Paragon CRT® Contact Lenses
It’s Your Life… See it Without Limits
Don’t let glasses or daytime contacts get in the way of your active lifestyle!


Sierra is a professional rock climber, social media influencer, a world traveler, and has been a Paragon CRT® patient for 10 years.

Glasses or traditional contacts can get in the way when enjoying your favorite sport or activity. Paragon CRT® Contact Lenses treat nearsightedness, also known as myopia without the restraint of daytime contacts or glasses. Unlike conventional contacts our lenses are worn overnight. They gently reshape the curvature of your cornea while you sleep. In the morning, you remove your lenses and enjoy corrected vision that lasts all day.

Whether you’re at the pool, on the trail, or at the gym, if you live an active lifestyle, Paragon CRT® Lenses might be perfect for you!
