel to yoga, hiking, climbing, and surfing, Paragon CRT® lenses deliver freedom to get out there and have fun!


Moreover, for the child or teen who is uninterested in glasses or contacts, Ortho-K ensures that their nearsightedness will be treated. High levels of myopia can cause serious risks later in life, such as macular degeneration, premature cataracts, glaucoma, retinal holes and tears, and even retinal detachment.5 Paragon CRT® gives young patients an easy way to take care of their eye health without visual correction interfering in their lives – and give you, the parent, peace of mind! As nearsightedness can affect children as young as six, having an easy treatment plan can make this diagnosis much more manageable.6
